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.

Improve the reliability of SBS bitumen emulsion plants: Once you have an established maintenance, it will help to identify problems. This will allow the maintenance plan and time to be carried out at your convenience. Regular maintenance will increase the normal operation time of SBS bitumen emulsification equipment, and it can be used when necessary. Low cost of operation: Imagine an SBS bitumen emulsification plant breaks down during a project. With a protective maintenance plan, such things happen less often because you have taken good care of the SBS bitumen emulsification plant.
If the SBS bitumen emulsification plant wants to maintain normal operation, then in the production process. All stages need to be maintained normal, among which the normality of the circuit system is an important aspect to ensure its smooth operation. Imagine that if there is a problem with the circuit during the on-site operation, it may affect the development of the entire project.
For users, of course, they don’t expect this to happen, so if the SBS bitumen emulsification plant is in the work of using the SBS bitumen emulsification equipment, if there is a circuit problem, it is necessary to take appropriate measures to solve it in time. The following article will give a detailed description of this problem, and the following SBS bitumen emulsification plant can be of benefit to everyone.

The container-type emulsified bitumen equipment hot-melts the base cold-mix colored bitumen and disperses it through the equipment into small cold-mix colored bitumen particles in an aqueous solution containing emulsifier to form a liquid cold-mix colored bitumen material.

1. Observation: Pay attention to the dynamics of the road surface after milling (three to four days), and pave the milled and roughened road surface in time when paving conditions are met.
2. On-site mixing: During construction and production, a sealing slurry truck should be used for on-site mixing. Through the metering equipment of the sealing truck and on-site operation by a robot, it is ensured that emulsified asphalt, water, mineral materials, fillers, etc. can be mixed according to a certain proportion. , stir through the mixing box, and the paving thickness is not higher than the roughing depth.

Preparation items for micro-surfacing slurry sealing: materials, construction machinery (micro-surfacing paver) and other auxiliary equipment.
The micro-surface slurry seal requires emulsified asphalt and stone that meet the standards. The metering system of the micro-surfacing paver needs to be calibrated before construction. The production of emulsified asphalt requires asphalt heating tanks, emulsified asphalt production equipment (capable of producing asphalt content greater than or equal to 60%), and emulsified asphalt finished product tanks. In terms of stone, mineral screening machines, loaders, forklifts, etc. are needed to screen out oversized stones.
The tests required include emulsification test, screening test, mixing test and the equipment and technical personnel required to do these tests.

The viscosity of the bitimen melter equipment decreases as the temperature increases during the production process. Its output viscosity is about twice as high as every 12°C increase. During production, the base bitimen melter equipment must first be heated to a liquid state and then emulsified. In order to better integrate the emulsification ability of colloid milling, the viscosity of base bitimen melter is generally controlled to be about 200 cst. The lower the temperature, the higher the viscosity, which increases the pressure on the bitimen melter pump and colloid milling, making emulsification impossible: However, on the other hand, in order to prevent the asphalt debarrel equipment from weaning when the moisture of th

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.

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.

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.

The difficulty of emulsified bitumen equipment itself, because general bitumen also has different classifications, in the production and processing of emulsified bitumen equipment bitumen concrete, it is necessary to pay attention to whether the common raw materials are the common bitumen and ensure the quality. Check the black antistatic tweezers of emulsified bitumen equipment asphalt concrete machine equipment emulsified bitumen equipment.
If the gap of the black antistatic medical tweezers bitumen concrete micro-powder machine of emulsified bitumen equipment is enlarged after long-term use, then we can adjust it and continue to process it. Emulsified bitumen equipment is a relatively simple difficulty.

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

Asphalt emulsifiers can be divided into synthetic emulsifiers, natural emulsifiers, inorganic powder emulsifiers, etc. according to their formation. Synthetic emulsifiers are currently the most widely used. Asphalt emulsifiers are a type of organically synthesized surfactant that can emulsify asphalt.
Emulsifiers are divided into ionic and non-ionic types according to whether the hydrophilic group of the emulsifier molecule is charged when the emulsifier is dissolved in water. Ionic emulsifiers are divided into cationic and anionic types due to the different charges of the hydrophilic group after ionization in water. In addition, there are zwitterionic types.
Cationic emulsifiers are divided into three types: fast cracking, medium cracking, and slow cracking according to the speed of demulsification. Slow cracking emulsifiers are divided into slow setting and fast setting according to the length of time the mixture solidifies. Slow cracking and slow setting types are mainly used as permeable oils. Slow cracking and fast setting are used for micro-surfacing, slurry sealing, cold regeneration, etc. Medium cracking and fast cracking types are used for adhesive layer oils, gravel sealing layers, and waterproof base oils.

