How to do daily maintenance of modified asphalt equipment

Emulsified asphalt (ingredients: asphaltene and resin) heating tank is a new type of equipment for heating emulsified asphalt. Its appearance replaces the traditional thermal oil heating equipment, which brings great convenience to our users and improves work efficiency. Then let’s take a detailed look at how it is better than the traditional thermal oil heating equipment.
Emulsified asphalt (ingredients: asphaltene and resin) heating tank is another new type of emulsified asphalt heating storage equipment developed by technically separating the characteristics of traditional thermal oil heating emulsified asphalt tanks and internal heat part (part) rapid emulsified asphalt heating tanks. The automatic circulation program of the asphalt heating equipment enables the asphalt to automatically enter the heater, dust collector, induced draft fan, asphalt pump, asphalt temperature display, water level display, and steam generator as required.
It consists of pipeline and asphalt pump preheating system, pressure relief system steam combustion system, tank cleaning system, oil unloading tank installation, etc. All are installed on the tank body (inside) to form a compact integrated structure. It fully compensates for the shortcomings of traditional thermal oil heating equipment, such as long heating time and high energy consumption.

For each equipment used, certain safety knowledge must be followed. For the use of emulsified asphalt equipment, detailed instructions are given:
1. Placement: The emulsified asphalt equipment should be placed on a flat place, the front axle should be fixed to the sleepers, and the tires should be dangling. The machine should not be fiddled with at will to affect normal operation.
2. Regularly check whether the mixer blades are deformed and the screws are loose.
3. Check whether the running direction of the mixing drum is consistent with the direction of the arrow. Please replace the positive and negative poles of the terminal.
4. Before turning on the power, check the no-load test run, check for air leakage, and check the idling speed of the mixing barrel. The normal speed is about 3 times faster than the empty car. If not, stop the inspection.
5. If the asphalt material is stopped for one hour after mixing, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water in the barrel to prevent the formula from changing, so that the page and other links will rust. Sinoroader will provide you with more safe emulsified asphalt knowledge, please continue to browse.

The fine surface is made of stone with a single particle size, which has high wear resistance and anti-slip properties. The construction of the fine surface adopts mechanized construction, which requires less manual labor and has the characteristics of fast construction speed, anti-skid and noise reduction.
The special bonding material for fine surfaces produced by Sinoroader Group has the characteristics of good bonding performance and good durability. The specific construction process is roughly as follows:

Asphalt sealant is a material specially used for road crack repair. The following is a detailed introduction to asphalt sealant:
1. Definition and composition
Asphalt sealant is a road repair material made of asphalt or modified asphalt as the base material, with a certain amount of additives and fillers added, and processed by special technology. It usually has a black or dark brown appearance and is in a solid or semi-solid form.
2. Main characteristics
High adhesion: Asphalt sealant can firmly bond to the crack wall of the road surface to form a tight sealing layer to prevent moisture and other harmful substances from invading the road surface structure.
High elasticity: It has a certain elastic recovery ability and can adapt to the expansion and contraction changes of the road surface to prevent further expansion of cracks.
Weather resistance: After special process treatment, it has good weather resistance and can maintain its stable performance for a long time.
Convenient construction: The construction operation is simple and fast, without complex construction machinery, which reduces the construction cost.
3. Scope of application
Asphalt sealant is widely used in crack repair of various asphalt pavements, including highways, urban roads, airport runways, etc. At the same time, it can also be used for the maintenance and repair of asphalt surfaces such as bridges, tunnels, and parking lots.

With the continuous improvement of science and technology in my country, the application and popularization of bitumen emulsion equipment are also increasing. So how to check whether the configuration meets the standards? Only products that meet the standards can bring us benefits. We must pay attention to this issue. Next, please have a detailed understanding with our factory staff:
1. First of all, we need to check the modified emulsifier. If the gap between the bitumen emulsion colloid mill of the emulsifier will become larger during operation, we need to adjust it before continuous production;
2. Analyze the problem of the modifier. Under normal circumstances, we need to check whether the amount of modifier added is accurate. The time of addition should also adjust the pH value according to the difference in water quality used. This work needs to be operated by technical personnel;
3. Another major reason is caused by the problem of the bitumen emulsion configuration itself. When producing bitumen emulsion, it is necessary to check in advance whether the bitumen material used meets the quality standards.

