Composite pavement structure based on steel slag asphalt mixture
The invention discloses a composite pavement structure based on a steel slag asphalt mixture, which comprises an asphalt structure base layer, the bottom of the asphalt structure base layer is paved with a binding layer, the bottom of the binding layer is provided with a waste rubber cushion layer, the bottom of the waste rubber cushion layer is provided with a waste plastic layer, and the waste plastic layer covers the base layer structure. The surface of the subbase layer is covered with a cobblestone laying layer, a cement leveling layer is laid on the upper side of the cobblestone laying layer, a base layer structure is arranged on the surface of the cement leveling layer, a quartz sand and blue stone cushion layer is arranged at the bottom of the subbase layer, and the quartz sand and blue stone cushion layer is laid on a soil base. According to the composite pavement structure based on the steel slag asphalt mixture, solvent oil and liquid paraffin serve as plasticizers; crisp in a cold environment belongs to stress cracking, the solvent oil and the liquid paraffin can increase the softness among asphalt molecules, and the asphalt has the advantages of being low in cost and improving the crack resistance of a pavement.
本发明公开了一种基于钢渣沥青混合料的复合路面结构，包括：沥青结构基层，所述沥青结构基层的底部铺设有联结层，且联结层的底部设置有废旧橡胶垫层，同时废旧橡胶垫层的底部设置有废旧塑料层，并且废旧塑料层覆盖在基层结构上，底基层的表面覆盖有鹅卵石铺设层，且鹅卵石铺设层的上侧铺设有水泥找平层，并且水泥找平层的表面设置有基层结构，底基层的底部设置有石英砂与青石子垫层，且石英砂与青石子垫层铺设在土基上。该基于钢渣沥青混合料的复合路面结构，溶剂油和液体石蜡作为增塑剂；寒冷环境中的酥脆属于应力开裂,溶剂油和液体石蜡可增加沥青分子之间的柔软度，具有成本低，提高路面抗裂能力的优点。
