Composite rubber asphalt, mixture of composite rubber asphalt and high-crack-resistance high-rut-resistance three-layer rubber asphalt pavement structure containing mixture
The invention discloses composite rubber asphalt which is prepared from rubber powder, matrix asphalt, graphite and diatomite. The invention also provides a composite rubber asphalt mixture prepared from the composite rubber asphalt and aggregate. In addition, the invention further provides a high-crack-resistance and high-rut-resistance three-layer rubber asphalt pavement structure containing themixture. The pavement structure comprises a tight skeleton embedded and extruded type rubber asphalt concrete upper surface layer, a thick skeleton embedded and extruded type rubber asphalt concretemiddle surface layer and an anti-segregation embedded and extruded skeleton extruded type rubber asphalt lower surface layer which are sequentially laid from top to bottom. According to the pavement structure, the fatigue deformation resistance, crack resistance, rut resistance and other properties of the pavement can be comprehensively improved, a series of problems of pavement reflection cracksand the like caused by fatigue cracking of surface layer aging and cracking of a base layer are solved in a targeted mode, the increasingly-increased environmental and economic pressure of waste tirescan be relieved, and the resource consumption and the construction and maintenance cost of the whole life cycle of the pavement are greatly reduced. Good economic and social benefits are realized.
本发明公开一种复合橡胶沥青，由橡胶粉、基质沥青、石墨和硅藻土制备而成。本发明还提供利用一种由所述复合橡胶沥青和集料制成的复合橡胶沥青混合料。此外，本发明还提供含有该混合料的高抗裂抗车辙三层橡胶沥青路面结构。该路面结构包括自上而下依次铺设的紧密骨架嵌挤型橡胶沥青砼上面层、粗型骨架嵌挤密实型橡胶沥青砼中面层、抗离析嵌挤骨架挤密型橡胶沥青下面层。本发明的路面结构可综合提高路面的抗疲劳变形、抗裂、抗车辙等性能，针对性地解决因面层老化的疲劳开裂，基层开裂引起的路面反射裂缝等一系列问题，还能缓解与日俱增的废旧轮胎的环境和经济压力，大幅降低路面全寿命周期的资源消耗与建养成本。具有良好的经济和社会效益。
