Flexible roadbed asphalt concrete structure and construction method thereof
The invention discloses a flexible roadbed asphalt concrete structure which comprises a sub-base layer, a base layer, an anti-fatigue asphalt layer, a tension-compression transition layer, an asphaltmiddle-lower surface layer and an asphalt upper surface layer, the sub-base layer is arranged at the bottommost layer of the roadbed asphalt concrete structure; the base layer is arranged on the upperlayer of the sub-base layer; the anti-fatigue asphalt layer is arranged on the upper layer of the base layer; the tension-compression transition layer is arranged on the upper layer of the anti-fatigue asphalt layer; the asphalt middle-lower surface layer is arranged on the upper layer of the tension-compression transition layer; the asphalt upper surface layer is arranged on the upper layer of the asphalt middle-lower surface layer. According to the invention, a structural scheme of the waterproof anti-rut asphalt upper surface layer, the asphalt middle-lower surface layer, the tension-compression transition layer and the anti-fatigue asphalt layer is determined, three structural form parameters of the structural scheme are designed and demonstrated, and the flexible base asphalt pavement with excellent performance is provided.
一种柔性路基沥青混凝土结构，包括底基层、基层、抗疲劳沥青层、拉压过渡层、沥青中下面层和沥青上面层；底基层，设置于路基沥青混凝土结构的最底层；基层设置于所述底基层的上层；抗疲劳沥青层设置于所述基层的上层；拉压过渡层设置与所述疲劳沥青混合层的上层；沥青中下面层设置于所述拉压过渡层的上层；沥青上面层设置于所述沥青中下面层的上层。本发明确定了防水抗车辙沥青上面层+沥青中下面层+拉压过渡层+抗疲劳沥青层的结构方案，并对结构方案进行了三种结构形式参数的设计论证，提出了具有优异性能的柔性基层沥青路面。
