Semi-flexible asphalt pavement surface layer structure
The invention discloses a semi-flexible asphalt pavement surface layer structure which is a composite asphalt pavement structure formed by pouring a high-flow-state, super-early-strength and low-shrinkage composite grouting material into high-performance large-gap asphalt concrete. The high-performance large-gap asphalt concrete adopts high-communication gap and aggregate secondary interlocking type skeleton gap type grading, and the composite grouting material is formed by mixing water, Portland cement, emulsified asphalt, regenerated glass particles, regenerated tourmaline powder, regenerated rubber particles and a composite additive according to a certain proportion. The structural strength of the composite asphalt pavement structure can be improved, the pavement temperature is reduced (the urban heat island effect is relieved), nitric oxide discharged by automobile exhaust is absorbed, meanwhile, the composite asphalt pavement structure has remarkable high bearing capacity and super-strong anti-shearing and anti-rutting performance, and can be applied to any road and urban road, and the service life of the composite asphalt pavement structure is prolonged. The method is particularly applied to low-speed, heavy-load and high-pollution area road sections such as road truck heavy-load lanes, long and large climbing lanes, urban bus special lanes, intersections and parking lots.
本发明公开了一种半柔性沥青路面面层结构，由高性能大空隙沥青混凝土中灌入高流态、超早强、低收缩的复合灌浆材料形成的复合沥青路面结构。高性能大空隙沥青混凝土采用高连通空隙、集料二级嵌锁形式的骨架空隙型级配，复合灌浆材料由水、硅酸盐水泥、乳化沥青、再生玻璃颗粒、再生电气石粉、再生橡胶颗粒及复合外加剂按照一定比例混合而成。本发明可提高复合沥青路面结构的结构强度、降低路面温度(缓解城市热岛效应)、吸收汽车尾气排放的氮氧化物，同时具有显著的高承载力、超强的抗剪切和抗车辙性能，可应用于任何公路及城市道路，特别应用于公路货车重载车道、长大爬坡、城市公交专用车道、交叉口、停车场等低速、重荷载、高污染区域路段。
