2. It is strictly prohibited to use non-specified fuel as the fuel for the heating system. The fuel is not allowed to overflow outside the tank. Generally, the oil level should be 20-30cm lower than the upper end of the overflow pipe.

For the relevant knowledge of modified asphalt equipment, we have more or less introduced it in the above articles. I believe that most users also have some simple understanding of it. Today we also mastered:
In order to meet the different requirements of customers, the configuration and process of the equipment produced by the manufacturers of modified asphalt equipment are diversified. There are fixed production types, mobile types, and imported main machines, but the imported main machines are expensive, so most customers configure domestic pipeline emulsifiers or colloid mills. In terms of the degree of automation, there are fully automatic production and semi-automatic production. Regardless of the form of production, each has its own advantages and disadvantages. What kind of process and configuration is used depends on the annual production volume and the customer’s requirements for equipment, product performance requirements and other factors. I hope that these introductions can help users choose to a certain extent.

Asphalt spreading truck is a kind of black ground construction machinery. It is an important equipment in the logistics construction of roads, municipal roads, airports and ports. This equipment is mainly used to spray different types of asphalt on the ground to meet the construction requirements of different levels of ground oil permeable layer, sticky layer, left and right permeable layer, fog permeable layer, etc.

Everyone has a side of themselves that they don’t want others to know. As a preventive road maintenance technology, slurry sealing has some shortcomings. do you think so?
Slurry seal is a kind of road protection that uses special equipment to mix emulsified asphalt, water, additives, aggregates, fillers and other ingredients in a certain proportion, and then mixes the slurry mixture onto the original road surface to form a thin layer. Maintenance technology. These are all well known. The editor will not go into details on this.

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.

Each F1 track must be paved with three layers of asphalt, middle and lower, of which the lowest layer is 10 cm coarse asphalt concrete bearing layer, its flatness is less than 8 mm; In the middle is a 4 cm medium grained asphalt concrete bond layer, its flatness is less than 5 mm; The top layer uses 4 cm modified asphalt mixture as the surface wear layer, and the flatness is less than 2 mm.

The paved F1 track cannot have more than 3 points per kilometer of flatness detection, which is much higher than the highway.

The asphalt spreading truck is an intelligent high-tech product that specializes in spreading emulsified asphalt, diluted asphalt, hot asphalt, heavy traffic asphalt and modified asphalt. It is used in highway construction and highway maintenance projects, and can be used for the construction of upper and lower seals, permeable layers, waterproof layers, bonding layers, asphalt surface treatment, asphalt penetration pavements, fog seals and other projects of different grades of highway pavements. , can also be used for the transportation of liquid asphalt or other heavy oil. So what are the advantages of Qiangguomeng’s asphalt spreader trucks?

Emulsified asphalt is to melt the asphalt and disperse it in a water solution containing a certain amount of emulsifier in the form of tiny droplets through the action of emulsifier and machinery to form an oil-in-water asphalt emulsion. This emulsion is in the form of dry liquid at room temperature. Modified emulsified asphalt refers to a modified asphalt mixed emulsion with certain characteristics prepared by blending, mixing and preparing it with emulsified asphalt as the base material and asphalt modification material as the external modification material under a certain process flow. This mixed emulsion is called modified emulsified asphalt.
The modified production process of emulsified asphalt can be divided into four categories:
1. Adding latex modifier after making emulsified asphalt, that is, emulsification first and then modification;
The production process is to grind the hot asphalt and emulsifier soap solution together through colloid mill to make ordinary emulsified asphalt, and then add the latex modifier to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The advantage of this method is that it does not require high equipment, and the disadvantage is that it is suitable for latex modifiers.
2. The latex modifier is mixed into the emulsifier aqueous solution, and then it enters the colloid mill together with the asphalt to produce modified emulsified asphalt;
3. The latex modifier, emulsifier aqueous solution, and asphalt are put into the colloid mill at the same time to produce modified emulsified asphalt (the two methods 2 and 3 can be collectively referred to as emulsification and modification);
The modifier is mixed into the emulsifier soap solution, and then the “modified” soap solution and asphalt are put into the colloid mill together to make modified emulsified asphalt; or the modifier is not pre-added to the emulsifier soap solution, but is placed in a tank separately, and finally mixed with the emulsifier, acid, water, etc. in the pumping pipeline and then enters the colloid mill together with the hot asphalt.
The method of adding latex modifier to the soap tank has the advantage that it is exactly the same as the process of producing ordinary emulsified asphalt, and no changes are required to the production equipment; the disadvantage is that when using this method to produce modified emulsified asphalt, the metering of the modifier is subject to certain restrictions, and the modifier latex is required to be able to withstand the pH value of the soap solution. The method of directly connecting the latex modifier to the colloid mill through a pipeline can overcome the above disadvantages, but it requires necessary improvements to the ordinary emulsified asphalt equipment before it can be used for the production of modified emulsified asphalt.
4. Emulsify the modified asphalt to produce emulsified modified asphalt.
The ready-made modified asphalt is heated to a certain temperature, becomes a flowing state, and then enters the colloid mill together with the soap solution to make emulsified modified asphalt. In the entire asphalt production process, due to the high viscosity characteristics of the asphalt itself and the high temperature environment required for production, various high-performance pumps and valves play a vital role in the asphalt transportation process.

