Road Asphalt Crack Filler: Year-Round Protection – High Temperature Resistance and Low Temperature Resistance

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 synchronous chip seal truck is a specialized vehicle capable of simultaneously and precisely applying asphalt binder and aggregate to the road surface. Its core value lies in “synchronization”—the asphalt and aggregate contact and bond almost instantaneously, forming an initial interlocking structure. Compared to traditional step-by-step construction, this process significantly improves the asphalt’s coating effect and bonding strength on the aggregate, resulting in a denser, more wear-resistant, and skid-resistant seal.
Its main functions include preventative maintenance (such as treating minor cracks and preventing water damage), corrective maintenance (improving road surface skid resistance), and serving as a stress-absorbing or wearing course layer for newly constructed roads. Understanding its working principle and application scenarios is a prerequisite for scientific procurement and use.
Working Principle Revealed: Like a “road doctor,” it simultaneously sprays asphalt binder and aggregate to form a robust, waterproof, and skid-resistant layer, extending road surface life and making driving safer!
Key operational points to remember: Before construction, check the equipment condition to ensure the asphalt temperature matches the aggregate size; maintain a constant speed while driving, control the spray volume to avoid waste or insufficient application; clean up residue promptly after completion to prevent blockages.
Daily maintenance is essential: Regularly inspect the hydraulic system, spray boom, and aggregate bin, and replace worn parts promptly; take precautions against freezing in winter to prevent equipment damage.
The use of synchronous chip seal asphalt is a comprehensive undertaking that integrates mechanical knowledge, materials science, and construction technology. The organic combination of excellent equipment, qualified materials, and standardized operation enables synchronous chip seal technology to truly provide roads with a durable and reliable “protective layer,” achieving innovative economic and social benefits.

Modified material bitumen stripper, if the definition is simple, is an bitumen stripper. If described in detail, modified materials such as rubber powder or other fillers are added to the bitumen stripper, or an bitumen stripper is used to Block chemical substances such as photooxygen catalysis. The first is to change the chemical composition of the bitumen stripper, and the second is to use modified materials to equip the stripper with a certain spatial network structure, thereby improving its performance. Modified bitumen strippers mainly include vulcanized rubber and thermoplastic polyurethane elastomer modified bitumen strippers, plastic and anti-corrosion coating modified bitumen strippers and polymer modified bitumen strippers.

Asphalt mixture is a general term for a mixture composed of aggregate and asphalt binder. Based on material composition and structure, it is categorized as continuously graded and discontinuously graded mixtures. Based on aggregate gradation composition and void ratio, it is categorized as densely graded, semi-open graded, and open graded mixtures. Based on nominal maximum particle size, asphalt mixtures can be classified as extra-coarse (nominal maximum particle size greater than 31.5mm), coarse (nominal maximum particle size equal to or greater than 26.5mm), medium (nominal maximum particle size 16mm or 19mm), fine (nominal maximum particle size 9.5mm or 13.2mm), and sand (nominal maximum particle size less than 9.5mm). Based on the manufacturing process, asphalt mixtures can be classified as hot-mix asphalt, cold-mix asphalt, and recycled asphalt.

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 thermal 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.

During the use of emulsified bitumen equipments, if maintenance is not paid attention to, the cycle will be short, and problems will often occur during use. Only by doing a good job of maintenance can the operation efficiency of the equipment be improved. For example, during maintenance, the following points must be grasped.
It is necessary to regularly check the wear condition of the internal structural components of the mechanical equipment, such as the core feed pipe, the rough jaw plate on the impeller, the cone cap, the wear level of the jaw plate, the rain shield on the circle, and the wear condition. If the wear is more serious, it is necessary to replace or repair it in time. When replacing, it is also necessary to pay attention to the model and specifications, and replace it according to the original components as a reference.

Abstract: Asphalt melting equipment is one of the indispensable equipment in modern road construction. Its main function is to heat a large amount of cold hard asphalt to a suitable working temperature at the construction site. Advanced asphalt melting equipment can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.

Except for the first application, for enterprises whose block asphalt melting equipment license has expired and continue to engage in the production and operation of block asphalt melting equipment, they should apply for the relevant matters of postponement and renewal 45 working days before the expiration of the license.
The block asphalt melting equipment should first prepare the block asphalt melting equipment application materials, and then submit an application for postponement and renewal to the municipal environmental protection bureau. According to the production and operation of the block asphalt melting equipment and environmental protection work of the applicant enterprise, the municipal environmental protection bureau of the district where the block asphalt melting equipment is located will provide a review opinion in the form of a public document.
For the block asphalt melting equipment, the Provincial Environmental Protection Department will review the application materials, and appoint the Provincial Block Asphalt Melting Equipment Management Office to organize relevant doctors to conduct technical evaluation and on-site technical evaluation, and produce expert technical evaluation opinions and on-site inspection reports. Then report the materials of the block asphalt melting equipment to the meeting of directors for scientific research and make a review decision.