Working conditions of asphalt debarreling equipment:
(1) Outdoor temperature: 20°C (average temperature of day and night)
(2) Heat exchange oil: 320 ℃
(3) Loading time is not included (because the personnel equipped in each unit are different, so the loading time is also different)
(4) There is no fluctuation in oil temperature (optimal automatic burner)
(5) The working temperature of the oil furnace is 220-260 ℃
(6) The flow rate of the oil circulation pump is not less than 50m3/h traffic
(7) When the outdoor temperature is lower than 20℃, the output decreases. The lower the temperature, the lower the output, and the higher the temperature, the higher the output.
(8) The greater the deformation of the asphalt barrel, the greater the impact on the output

We should select products that meet the specifications, and we should not select raw materials that do not meet the specifications. The other thing is the operation technology of asphalt heating equipment. Skilled operation technology is the most important, and training is required before taking up the post.
In recent years, with the continuous development of various industries, the production of various equipment including modified asphalt equipment has been further developed and applied. Professionals introduced that in the process of using modified asphalt equipment for production, the terminal control system implements full automatic control of medium weight, working temperature, working flow, valve opening and closing, etc., thereby ensuring the quality of modified asphalt and greatly improving production efficiency. Now Shandong Duxiu Factory will explain the operating advantages of modified asphalt equipment to customers:
The base asphalt is heated to 150-170℃ in the rapid heating tank and then enters the blending tank to mix with the modifier fed in through the feeding device. The asphalt pump at the bottom of the blending tank then sends it to the colloid mill for high-speed grinding and shearing, so that the modifier and base asphalt are fully dissolved in extremely small particles, thereby improving the various properties of the asphalt. The finished modified asphalt after high-speed shearing and grinding enters the finished product development tank at the rear for direct use.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

The application of slurry mixes in highways and municipal engineering projects is of significant importance and widespread practicality. The following is a detailed analysis of their applications in these two areas:
I. Highway Applications
1. Applications of Colored Polymer Slurry Mixtures
Advantages: A variety of colors, environmentally friendly and durable, easy application, fast curing, and wear and skid resistance.
Applications: Colorful highway pavement designs, such as the Beijing-Dezhou Expressway, utilize colored polymer slurry mixes for their pavement design. This creates a visual impact for drivers, relieves fatigue, and serves as a warning.

2. Applications of Slurry Seals
Types: Slurry seals primarily include slurry seals and micro-surfacing.
Advantages: Excellent anti-skid properties, waterproofing and anti-seepage properties, rapid application, and cost-effectiveness.

Improve the understanding of the importance of preventive maintenance
We should further improve the understanding of the importance of preventive maintenance and raise preventive maintenance to the level of highway asset protection and road protection. At present, leaders at all levels and maintenance departments do not fully understand the significance of preventive maintenance of asphalt pavement. We should deepen our understanding of the important role of preventive maintenance and improve the strategic awareness, initiative and creativity of preventive maintenance. At the same time, the maintenance department should strengthen communication and exchanges with transportation authorities and financial management departments at all levels, so that departments at all levels understand the importance and necessity of preventive maintenance and create conditions for the implementation of preventive maintenance and funding sources. At the same time, it is very necessary to add preventive maintenance to the classification of maintenance projects, which will help the management of leaders at all levels and the implementation of preventive maintenance.
Improve the decision-making and planning of preventive maintenance
According to the decision-making and planning process, reasonably arrange the preventive maintenance of asphalt concrete pavement structure to ensure the safe and stable operation of highway projects throughout the life cycle, and reduce production costs while providing high-quality traffic services. Therefore, the key to preventive maintenance of asphalt concrete pavement structure lies in establishing a scientific decision-making and planning mechanism. The Ministry of Transport proposed in the “13th Five-Year Plan for Highway Maintenance Management Development” that the average annual mileage of preventive maintenance for expressways should not be less than 8%, and that for ordinary national and provincial roads should not be less than 5%. In the actual application process, local governments should also actively summarize experience and propose different preventive maintenance ratios based on the specific conditions of different regions.

Colored asphalt pavement is a kind of special pavement material that mixes colored particles into asphalt and then lays on the pavement

