Pavement conservation applications from quangongzi's blog

The purpose of the chip cover is to increase the service life of the road. Pavement maintenance application of stone crust, in the field do not need to limit the asphalt mixing equipment, while the use of stone chip cover the road surface does not appear reflective cracks and micro cracks, to prevent the road further aging and flooding damage. In the United States, it is documented that at the grassroots level, the life of the pavement can be increased to more than 10 years. Fill the cracks and bridge repair, for emulsified asphalt, the addition of polymer to increase the cost of bonding materials (or even more than twice), but it can significantly extend the life of the road, the Australian institutions found that: Method to design and rebuild the rural road, can damage the more serious road life increased by 10 to 15 years. The reflection of cracks on the road for processing, but also can increase the service life of the road 5 to 8 years.Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery

The stone crust is a thin layer of high asphalt that covers the surface, but this layer is flexible and wear resistant. Addition of polymer can increase the adhesion, adhesion, wear resistance and road surface crack resistance. This allows the sebace cover to be used both for road maintenance and for road reconstruction, especially in road resistance. In addition, the use of SBR or SBS modification can be carried out road cover and bridge crack repair, it is particularly important to reduce the reflection cracks on the road. As the emulsion has excellent moisture resistance, chemical adhesion and emulsifier system and the maintenance of the road maintenance properties, so the emulsion is more suitable for road spread. According to the weather and traffic conditions, the road when the cloth requires better traffic control and better sealing conditions.