Energy conservation and environmental protection are also excellent ways for Chinese companies to break down foreign trade barriers. By the end of 2011, the annual fuel consumption of my country’s construction machinery products exceeded the total annual output value of construction machinery. Currently, market entry barriers in countries like the United States and Japan are rising, and emission standards are a primary concern among these trade barriers. Industry experts believe that energy conservation and emission reduction in the construction machinery industry are challenging, often hindered by technical bottlenecks. Therefore, increasing research and development efforts is an effective way to address this situation. Energy conservation and environmental protection are the inevitable trends in the development of China’s construction machinery industry.
Whether it is to reduce environmental burdens or break down foreign trade barriers, energy conservation and environmental protection will become the mainstream trend in the development of construction machinery. The future development of China’s construction machinery industry will place greater emphasis on transformation and upgrading, and energy conservation and environmental protection will be a key focus in its implementation strategies. Currently, construction machinery manufacturers are incorporating more energy-saving and environmental protection elements into their new products. At the just-concluded biennial Shanghai Bauma Show, renowned international construction machinery companies like Komatsu, Hyundai, and Volvo Construction Equipment, as well as Chinese construction machinery giants like Sany, XCMG, Zoomlion, and Liugong, showcased their latest equipment, all boasting enhanced energy-saving and environmental performance. This demonstrates that the future of construction machinery will inevitably be dominated by energy conservation and environmental protection. Construction machinery companies must prioritize their own efforts to achieve higher product efficiency and superior energy-saving and consumption-reduction performance.

Some of the equipment of emulsified modified bitumen equipment are as follows. The specially made bitumen filter can effectively filter the residues and dirt in the high-temperature culture medium bitumen to avoid damage to the subsequent equipment. The emulsified modified bitumen equipment adopts a spiral plate type or a shell and tube heat exchanger to quickly heat the culture medium bitumen through high-temperature heat transfer oil to meet the needs of the production process. The emulsified modified bitumen equipment is heated in the storage tank to prevent the bitumen from aging due to long-term high-temperature heating and exposure to the air. The sulfate generated during the production process of the emulsified modified bitumen equipment is very limited, reducing air pollution.
The emulsified modified bitumen equipment sends the modified material manually poured into the dumping bin to the bitumen batching tank by wind or spiral. It can be equipped with a metering and calibration system. The emulsified modified bitumen equipment thickener is automatically or manually added. The emulsified modified bitumen equipment can be equipped with a metering and calibration system. Emulsified modified bitumen equipment transportation and metering and calibration system, the emulsified modified bitumen equipment adds the set bitumen amount to the batching tank through the frequency converter and computer interlock.

There are certain standards for the composition and mix ratio of micro-surfacing, and a wide range of materials are used, including polymer-modified emulsified asphalt, various aggregates, cement, water, additives, etc. Raw material quality has a significant impact on microsurfacing performance, so understanding the performance of each component and the key factors that influence its performance is critical to ensuring the quality of your microsurfacing mix.

The slurry seal truck is one of the main maintenance methods of highways. The slurry seal is made of emulsified asphalt as the binding material, well-graded mineral materials, fillers, water and additives, etc., mixed in a certain proportion. The slurry mixture is evenly spread on the old road surface to be treated with a sealing truck, and is firmly combined with the original road surface to form a new thin layer of asphalt mixture. So what preparations need to be done before construction? Let’s find out below.

Slurry sealers are important equipment for road maintenance and repair. They are mainly used to pour durable asphalt mixtures on old roads to form a new protective layer. This equipment can be constructed according to the surface texture of the road surface, so that the cracks in the surface layer are isolated from water and air, effectively preventing the road surface from aging further.
The working principle of the slurry sealer is to mix materials such as aggregate, emulsified asphalt and additives into slurry, and then evenly lay it on the road surface. The slurry formed after the mixture of these materials has good waterproof and skid resistance, which can significantly improve the service life of the road surface and driving safety.

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.

Barrel heating tank. The temperature of hot mixed asphalt barrels achieves the appropriate storage temperature.
When the water level in the drum is lower than the temperature of the thermometer, please close the suction valve before the drum pump is shut down to prevent the drum from flowing back in the heater. After the motor has been running for 2 days, the three-way valve opens quickly.