The fiber-reinforced synchronous sealing vehicle is a special vehicle used for road construction and maintenance, mainly for processes such as gravel sealing. This vehicle plays a vital role in road construction and maintenance, helping to ensure the flatness and durability of the road surface and improve the service life of the road.
First, the fiber-reinforced synchronous sealing vehicle adopts advanced synchronous sealing technology, which can accurately control the spraying and distribution of gravel to ensure the uniformity and quality of the road sealing layer. This precise construction method can effectively improve the flatness and pressure resistance of the road surface, reduce the possibility of road damage and breakage, and extend the service life of the road.
Secondly, the use of fiber-reinforced synchronous sealing vehicles can improve the efficiency and quality of road construction and maintenance. Through the automated construction process, quality problems caused by human errors and irregular operations can be reduced, and the consistency and stability of construction can be improved. This not only saves manpower and time costs, but also improves the overall efficiency of road construction and maintenance.
In addition, the fiber-reinforced synchronous sealing vehicle can also reduce the impact of the construction site on the environment. The use of advanced spraying technology and material recovery devices can reduce the waste of gravel and materials, reduce the interference and pollution of construction to the surrounding environment, and conform to the concept of sustainable development.
In general, fiber-reinforced synchronous sealing vehicles are of great significance in road construction and maintenance. They not only improve the service life and quality of roads, but also improve construction efficiency and reduce the impact on the environment. With the continuous advancement of science and technology and the improvement of engineering technology, it is believed that fiber-reinforced synchronous sealing vehicles will play a more important role in future road construction and maintenance, and contribute more to the construction and maintenance of transportation infrastructure.

In order to better play the role of slurry seal vehicles, this article explains the matters that should be noted from the aspects of the scope of application, type and material selection, construction technology, common diseases, etc. of slurry seal vehicles.
The slurry seal vehicle is thin in thickness and mainly plays the role of waterproofing, anti-skid, wear-resistant and improving the appearance of the road surface. In the pavement structure system, it can only serve as a surface protection layer and wear layer, but not a load-bearing structure. It is widely used in the construction and maintenance of highways. Practice has proved that the slurry seal can also play an important role by reasonably selecting the thickness and type of the slurry seal and strictly controlling the construction technology and quality.
(1). The scope of application of slurry seal vehicles includes the following aspects:
1. When the pavement damage index of expressways and first-class highways is evaluated as medium and below, or the pavement damage index of second-class and below highways is evaluated as secondary and below, when medium repair and overlay measures should be taken, slurry seal can be selected.
2. When the pavement driving quality index of expressways and first-class highways is evaluated as medium or below, or the pavement driving quality index of second-class and below highways is evaluated as second or below, medium repair and overlay measures should be taken to improve its flatness, and slurry seal can be selected.
3. For sections of expressways and first-class highways with insufficient anti-skid capacity (SFC<40), or sections of second-class and below highways with insufficient anti-skid capacity (SFC<33.5), measures such as adding overlays should be taken to provide anti-skid capacity of the road surface. 4. Anti-skid layer and waterproof protective layer used for third- and fourth-class highways to improve the appearance of the road surface.

Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreading truck, check the four heat transfer oil valves and air pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Try running the asphalt pump and cycle for 5 minutes. If the pump head shell is hot to your hands, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not rotate or make noise. You need to open the valve and continue to heat the asphalt pump until it can operate normally.

The bitumen decanter equipment is mainly composed of barrel removal shell (BOX), hoisting mechanism, hydraulic booster and electrical control system. The shell is divided into two chambers, the left and right chambers. The upper chamber is a chamber for melting a large barrel of bitumen (definition: the transformation process of a substance from solid to liquid). There are heating coils evenly distributed around it.

All kinds of base layers have the problem of strength formation and growth (Emerson). The strength is gradually generated during the curing process, and the internal structure will become more and more dense. The test shows that when the semi-rigid base layer is sprayed with penetration oil before the cement (material: powdered water-hardening inorganic cementitious material) has not yet hardened, the penetration depth is deep; with the increase of age and strength, the penetration effect of the penetration oil is getting worse and worse.
At the same time, timely spreading of penetration oil has a good retention effect on the moisture in the base layer, preventing the evaporation of moisture, ensuring the formation of the strength of the base layer, and the surface of the base layer is not easy to loosen. The penetration oil also protects the semi-rigid base layer from cracking due to exposure to the sun. Furthermore, since the base layer is no longer covered and watered for curing, the temperature inside the base layer is high, which is conducive to the growth of strength.

Asphalt spreader vehicle is an intelligent and automated high-tech product that specializes in spreading emulsified asphalt, diluted asphalt, hot asphalt, high-viscosity modified asphalt, etc.
Asphalt spreader is used for spreading the penetration oil, waterproof layer, and bonding layer of the bottom layer of the asphalt pavement of high-grade highways. The spreader consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, an ignition system, a control system, a pneumatic system, and an operating platform.
Asphalt spreader is cumbersome to operate. On the basis of absorbing various technologies of similar products at home and abroad, it increases the quality technology content of construction and the humanized design of outstanding improvement of construction conditions and construction environment. Its reasonable and reliable design ensures the uniformity of asphalt spreading, the computer control is stable and reliable, and the technical performance of the whole vehicle has reached an advanced level.

