Abstract

Asphalt fiber synchronous surface dressing has good stress absorption and dispersion ability. It has a network winding structure, which can effectively absorb, diffuse and redistribute the local concentrated stress in the pavement structure, and effectively reduce the stress in the pavement structure. Asphalt fiber synchronous surface dressing reduces the generation of cracks in the pavement structure layer, and prevents and suppresses the occurrence of reflection cracks. For three consecutive years, Qingyang highway development center of Gansu Province has applied asphalt fiber synchronous surface dressing in the managed and maintained trunk highway, which has effectively improved the traffic condition of the pavement, extended the service life of the highway and achieved good results.