Asphalt distributors can spray, lay, and compact asphalt, improving construction efficiency and ensuring project quality.
Asphalt distributors play a crucial role in modern road construction. They not only efficiently apply asphalt but also assist with laying and compacting, providing strong technical support for road construction. So, how do asphalt distributors accomplish these three key tasks? Let’s take a closer look.
1. Asphalt Spraying: Uniform and Efficient, Improving Project Quality
One of the primary functions of an asphalt distributor is to spray asphalt. It evenly applies asphalt to the road surface, ensuring the thickness and uniformity of the asphalt layer meet design requirements. During the spraying process, the asphalt distributor can adjust the spraying speed and volume according to actual needs to meet varying road conditions and construction requirements. Furthermore, asphalt distributors are equipped with advanced control systems that precisely control the amount of asphalt sprayed, avoiding waste and pollution.
2. Asphalt Paving: Smooth and Dense Paving, Improving Road Performance
After spraying asphalt, asphalt distributors can also perform asphalt paving. It quickly spreads the asphalt sprayed on the road surface and, through vibration or rolling, makes the asphalt layer denser and smoother. This step is crucial for improving the road’s smoothness, density, and skid resistance. The asphalt spreader’s laying process ensures that the asphalt layer is tightly bonded to the base layer, forming a complete pavement structure.

The function of slurry seal is to use appropriately graded stone chips or sand, fillers (cement, lime, fly ash, stone powder, etc.) and emulsified asphalt, admixtures and water, and mix them in a certain proportion to form a flowing asphalt mixture, which is evenly spread on the road surface to form an asphalt seal. This seal is mainly used for roads in rainy areas, especially when the gaps in the asphalt surface layer are large and easy to seep water, the slurry seal can effectively solve this problem.
In addition, after the base layer is laid, if the asphalt surface layer cannot be laid in time and traffic needs to be opened, the slurry seal also plays a key role. It can temporarily close the road surface to prevent rainwater from penetrating, while protecting the base layer from damage. The slurry seal has strong fluidity and can better adapt to various road conditions to ensure construction quality and efficiency.
Compared with the viscous seal, the slurry seal has higher adaptability and flexibility. Due to its poor fluidity, the viscous seal is more difficult to spread evenly during construction, and it is more likely to flow in a humid environment, affecting the construction effect. The slurry seal, due to its strong fluidity, can better cover the entire road surface and ensure the uniformity and integrity of the seal.
In practical applications, the slurry seal also has the advantages of fast construction speed and low cost. Due to its good fluidity, less equipment and manpower are required during construction, which greatly shortens the construction period. In addition, the material cost of the slurry seal is relatively low, which effectively controls the overall construction cost.
Therefore, when choosing the seal material, the slurry seal has become a more ideal choice due to its excellent performance and economy. Whether it is for road maintenance in rainy areas or for base protection, the slurry seal can play an important role in ensuring the safety and service life of the road.

How to reduce energy consumption of emulsified asphalt machinery is a concern of many users and many manufacturers. Therefore, today, Sinosun Company, as a manufacturer of emulsified asphalt equipment, would like to take this opportunity to share with you the method of reducing energy consumption of emulsified asphalt machinery.
Since emulsified asphalt appears as a finished product in emulsified asphalt machinery, and the outlet temperature of ordinary emulsified asphalt is about 85℃, and the outlet temperature of emulsified modified asphalt is above 95℃, there is a lot of latent heat in emulsified asphalt, but the emulsified asphalt equipment does not make good use of them, but directly enters the finished product tank, allowing heat to be lost at will, resulting in energy waste.

The advantages of Sinoroader bitumen decanter equipment over similar domestic equipment are reflected in the following points:
1. The equipment produces 8-10t/hour, with an automatic telescopic sealed container structure. It uses an electric hoist to lift the asphalt barrel at the inlet guide tube. Start to control the hydraulic cart forward button, which will promote the barrel push (push and slide into the barrel). It is a 1300mm hydraulic cylinder with a 7.5-ton top thrust. The device has a beautiful appearance, reasonable layout, compactness, stable performance, and is suitable for production under various industrial and mining conditions.
2. Fast barrel removal: According to the principle of layered heating, it adopts four-layer thermal oil heating technology, a single inlet and outlet, and high thermal efficiency of heating; at the same time, it uses the waste heat of combustion gas for two heatings and efficient use of energy; the barrel body uses high-quality rock wool insulation material.
3. Good environmental protection: closed structure, no pollution.
4. No barrel hanging: The upper part of the asphalt barrel is hot, and each is directly affected by the thermal oil heating pipe. The barrel wall directly receives the heat dissipation of the heating coil, and the barrel is clean and fast, which will not cause waste of asphalt barrel hanging.
5. Strong adaptability: Suitable for imported and domestic barrels, and the deformation of asphalt barrels will not affect production.
6. Good dehydration: Use a large-displacement asphalt pump for internal circulation, stirring, water vapor overflows, and is naturally discharged from the exhaust port. After dehydration, asphalt can be directly used to produce asphalt mixture or used as matrix asphalt.
7. Automatic slag removal: This set of equipment has an automatic slag removal function. The filter device sets the asphalt circulation pipeline through the filter, which can automatically remove the barreled asphalt slag.
8. Safe and reliable: The equipment adopts an automatic control system, an automatic ignition burner import, can automatically control the temperature according to the temperature, and is equipped with corresponding monitoring instruments.
9. Convenient relocation: The whole machine is assembled with large components, which is easy to move and quick to assemble.