Microsurfacing is a thin layer of overlay placed on old asphalt pavement and is a type of preventive maintenance process. The purpose of microsurfacing is road maintenance. After micro-surface paving, it can repair cracks in the original road surface, waterproof and beautify the road surface.
The construction method of micro surfacing is: using a micro surfacing paver to evenly spread modified emulsified asphalt, a certain grade of mineral materials, water and other additives on the road surface in a certain proportion.

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

1 Common diseases of asphalt pavement
There are nine phenomena of early damage to asphalt pavement: rutting, cracks, and potholes. These diseases are the most common and serious, and are one of the common quality problems of highway projects.
1.1 Rutting
Rutting refers to the longitudinal strip grooves on the road surface along the wheel tracks, with a depth of more than 1.5cm. Rutting is a strip groove formed by the accumulation of permanent deformation of the road surface under the repeated action of vehicle load. Rutting reduces the smoothness of the road surface. When the rutting reaches a certain depth, due to the accumulation of water in the rutting, it is easy for cars to slide and cause traffic accidents. The main reasons for rutting are unreasonable design and serious overloading of vehicles.
1.2 Cracks
There are three main forms of cracks: longitudinal cracks, transverse cracks and mesh cracks. When cracks occur in asphalt pavement, water seepage occurs, which harms the surface layer and base layer.
1.3 Potholes
Potholes are common early diseases of asphalt pavement, which refer to the road surface being damaged into potholes with a depth of more than 2cm and an area of ??more than 0.04㎡. The main reason for the formation of potholes is that the oil used in vehicle repair or motor vehicles seeps into the road surface, polluting the asphalt mixture and causing it to loosen. The pits are gradually formed by driving and rolling.

There are many types of emulsified bitumen, and PC-2 is one of them, which is a spray-type emulsified bitumen. It is used for spraying oil through the base layer of granular materials and health care spraying on semi-rigid base layers. There is also the PA-2 type, which has the same purpose as the PC-2 type. The difference is that the PC-2 type is a cation, while the PA-2 type is an anion.

Emulsified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first ensure the safe use of emulsified asphalt equipment to fully demonstrate its performance; modified asphalt equipment is an asphalt binder made by adding rubber, resin, high molecular polymer, ground rubber powder or other fillers and other admixtures (modifiers), or taking measures such as mild oxidation of asphalt to improve the performance of asphalt or asphalt mixture; So how much do you know about the safe use and operation of modified asphalt equipment? Today, the editor will tell you;
Placement: The modified asphalt equipment should be placed on a flat place, and the front axle wheel should be fixed with sleepers and the tires should be dangling to ensure the stability of the machine during work.
Regularly inspect whether the mixer blades are deformed and whether the screws are loose.
Inspect whether the running direction of the mixing barrel is consistent with the arrow; if not, please replace the positive and negative poles of the wiring.
Before powering on, you should inspect and test run the empty vehicle, check for leakage, and check the idling of the mixing barrel. The normal speed is about 3 times faster when the empty vehicle is full. If the speed is wrong, you should stop the machine and check the asphalt tank.
Note: After the asphalt material is mixed, it is best to stop the machine for one hour, clean the drain material in the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water accumulation in the barrel to prevent the formula from changing, and the blades are prone to rust. During use, everyone should pay attention to these small links to avoid unnecessary losses to their work.

The viscosity of emulsified asphalt equipment decreases with the increase of temperature during the production process. The power viscosity of emulsified asphalt equipment is about twice as high as every 12℃ increase. During processing, the culture medium asphalt barrel should be heated to liquid before demulsification. In order to better integrate the demulsification emulsified asphalt equipment capacity of the colloid solution mill, the culture medium asphalt barrel power viscosity is generally controlled to be about 200cst. The lower the temperature, the higher the viscosity, which increases the pressure of the asphalt barrel pump and the colloid solution mill, and the emulsion cannot be demulsified. However, on the other hand, in order to prevent the emulsified asphalt equipment from weaning when the finished product water evaporates, it is unlikely to overheat the culture medium asphalt barrel temperature. Generally, the finished product temperature at the inlet and outlet of the colloid solution mill should be less than 85℃.
One of the important methods to control the temperature and viscosity of emulsified asphalt equipment during processing is based on this. Everyone must carry out scientific operation according to the instructions of the emulsified asphalt equipment, so that the characteristics of the emulsified asphalt equipment can be fully presented. The development trend of the drying theory of emulsified asphalt equipment requires the stone resources to be processed, dried and heated. The reason for the emulsified asphalt equipment is that the quality of wet raw materials does not meet the requirements of asphalt mixture production and processing technology equipment companies.

