Is it better to use asphalt or glue for joint filling?

At present, the glues for pavement treatment include pavement hot-melt joint filling glue, epoxy resin cold repair glue, and joint filling asphalt.

Hot-melt joint filling adhesive is synthesized by adding calcium powder, titanium dioxide, and anti-low temperature stabilizer, plasticizer and anti-aging agent. The effect is that the tires do not stick in summer and do not crack in winter.

The pursuit of quality is of course better with potting glue, and the details can be learned about Hunan Xiangtan Hongxing Highway Materials.

For joint filling, it is personally recommended to use joint filling glue.

Because, when I used ordinary asphalt last year, it fell off in less than three months, and then I switched to Jiage joint filling glue, which does not flow in summer and does not crack in winter, and has strong adhesion. Hope my personal experience can help you!

Dealing with cracks. Use a high-pressure hair dryer to clean up the dust and other debris on the cracked part of the asphalt pavement, and if there is standing water, the water should be sucked out and dried before construction.

2.Stir the caulk.

Open the package, fully stir the caulk with machinery or wooden sticks, pay attention to stirring up all the sediment at the bottom of the packaging barrel, because the Tazhong Highway reconstruction project is to repair the cracks in winter, so the fluidity of the material is increased in the mixing process, and the trial construction process is more convenient.

3.Construction method.

For cracks with small crack width, the stirred joint patch is directly poured into the funnel and the asphalt pavement cracks are poured; If the width is more than 15mm, an appropriate amount of aggregate should be added to the material and stirred evenly before filling.

Summary. Depending on the size of the gap, small gaps can be made of ointment, polyvinyl chloride, coal tar and other materials, while asphalt is used for larger cracks. However, the performance and service life of these two can no longer meet the needs.

It is recommended to use the upgraded version of asphalt grout adhesive, which is a high polymer, which is very good in terms of road usability and high and low temperature performance.

Grout is a common pavement maintenance measure that can repair small cracks and water seepage and pollution problems on the pavement. In the process of caulking, we usually use asphalt materials.

Bitumen is a dark brown semi-solid or solid substance that is resistant to deficiency by separating and refining petroleum, coal tar, natural gas and other substances. Due to its excellent adhesion, elasticity and durability, it is widely used in road construction, maintenance and maintenance, including detailing work such as grouting. In asphalt, the commonly used types are petroleum asphalt, modified asphalt and asphalt emulsion, etc., among which the choice of which asphalt type of grouting depends on the material of the road and factors such as the environment.

Grout is an important measure in pavement maintenance work, improving the bearing capacity and durability of the road by filling in the small cracks, joints and potholes in the pavement. In this process, the use of asphalt as a filler material is very effective to take full advantage of the excellent adhesion and elasticity of asphalt, fix the road surface material and prevent leakage, water erosion, ignition or other damage in these areas. In addition, asphalt materials can be well adapted to the environment and materials of different types of roads, such as stone asphalt is suitable for highways, urban roads and other roads with large traffic flow, while modified asphalt is suitable for roads with drastic temperature changes or small traffic flow.

In conclusion, the use of asphalt materials in joint filling is an effective method of pavement maintenance. Different types of asphalt materials need to be selected for different pavement environments and materials, and the use of suitable asphalt materials can ensure the quality of road maintenance and maintenance effects. <>