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.

Asphalt is widely used in road construction, primarily for paving. Its advantages include the following:
Good adhesion: It bonds firmly with aggregate, tightly binding aggregate particles together to form a stable pavement structure that effectively resists damage from vehicle loads and natural factors.
Good waterproofing: Asphalt is impermeable, preventing rainwater from penetrating the pavement structure, protecting the roadbed and base layer from water erosion, and extending the service life of the road.
High smoothness: The paved road surface has good smoothness, providing a smooth driving surface for vehicles, reducing bumps and vibrations during driving, and improving driving comfort.
-Excellent skid resistance: Through the appropriate selection of aggregates and mix design, asphalt pavements can achieve excellent skid resistance, ensuring sufficient friction for vehicles in both wet and dry conditions, ensuring safe driving.
Easy to repair: Local damage is easy to repair, and can be repaired using hot or cold patching methods. The repaired pavement adheres well to the original surface and can be quickly restored to service. Convenient Construction: Asphalt pavement construction is relatively simple and can be quickly paved using mechanical equipment such as pavers. Traffic can be reopened relatively quickly after construction, minimizing impact on traffic.
Good Noise Reduction: Compared to cement concrete pavement, asphalt pavement effectively absorbs vehicle noise, reducing traffic noise pollution and improving the surrounding environment.

As a black road construction machinery, the synchronous chip sealer is the main equipment for highways, urban roads, airports, and port terminal facilities. Do you know what kind of synchronous chip sealer? What products do you have to choose from?
Asphalt dispensers are classified according to the purpose, operation mode, and drive mode of the asphalt pump. According to the purpose, asphalt dispensers can be divided into two types: road use and road construction use. The asphalt tank capacity of the asphalt dispenser used for road construction generally does not exceed 400L, while the asphalt tank capacity of the asphalt dispenser used for road construction is 3000-20000L.

From three aspects, emulsion bitumen equipment has good economic performance:
First, energy saving. The kerosene or gasoline content in diluted asphalt can reach 50%, while the emulsion bitumen plant only contains 0-2%. This is a valuable saving behavior in the production and utilization of white fuel. By simply increasing the viscosity standard of asphalt by adding light oil solvent, asphalt can be poured and spread, and it is hoped that the light oil after use can evaporate into the atmosphere.
Second, versatility. There are many application methods for emulsion bitumen plants, and the appropriate method needs to be selected when applying it. The same emulsion can be used for large-scale sealing and can be used for small-scale pit repair work. Because they can be stored in tanks for a long time, they are very easy to use when applied in remote areas.
Third, it is easy to use. The professional spreading of emulsions requires professional equipment, such as spreaders. Small-area emulsion applications can be directly poured and spread by hand, such as small-area pit repair work, crack fillers, etc. Small quantities of cold mixes only require basic equipment.

Emulsified asphalt is an aqueous suspension of asphalt particles with high interfacial energy. This suspension state is thermodynamically unstable and has the potential to reduce its interfacial area (i.e., through the coagulation process) to a stable state. Preventing this coagulation state (dispersion destruction) is the stabilization effect of the emulsifier protective layer. The stability of emulsified asphalt refers to the ability of asphalt particles to aggregate and cause phase separation, and also refers to the time required for emulsified asphalt to reach equilibrium. That is, the time for asphalt particles to aggregate and separate from water. How can we increase this time? How to prevent emulsified asphalt from demulsifying?

Emulsified asphalt equipment is a special equipment for producing emulsified asphalt. The emulsified asphalt produced by emulsified asphalt equipment is used in many industries. I wonder how much you know about the emulsified asphalt produced by emulsified asphalt equipment. Let’s take a look at them one by one:
Slurry seal is a cold mix asphalt mixture with the advantages of aggregate and asphalt mixing. Under normal circumstances, similar graded slurry seal has a higher modulus than hot mix asphalt mixture, so it is often used to fill road rutting. The higher stability has a higher resistance to deformation. The mixture is usually composed of harder fine aggregate grading and wear-resistant aggregate with high sand equivalent, especially micro-seal and polymer-modified seal. This greatly increases the strength and integrity of the road surface. This makes the road surface have high wear resistance and excellent deformation resistance. Emulsified asphalt emulsion is also easy to use on a mobile slurry seal paver, where mixing and admixtures are used for chemical control to meet maintenance needs.

