The invention discloses an asphalt pavement structure with an asphalt layer reflection crack prevention base layer and a construction method, the pavement structure sequentially comprises an asphalt concrete surface layer, the asphalt layer reflection crack prevention base layer and a cement-stabilized subbase layer from top to bottom, the asphalt layer reflection crack prevention base layer comprises large-particle-size framework aggregate and a filler, the filler is a mixture of cement, water and stone, and the cement-stabilized subbase layer is a mixture of cement, water and stone. The large-particle-size framework aggregate forming material is of a large-particle-size framework structure, and the filler is evenly distributed in gaps of the large-particle-size framework structure. By means of the design method, cracks which are reflected upwards from the base layer can be effectively prevented from occurring on the asphalt surface layer of each grade of asphalt road, meanwhile, compared with a full-thickness asphalt pavement, the pavement has the advantage of being low in cost, and compared with an ordinary cement stabilized macadam base asphalt pavement, the pavement has the advantage of being long in service life; the base material can meet the urgent demand of a high-performance asphalt road base material, and provides an asphalt pavement structure based on the asphalt layer reflection crack prevention base material.
防沥青层反射裂缝基层沥青路面结构及施工方法，路面结构从上到下依次包包括沥青混凝土面层、防沥青层反射裂缝基层和水泥稳定底基层，防沥青层反射裂缝基层包括大粒径骨架集料和填充料，填充料是水泥以及水和石料的混合物，大粒径骨架集料形成材料为大粒径骨架结构，填充料均匀分布于大粒径骨架结构的空隙中。本发明通过该设计方法，可以有效防止各等级沥青公路沥青面层出现自基层向上反射的裂缝，同时相较于全厚式沥青路面具备低成本的优势，相较于普通水泥稳定碎石基层沥青路面具备长寿命的优势，能够满足高性能沥青道路基层材料的迫切需求，并提供以该防沥青层反射裂缝基层材料为基础的沥青路面结构。
