Synchronization asphalt chip seal technology mainly has the following advantages
1 ) synchronous pavement surface is smooth asphalt binder low energy technology into primary surface micro cracks , plays the role of a good seal seam .
2 ) synchronous pavement surface is essentially rely on a certain thickness of asphalt membrane (1-2 ) bond Treatment thin layer of asphalt macadam surface , the overall mechanical characteristics are flexible, can increase the performance of pavement crack , crack cure road network turtle reduce reflective pavement cracks , water seepage improve pavement performance for road maintenance to extend the life of the road for more than 10 years , if the use of polymer modified asphalt, high viscosity asphalt rubber binder better.
3 ) As a new layer of semi-rigid asphalt pavement sealing water , not only have excellent sealing effect of water , but also reflective cracking semi-rigid base of a significant delay effect.
4 ) synchronous pavement surface can greatly improve the original road surface friction coefficient , an increase of pavement skid resistance and surface flatness can be a certain degree of recovery .
5 ) through the use of local construction methods of multi-layer paving stones of different size , synchronization chip seal layer can effectively cure more deep ruts, subsidence and other diseases , and this is the general conservation methods can not match.
6 ) synchronous pavement surface can be used as transitional low-grade highway pavement , highway construction funds to alleviate the serious shortage of contradictions.
7 ) synchronous chip seal process is simple , fast construction , real time traffic speed open .
8 ) Whether used for road maintenance or as a transitional road , price-performance synchronous chip seal layer is superior to other methods at the table , thereby greatly reducing the cost of repair and maintenance of roads .
