Asphalt pavement crack treatment: technological innovation a

Asphalt pavement cracks are one of the most common phenomena in road diseases. Their occurrence not only affects the aesthetics of the road and the comfort of driving, but also, if not treated in a timely manner, can further damage the pavement structure and increase maintenance costs. Therefore, the treatment of asphalt pavement cracks has become an important issue in road maintenance and managem

Asphalt pavement crack treatment: technological progress and

As the main pavement type of high-grade highways in China, the durability and safety of asphalt pavement are directly related to the operation status and traffic efficiency of the highway. However, cracking is one of the common diseases of asphalt pavement, which not only affects the comfort of driving, but may also lead to further damage to the pavement structure. Therefore, the treatment of asph

Reasons for crack formation and corresponding maintenance

Cracks are mainly divided into: 1. Structural damage cracks caused by the action of driving loads; Temperature cracks caused by temperature changes in the asphalt surface layer, including non load cracks such as low-temperature shrinkage cracks and temperature fatigue cracks. Domestic and foreign studies have shown that the reflection cracks of semi-rigid base asphalt pavement correspond to non lo

Classification of road rollers

Due to the gravitational force of the machinery itself, it is suitable forStatic pressure rollerVarious compaction operations cause permanent deformation and compaction of the compacted layer. It is divided into two types: steel wheel type and tire type.The roller structure includes light rollers, groove rollers, and sheep foot rollers. The most common application of polishing is mainly for road u

Treatment plan for asphalt pavement cracks

Treatment plan for asphalt pavement cracks1. SlottingUse a slotting machine to track and slot along the crack.2. Clean the seamsUse a dust blower to blow and clean the opened slots.3. Heating and dehumidificationUse a hot air spray gun to remove moisture and heat the seam wall.4. Grouting seamUse asphalt sealing equipment for joint sealing.
