Anti-rutting pavement structure and construction method thereof
The invention discloses an anti-rut pavement structure and a construction method thereof, and relates to the field of road engineering construction. The anti-rut pavement structure comprises a semi-rigid base layer, an anti-rut performance layer and a modified asphalt pavement layer which are sequentially arranged from bottom to top; the anti-rutting performance layer is composed of a large-gap asphalt mixture, a latex modifier, cement, standard sand and water; the latex modifying agent is prepared from polyurethane resin, disodium lauryl polyoxyethylene ether sulfosuccinate, nano SiO2 modified polyacrylic resin and acrylamide; the modified asphalt pavement layer is composed of waste rubber powder asphalt, aromatic polycarbonate resin and polyvinyl chloride. According to the invention, construction difficulty and complexity are reduced, the anti-rut pavement structure has good high-temperature stability, low-temperature crack resistance and fatigue resistance, the anti-rut performance of the anti-rut pavement structure is improved, and the construction cost is reduced.
抗车辙路面结构及其施工方法，涉及道路工程建设领域，本发明包括由下至上依次设置的半刚性基层、抗车辙性能层和改性沥青路面层；抗车辙性能层由大空隙沥青混合料、胶乳改性剂、水泥、标准砂和水组成；胶乳改性剂由聚氨基甲酸乙酯树脂、月桂醇聚氧乙烯醚磺基琥珀酸酯二钠、纳米SiO2改性聚丙烯酸树脂和丙烯酰胺组成；改性沥青路面层由废胶粉沥青、芳香族聚碳酸酯树脂和聚氯乙烯组成。本发明在降低了施工难度和复杂度的同时，能够使抗车辙路面结构具有较好的高温稳定性、低温抗裂性和耐疲劳性，提高了其抗车辙性能，降低了施工成本。
