Application of Basalt Fiber Synchronous Surface Dressing Technology in Highway Maintenance in Qingyang Area

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