重载交通柔性基层沥青路面的抗车辙性能

沥青稳定碎石柔性基层能避免半刚性基层反射裂缝等病害,但抗车辙性能是制约其广泛应用的因素.通过对重载交通条件下柔性基层沥青路面的抗车辙性能进行系统研究,以及对抗车辙能力等路用性能的检验,得出半刚性基层和柔性基层沥青路面车辙深度相差不大,柔性基层沥青路面没有明显早期损坏,具有良好的抗车辙性能.

Pavement Rut Resistance of Asphalt Pavement with Flexible Base under Heavy Traffic

The asphalt stabilized macadan flexible base layer can avoid the reflection cracks of semi-rigid base, but rutt resistance constrains its widespread adoption. Through systematic study of the rut resistance performance of asphalt pavement with flexible base and test on its ability against rut under heavy traffic conditions, this paper indicates that there is no too much difference between rut depth of asphalt pavements with semi-rigid base and flexible base, flexible asphalt pavement has no obvious early damage and good rutting resistance.