When performing bitumen melting, specialized equipment is required. These equipment usually include bitumen melting furnaces, asphalt mixers, asphalt conveying equipment, etc. Among them, the bitumen melting furnace is one of the most advanced equipments, which can heat solid bitumen to liquid state. In addition, asphalt mixers can mix liquid asphalt with stone to make asphalt concrete. , Asphalt conveying equipment can transport asphalt concrete to the construction site. The selection and use of these equipment are of great significance to ensure the quality of bitumen melting and construction efficiency.

This set of mechanical equipment includes wastewater treatment, water storage tank, automatic water measurement and verification temperature control system, asphalt storage tank, asphalt external temperature system, hot water pump soap condiment system, soap storage tank, soap mixing pump, soap external It is composed of temperature system and measurement verification system, filtration system, hot asphalt mixing pump and measurement verification system, three-stage pipeline-type black antistatic medical tweezers, emulsified asphalt cooling system and retrieval machinery, and automatic control system for commercial tanks and electrical equipment.

Classification analysis of emulsion bitumen equipment is used to heat-melt bitumen. According to the actual cutting effect of mechanical equipment, it is loosened into a solution with demulsifier in the form of tiny droplets to form oil-in-water asphalt. Industrial equipment for lotions. Emulsion bitumen equipment can be divided into three types: portable, transportable and mobile according to the equipment, layout and maneuverability of the equipment.

Modified bitumen equipment uses modified bitumen colloid mill. Its blade has high hardness, high linear speed of the moving disk, and the gap can be adjusted to 0.15mm. It is suitable for processing various polymer-modified bitumens, such as SBS, PE, EVA, etc.

Changing the color of asphalt pavement is an important project aimed at improving the beauty of roads, optimizing traffic signs and enhancing urban landscape effects. The following is a detailed introduction to the color change of asphalt pavement:
1. Color change method
Using pavement color change spray:
Spray directly on the original asphalt pavement surface to make the road surface look brand new.
This method is simple and fast to construct, with bright and lasting colors, and will not change the structure of the pavement.

For users of equipment, the amount of material used is the focus of every user. We should attach great importance to this link in the production process. The following is an analysis of the amount of emulsifier used by Gaoyuan manufacturers.
When emulsified asphalt equipment is emulsifying asphalt, the asphalt temperature is better controlled at above 130°C to have better fluidity; 2. The amount of emulsifier is generally 8-14‰ of emulsified asphalt, that is, 8-14kg per ton of emulsified asphalt (asphalt content is more than 50%), and the temperature is 60-70°C. The emulsifier should be used in the middle and upper limit of the production, 10 kg per ton of emulsified asphalt, or 20 kg per ton of water (asphalt content is 50%); the amount of BE-3 emulsifier is generally 18-25‰ of emulsified asphalt, that is, 18-25kg per ton of emulsified asphalt (asphalt content is more than 50%), and the emulsifier solution temperature is 60-70°C. The emulsifier should be used in the upper and middle limits in the first production to ensure successful production. Use 24 kg per ton of emulsified asphalt, or 48 kg per ton of water (asphalt content is 50%). After the production goes smoothly, the dosage can be reduced according to actual conditions.

In the application, the asphalt spreader has intelligent asphalt spreading rate and low investment, low power consumption, low cost, high thermal efficiency. The asphalt spreader can reach the temperature required for construction in a short time. It is easy to use and move. It can be operated by one person. A set of electric heaters is a bit expensive. In the production process of the asphalt spreader, water, as a production material, needs to be heated from room temperature to about 55°C. The evaporation heat of the asphalt spreader is transferred to the drainage. It is found that after the emulsified asphalt is produced for 5 tons, the asphalt spreader is accompanied by a significant increase in the temperature of the cooling circulating water. The production water uses cooling circulating water, and the water basically does not need to be heated. It can save 1/2 of the fuel simply from the energy.

△ The Role of Penetrator
The role of penetrator is to create a good bond between the asphalt surface layer and the non-asphalt base layer. By spraying penetrator onto the base layer, it penetrates deeply into the base layer, strengthening the bond between the surface layer and the base layer, thereby ensuring the quality of the pavement. Penetrator sprays deeply into the base layer, strengthening the bond between the surface layer and the base layer, ensuring construction quality. This step is essential before paving the asphalt surface layer.
△ The Role of Tack Coat
The role of tack coat is to form a thin film of adhesive on the interface between existing structures, curbs, manholes, and other structures and the asphalt mixture layer. Spraying tack coat strengthens the bond between the asphalt layers and also improves the bond between the asphalt layers and the cement concrete pavement. This step is crucial to ensuring the quality of pavement construction. Tack coat forms a thin film on the structural interface, strengthening the interlayer bond and improving construction quality.

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.