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.

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.

As -20°C temperatures blanket northern China, an innovative practice integrating green materials and digital sensing is quietly reshaping highway maintenance in these areas. Industrial solid waste is being transformed into cold-resistant “smart patches,” which, combined with microchips embedded in the road surface, not only allow winter repairs to proceed smoothly but also mark a crucial step towards green and intelligent transportation infrastructure maintenance. This is not only a technological breakthrough but also a vivid illustration of the transformation of development methods.
It is understood that the core material used in this test is an environmentally friendly asphalt that “grows on solid waste.” Industrial solid waste such as fly ash and coal gangue account for 60%-65% of its raw materials. Through independently developed modification technology, it enables normal construction even in temperatures as low as -20°C.
“Traditional hot-mix asphalt requires temperatures of 130℃ to 160℃, while ordinary cold-mix asphalt basically stops working below 0℃. This new material breaks free from these temperature constraints,” explained on-site technicians. This not only solves the problem of road repair in cold regions during winter but also significantly reduces raw material costs—by 15%-20% compared to traditional materials, labor and energy costs are reduced by over 20%, and overall maintenance costs are reduced by approximately 20%-25%.
The repaired road surface can be opened to traffic 1-2 hours after compaction, reaches its design strength within 24 hours, and has a durability period of 3-5 years, three times that of ordinary cold-mix asphalt. This means that road “wounds” heal faster and more firmly, making repeated repairs a thing of the past.

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.

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.

Asphalt, a black, viscous mixture obtained through crude oil fractionation, is a key component of asphalt used in the construction of roads, streets, and other infrastructure. Modified asphalt is chemically engineered to deliver optimal performance, with increased resistance to permanent deformation, particularly in asphalt mixes used in challenging or heavily trafficked locations.

I believe that after a long period of contact with asphalt tanks, everyone knows that the working efficiency of emulsified asphalt equipment actually depends on the operator. The more experienced the operator is and the stronger his ability to deal with various emergencies is, the higher the working efficiency will be, and the safety will be guaranteed. Mastering more equipment-related knowledge is what every friend should pursue. Today, the editor will explain to you the details that need to be paid attention to when operating emulsified asphalt equipment:

In addition to being used according to regulations, modified bitumen equipment should also be maintained regularly in order to effectively extend the service life of modified bitumen equipment. The delivery pump of modified bitumen equipment, as well as its motor and reducer, need to be maintained in accordance with the specifications of the instructions. If the modified bitumen equipment is parked for a long time, the liquid in the tank and pipeline needs to be drained, and each moving component also needs to be filled with grease. The dust in the control box of the modified bitumen equipment needs to be cleaned once every six months. A dust blower can be used to remove dust to prevent dust from entering the machine and damaging parts. The micro powder machine needs to add unsalted butter once for every 100 tons of emulsified bitumen produced.

From the current point of view, road construction machinery has bottomed out and asphalt meltering equipment has risen rapidly. In recent years, highway construction and maintenance departments have a strong awareness of using asphalt mixing equipment, especially in developed coastal areas such as Beijing, Shanghai, Jiangsu, Zhejiang, etc. In addition, these regions have a fast economic growth rate, relatively developed industry, and strong comprehensive economic strength. Therefore, the consumption of asphalt mixing equipments in these regions has always been at the forefront of the country. With the rapid development of highway construction and the increase in demand for asphalt, barreled asphalt has been widely used for its convenient transportation and easy storage. In particular, most of the high-performance imported asphalt used in high-grade highways is in barrel form, which requires an asphalt meltering equipment with fast melting speed, clean de-barreling, and can prevent asphalt aging. my country’s highway construction has achieved remarkable results, among which mechanized production has contributed greatly. Different types of asphalt mixers and bitumen meltering equipment are selected for the characteristics of large highway pavement construction and tight construction period. With the rapid development of my country’s economy, the further extension of expressways, and the large-scale development of western construction, the central and western regions have become new investment hotspots. While paying attention to the market in the developed eastern regions, domestic road construction machinery manufacturers have also increased their efforts to develop the central and western markets, creating new highlights for the domestic asphalt mixing plants consumer market. In summary, my country’s asphalt mixing plant sales market has begun to move westward with the westward movement of investment hotspots. As the market center of gravity gradually shifts westward, the market in the western region is gradually heating up. The self-heating integrated structure, hot air barrel melting and bitumen barrel flipping technology in the asphalt barrel removal equipment are our company’s self-heating integrated structure. The thermal oil furnace used in the old equipment is perfectly integrated with the asphalt barrel removal equipment body, which reduces the volume of the entire set of equipment, greatly reduces equipment investment, saves equipment space and transfer transportation costs.

With the performance, the damaged part is restored in time to ensure the safety, comfort and smooth driving, saving transportation costs and time; Correct technical measures should be taken to improve the quality of the project, extend the service life of the road, and postpone the reconstruction time.

