Asphalt sealant for roads, asphalt sealant

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.

4. Construction steps
Crack assessment: Use measuring tools to assess the width, depth and length of the cracks in order to select the appropriate particle size and type of asphalt caulking glue.
Crack preparation: Remove debris, dust and oil from the cracks to ensure that the inside of the cracks is dry and clean. For wider cracks, a slotting machine can be used to slot the cracks to increase the bonding area of ??the caulking glue.
Heating asphalt caulking glue: Place the asphalt caulking glue in a heating device and heat it to a suitable construction temperature (usually 180~220℃) to ensure that the glue can be fully melted and meet the construction requirements.
Crack filling: Use a caulking gun or caulking machine to evenly inject the heated asphalt caulking glue into the cracks, maintain appropriate speed and pressure, and ensure that the caulking glue can fully penetrate into the cracks and fit tightly to the road surface.
Finishing and compaction: Before the caulking glue cools, use a scraper or other tool to scrape the surface of the caulking glue flat, and use a roller or other compaction equipment to compact the caulking glue to ensure that the glue is tightly bonded to the road surface.
Maintenance: After the construction is completed, the repaired area should be maintained to prevent vehicles and pedestrians from passing through before the caulking glue is completely cured. The maintenance time is generally determined by the ambient temperature and the type of caulking glue.
5. Market situation
With the continuous development of road construction and maintenance, the market demand for asphalt caulking glue continues to grow. There are many companies producing and selling asphalt caulking glue in the market, with a wide range of products and different prices. At the same time, with the continuous advancement of technology and the continuous optimization of products, the performance and construction process of asphalt caulking glue are also constantly improving and improving.
6. Precautions
During the construction process, the safety operating procedures and traffic control measures should be strictly followed to ensure construction safety.
During construction, the ambient temperature and construction temperature should be strictly controlled to avoid affecting the construction quality.
After the construction is completed, the quality of the caulking should be checked to ensure that the caulking glue is firmly bonded to the road surface and there are no cracks, hollows and other problems.
In summary, asphalt caulking glue is an important road repair material with broad application prospects. During the construction process, the construction steps and requirements should be strictly followed to ensure the quality and safety of the construction.

    Bitumen decanter equipment can be placed in a complex system as an independent unit, replacing the existing heat source de-barreling method, or in parallel as a core component of a large set of equipment, or it can work independently to meet the requirements of small-scale construction operations.
    The Sinoroader bitumen decanter device is mainly composed of a de-barreling box, a lifting mechanism, a hydraulic thruster and an electrical control system. The box is divided into two chambers, the upper chamber is a barreled bitumen melting chamber, and heating coils are evenly distributed around it. The heating pipe and the bitumen barrel mainly exchange heat in a radiation manner to achieve the purpose of bitumen de-barreling. Several guide rails are the tracks for the bitumen barrel to enter. The lower chamber is mainly to continue heating the bitumen removed from the barrel to make the temperature reach the suction pump temperature (100℃), and then the asphalt pump is pumped into the upper chamber. At the same time, an empty barrel is pushed out at the rear end outlet. There is also an oil tank on the platform at the entrance of the asphalt barrel to prevent the dripping bitumen from flowing out.
    The inlet and outlet doors of the device adopt a spring automatic closing mechanism. The door can be automatically closed after the asphalt barrel is pushed in or out to reduce heat loss. A temperature gauge is installed at the asphalt outlet to observe the asphalt outlet temperature. The electrical control system can control the opening and closing of the hydraulic pump and the reversing of the electromagnetic reversing valve to realize the advance and retreat of the hydraulic cylinder. If the heating time is extended, a higher temperature can be obtained. The lifting mechanism adopts a cantilever structure. The bitumen barrel is lifted by an electric hoist, and then moved horizontally to place the bitumen barrel on the guide rail. A temperature gauge is installed at the outlet of the asphalt meltering equipment to observe its outlet temperature.

    In modern highway maintenance work, how to repair asphalt pavement quickly and effectively has become one of the key issues. As an advanced repair technology, cold patching technology is very popular because of its convenient construction and remarkable effects.
    What is the cold patching process?
    Cold patching process, as the name suggests, refers to a technical method for repairing asphalt pavement without heating. This process uses a specially proportioned cold-patch asphalt mixture. This material can maintain good fluidity and adhesion even at lower temperatures, thus ensuring the quality of the repair.
    Advantages of cold patching process
    Fast construction: Cold patching materials can be directly applied to damaged areas without preheating, and are immediately open to traffic, greatly shortening repair time.
    All-weather construction: Whether in hot summer or cold winter, cold patching materials can be effectively constructed and are not affected by the weather.
    Easy to operate: Thanks to its good working properties, even small damaged areas can be repaired easily.
    Environmentally friendly: The construction process reduces environmental pollution and is in line with the concept of green construction.
    Application scenarios
    The cold patching process is suitable for various types of pavement repair work, especially those places where traffic needs to be restored quickly, such as urban main roads, highway ramps, etc. In addition, the cold patching process is also an ideal choice for remote areas or situations where professional heating equipment is lacking.
    In short, the cold patching process has occupied a place in the field of rapid repair of asphalt pavement with its unique advantages and has become an indispensable part of modern highway maintenance.
