组合式沥青路面结构特性研究

Research on Characteristic of Combined Asphalt Pavement Structure

在半刚性底基层上铺设级配碎石作为基层,形成级配碎石柔性基层和半刚性底基层组成的组合式路面结构,可以解决半刚性路面排水不良、反射裂缝等问题。试验路的实践证明,该组合式结构具有优良的路用性能。

Laying grading macadam as base on semi-rigid type base to form the combined pavement structure using the grading macadam flexible base with the semi-rigid base, it can work out some problems such as drainage badly and reflect pavement crack. The examination in test road shows, it has good road use performance for the combined structure.
