Anti-crack pavement structure and construction method
The invention provides an anti-crack pavement structure and a construction method, and relates to the technical field of municipal engineering. The anti-crack pavement structure comprises a pavement structure located on a roadbed. The pavement structure sequentially comprises a graded broken stone hardcore, an inorganic binder stabilizing material base layer, a graded broken stone base layer and an asphalt concrete surface layer from bottom to top. The graded broken stone of the anti-crack pavement structure provided by the invention belongs to granular mixtures, and the problem of reflection cracks of the asphalt concrete surface layer is solved by virtue of the dissipation effect of the graded broken stone on stress, that is, when the inorganic binder stabilizing material base layer generates cracks, the graded broken stone base layers are arranged on the inorganic binder stabilizing material base layer and the asphalt concrete surface layer, and the graded broken stone base layer can dissipate stress, so that the problem of emission cracks of the inorganic binder stabilizing material base layer is solved.
本发明提供了一种抗裂路面结构及施工方法，涉及市政工程的技术领域，该抗裂路面结构包括位于路基上的路面结构，所述路面结构包括由下而上依次为级配碎石垫层、无机结合料稳定材料基层、级配碎石基层和沥青混凝土面层。本发明提供的抗裂路面结构的级配碎石属于散粒体，借助其对应力的消散作用解决沥青混凝土面层反射裂缝的问题，即在无机结合料稳定材料基层产生裂缝的时候，由于在无机结合料稳定材料基层和沥青混凝土面层有级配碎石基层，级配碎石基层能够消散应力，进而解决无机结合料稳定材料基层发射裂缝的问题。
