一种传荷式半刚性基层沥青路面结构
摘要：
本发明公开了一种传荷式半刚性基层沥青路面结构，该传荷式半刚性基层沥青路面结构由沥青面层、半刚性基层、刚度过渡层、路基构成，沥青面层设置在半刚性基层上部，半刚性基层设置在刚度过渡层上部，刚度过渡层设置在路基上部，沥青面层由中上面层及下面层构成，中上面层设置在下面层上部；本发明实现了将传统承重式半刚性基层沥青路面结构转变为一种传荷式半刚性基层沥青路面结构，进而提高了半刚性基层、沥青面层的使用寿命。本发明显著提升了沥青路面的耐久性，有效地降低了全寿命周期成本，提高了公路建设的标准和服务水平。
摘要（英）：

The invention discloses a loading transmission type semi-rigid base asphalt pavement structure. The loading transmission type semi-rigid base asphalt pavement structure is composed of an asphalt surface layer, a semi-rigid base, a rigidity transition layer and a roadbed, the asphalt surface layer is arranged on the semi-rigid base, and the semi-rigid base is arranged on the rigidity transition layer; the rigidity transition layer is arranged on the roadbed, the asphalt surface layer is composed of upper, middle and lower surface layer parts, and the upper and middle surface layer parts are arranged on the lower surface layer part; a traditional bearing type semi-rigid base asphalt pavement structure is converted into the loading transmission type semi-rigid base asphalt pavement structure,and the service life of the semi-rigid base and the asphalt surface layer is further prolonged. According to the loading transmission type semi-rigid base asphalt pavement structure, the durability of an asphalt pavement is significantly improved, the whole life cycle cost is effectively reduced, and the standard and service level of road construction are improved.