In the cold winter, you need to pay attention to the following points when using asphalt melting equipment:
1. Protection from cold and warmth: The equipment needs to be operated indoors or in a place with shading facilities, and ensure that the temperature of the equipment and the surrounding environment is maintained within an appropriate range.
2. Check the equipment: Before use, the equipment should be checked, including whether the circuits, fluid circuits and other parts of the equipment are working normally, and whether there are any leaks of electricity or water in the equipment.
3. Pay attention to safety: During operation, you should wear protective equipment and avoid direct contact with hot asphalt. At the same time, it is necessary to avoid equipment overload operation and prevent equipment damage and safety accidents.
4. Control speed: Reasonably control the working speed of the equipment according to weather conditions and road conditions to avoid overheating of the equipment, causing asphalt to flow too quickly or burn.
5. Storage conditions: When not in use, place the device in a dry, ventilated place with moderate temperature, and ensure that any residue in the device is completely removed.

Every two years (or every 1,000 hours worked)；

Asphalt spreader is used to spread the penetration oil, waterproof layer and bonding layer of the bottom layer of asphalt pavement of high-grade highway. It can also be used for the construction of county and township highway oil roads with layered paving technology. It consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.
Knowing how to properly operate and maintain the asphalt spreader can not only extend the service life of the equipment, but also enable the construction project to proceed smoothly. So what problems should the asphalt spreader pay attention to when working? The technicians of Gaoyuan Road Construction Machinery Equipment Co., Ltd. give you tips:
1). Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreader, check the four thermal oil valves and the pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Test the asphalt pump and circulate for 5 minutes. If the pump head shell is hot, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not turn or make noise. In this case, the valve needs to be opened to continue heating the asphalt pump until it can operate normally. During the working process, the asphalt liquid must be kept at a working temperature of 160~180℃, and it cannot be filled too full (pay attention to the liquid level pointer during the injection of asphalt liquid, and check the tank mouth at any time). After the asphalt liquid is injected, the filling port must be closed tightly to prevent the asphalt liquid from overflowing during transportation.
2). During use, asphalt may not be pumped in. At this time, it is necessary to check whether the interface of the asphalt suction pipe is leaking. When the asphalt pump and pipeline are blocked by solidified asphalt, a blowtorch can be used for baking, and the pump must not be forced to turn. When baking, care should be taken to avoid directly baking the ball valve and rubber parts.
3). When spraying asphalt, the car should be driven at a low speed. Do not step on the accelerator hard, otherwise it may cause damage to the clutch, asphalt pump and other components. If 6m wide asphalt is spread, pay attention to obstacles on both sides at any time to prevent collision with the spreading pipe. At the same time, the asphalt should be kept in a large circulation state until the spreading work is completed. After the work is completed every day, if there is any remaining asphalt, it must be returned to the asphalt pool, otherwise it will solidify in the tank and cannot work next time.
4). In addition, the emulsifier must also pay attention to daily maintenance:
1. The emulsifier and delivery pump and other motors, agitators, and valves should be maintained daily.
2. The emulsifier should be cleaned after work every day.
3. The speed regulating pump used to control the flow should be regularly tested for accuracy, and adjusted and maintained in time. The asphalt emulsifier should regularly check the matching clearance between its stator and rotor. When the minimum clearance specified by the machine cannot be reached, the stator and rotor should be replaced.
4. If the equipment is out of use for a long time, the liquid in the tank and pipeline should be emptied (the emulsifier aqueous solution should not be stored for a long time), the hole covers should be tightly closed, kept clean, and the running parts should be filled with lubricating oil. When it is used for the first time or when it is used again after a long period of inactivity, the rust in the tank should be removed, and the water filter should be cleaned regularly.
5. Regularly check whether the terminal in the electric control cabinet is loose, whether the wires are worn during shipment, and remove dust to avoid damage to the machine parts. The frequency converter is a precision instrument. Please refer to the instruction manual for specific use and maintenance.
6. There is a heat transfer oil coil in the emulsifier water solution heating stirring tank. When injecting cold water into the water tank, the heat transfer oil switch should be turned off first, and then the switch should be turned on to heat after adding the required amount of water. Pouring cold water directly into the high-temperature heat transfer oil pipeline can easily cause the weld to crack.

With the increase in the service life of road networks in various regions, how to extend the service life of roads has become an urgent problem that needs to be solved. At present, there are many ways to renovate and reinforce asphalt roads, and they are also relatively mature, such as cold regeneration technology, micro-surfacing technology, fine surfacing technology, fog sealing technology, etc., which can greatly increase the service life of roads.
