半刚性基层沥青路面层间结合室内试验研究

The indoor test research on the interlayers combining of semi rigid base asphalt pavement

沥青路面基面层间结合状态的好坏,主要体现在层间抗剪切变形的能力以及层间的粘结性能。抗剪切变形能力强、粘结性能好,则层间不容易出现滑动,反之,层间容易出现滑动,导致层间及沥青层内应力水平提高,进而影响沥青路面的使用性能,对基面层间结合状态进行室内试验研究,能有效地指导路面结构的设计与施工,从而提高半刚性沥青路面结构的使用寿命。

Asphalt pavement interfacial combining state is mainly embodied in the interlayer shear deformation capability and the interlayer bonding properties. Shear deformation ability, good bonding properties between layers, which is not prone to sliding, conversely, layer is easy to slip, causing interlayer and asphalt layer stress level, then influence the performance of asphalt pavement, on the surface of the base contact condition between layers were studied by indoor experiments, can effectively guide the design of pavement structure and construction, thereby improving the semi - rigid asphalt pavement service life.
