Concrete plaited block base layer of asphalt pavement
The invention discloses a concrete plaited block base layer of an asphalt pavement, which comprises plaited block bodies, the side surfaces of the plaited block bodies are inclined surfaces, and the plurality of plaited block bodies establish an embedding and extruding relationship through the inclined surfaces to form a plaited block base layer plane structure with vertical interlocking and plane interlocking. According to the concrete plaited block base layer, concrete precast blocks meeting certain conditions are defined as braided blocks on the basis of the braiding technology, joints between the blocks can be kept in a tightly attached state by means of the overlying relation between the braided blocks, the joint load transfer capacity of the blocks is improved, the vertical interlocking and transverse interlocking relation can be established between adjacent base blocks, the road base layer is gradually diffused to all the woven blocks under the load action through the combined woven grid structure, an annular rewinding and laminating relation is shown around the centers of net openings of the woven blocks, and the road base layer has plate body stability and has practical significance in the aspects of enhancing the stability of the base layer plate body, preventing reflection cracks of a rigid-flexible composite road surface, prolonging the service life of the base layer, reducing life-cycle cost and the like.
本发明公开了一种沥青路面的混凝土编块基层，包括编块体，所述编块体的侧面为斜面，所述多个编块体间通过所述斜面建立嵌挤关系形成竖向互锁及平面连锁的编块基层平面结构。本发明基于编织技术定义符合一定条件的混凝土预制块体为编块，依靠编块之间叠压关系可保持块体间接缝处受压紧处于密贴合状态，提高块体的接缝传荷能力，又能在相邻基块之间建立竖向互锁及横向联锁关系，合纵连横的编织网格结构使道路基层在荷载作用下逐级扩散到所有编块，围绕编块网口中心呈现环形回绕叠压关系，具有板体稳定性，对增强基层板体稳定性、预防刚柔复合式路面的反射裂缝、提高基层使用寿命，降低全寿命费用等方面具有实际意义。