Cleaning the nozzles of an asphalt distributor truck typically follows these steps:
Preparation: First, ensure the asphalt distributor truck is stopped and turn off the relevant oil valves and power.
Activate Cleaning Mode: Turn the “Control Selection” switch on the rear control panel to “Background” and switch the “Asphalt Control Valve” to “On”. Next, turn on the “Asphalt Pump” switch and open the pipeline air valves (usually two).
Start Cleaning: Switch the “Asphalt Control Valve” to the “Nozzle Cleaning” position to start the automatic nozzle cleaning program. This will typically circulate the cleaning fluid (such as diesel) through the nozzles to remove residual asphalt. It is recommended to circulate twice to ensure thorough cleaning.

How to reduce the energy consumption of emulsified asphalt production equipment is a concern of many users, and is also an issue that many manufacturers attach great importance to. Therefore, today Sinoroader, as a manufacturer of emulsified asphalt production equipment, would like to take this opportunity to share with you how to reduce the production of emulsified asphalt. Equipment energy consumption method.
Since emulsified asphalt appears as a finished product in emulsified asphalt production equipment, and the outlet temperature of ordinary emulsified asphalt is about 85°C, the outlet temperature of emulsified modified asphalt is above 95°C, so there is a lot of latent heat in emulsified asphalt, but emulsified asphalt The production equipment does not make good use of them, but directly enters the finished product tank, allowing the heat to be lost at will, resulting in a waste of energy.

Precautions for checking emulsified asphalt equipment
Sinoroader emulsified asphalt pavement engineering common equipment, now has gradually been widely used.
We all know that before any equipment is used, the equipment should be preliminarily inspected to check whether the installation is normal, and then put into use. The use of modified asphalt modified asphalt production equipment can also extend the peak season. The modified asphalt and stone water machine can be mixed with wet stone to form a continuous film under the surface conditions of low-temperature asphalt and stone. The viscosity of the asphalt is low and the viscosity of the emulsified asphalt is low. Wet film below 10 degrees.

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.

There is a wide variety of asphalt melting equipment on the market, including different brands and models. The prices of these devices vary widely, depending mainly on factors such as their features, performance, and specifications.
Asphalt melter equipment produced by some large brands such as Sinoroader usually has higher quality and reliability, so the price is relatively higher. However, they also offer longer service life and better maintenance support.

Asphalt crack filling sounds technical, right? But it’s actually a common task in road maintenance. Whenever I see cracks on the road, I think about how, if these cracks aren’t treated promptly, rainwater and impurities will seep in, significantly shortening the road’s lifespan. So today, let’s talk about the correct method of asphalt crack filling to make the road surface more durable!
The Importance of Crack Filling Repair
Crack filling repair is more than just filling cracks. It’s a crucial step in preventing rainwater and impurities from penetrating the cracks, thus extending the road’s lifespan. Imagine if road cracks weren’t repaired in time; those tiny cracks would gradually widen, even leading to road damage and affecting driving safety. Therefore, the importance of crack filling repair is self-evident.
Steps for Cleaning and Filling Cracks

Synchronous sealing trucks play an important role in road maintenance. Daily maintenance of synchronous sealing trucks is an important part of ensuring the good operation of the equipment and extending its service life. Here are some common maintenance measures:

Synchronous seal pavers are crucial equipment in road construction, and their daily maintenance directly impacts construction efficiency and equipment lifespan. Mastering these maintenance points is key to extending the equipment’s service life.
First, daily inspection and maintenance are essential. Before each operation, check tire pressure and for foreign objects in the tread. Replace tires immediately if bulges or cracks are found. Also, check engine oil, hydraulic oil, and coolant levels, adding as needed to prevent overheating and damage. Regularly lubricate chains and drive components to prevent excessive friction and jamming, which can affect the accuracy of the synchronous seal.

Emulsified asphalt is an emulsion that disperses asphalt into the water phase to form a liquid at room temperature. This determines that emulsified asphalt has many technical and economic advantages over hot asphalt and diluted asphalt. We know that modified asphalt equipment is a road engineering machinery. In order to better promote users’ understanding of it, today the editor will introduce its characteristics to you so that users can better understand that modified asphalt equipment is used for modified asphalt. It consists of a main machine, a modifier feeding system, a finished product tank, a heat transfer oil reheating furnace and a microcomputer control system. The main machine is equipped with a mixing tank, a dilution tank, a colloid mill and an electronic weighing device. The entire production process is controlled by a computer automatic program. In addition, it can be learned that the product has the advantages of reliable quality, stable performance, accurate measurement, and convenient operation. It is an indispensable new equipment in highway construction. The advantages of asphalt equipment are prominently reflected in its two-way modification effect, that is, while greatly increasing the softening point of asphalt, it also significantly enhances the low-temperature ductility, improves the temperature sensitivity, and has a particularly large elasticity and recovery rate. The modified asphalt equipment has a long service life and a safe and reliable production process. The rotor and stator are specially heat treated, and the service life of the equipment is more than 15,000 hours.
