公路沥青路面预防性养护材料的试验及应用研究核心探究

沥青路面在使用过程中,常常出现沥青松散、微裂缝、路面老化等病害,不仅影响交通安全,也降低了路面的使用寿命。因此,非常有必要对沥青路面进行预防性养护。本文将阐述通过掺量试验与RTFOT老化试验,研究预防性养护材料对沥青各项性能的影响,以及在实践中如何应用预防性养护材料。

Research on the core of test and application of preventive maintenance materials for highway asphalt pavement

During the use of asphalt pavement, there are often problems such as loose asphalt, micro cracks and aging of pavement, which not only affects traffic safety, but also reduces the service life of pavement. Therefore, it is very necessary to preventive maintenance of asphalt pavement. This article will describe the effects of preventive maintenance materials on asphalt performance through the blending test and the RTFOT aging test, and how to apply preventive maintenance materials in practice.
