摘要
组合式基层沥青路面能有效避免沥青路面产生结构性疲劳开裂。我国对于沥青路面承载能力和抗车辙能力在重载交通下的适应性,尚无长期性研究定论。在某典型组合式基层沥青路面和半刚性沥青路面结构受力特征分析基础上,结合实体工程进行了长期性能跟踪观测,对其路面车辙与裂缝发展趋势进行了分析。
Combined base asphalt pavement can effectively avoid structural fatigue cracking. However, there is no long - term research conclusion on the bearing capacity of asphalt pavement and the adaptability of anti - rutting capability under heavy traffic in our country. In this paper, the pavement rutting and crack development trend were analyzed, basing on one typical combined base asphalt pavement and analysis of mechanics characteristic of semi -rigid asphalt pavement, and combining with the long - term performance tracing observation of the field test project.
