Green, economical and durable high-grade road asphalt pavement structure
The invention discloses a green, economical and durable high-grade road asphalt pavement structure. The structure comprises a cushion layer, a base layer, a modified asphalt macadam sealing layer, a high-elastic anti-cracking modified asphalt concrete layer, a first modified emulsified asphalt bonding layer, a rubber and plastic composite high-modulus asphalt concrete layer, a second modified emulsified asphalt bonding layer and a high-viscosity modified asphalt mastic macadam SMA concrete layer. And the high-viscosity modified mastic asphalt gravel SMA concrete layer is selected as the upper surface layer, so that the anti-rutting, anti-abrasion and anti-fatigue performances are excellent. The rubber and plastic composite high-modulus asphalt concrete layer is selected as the middle surface layer, and has outstanding rutting resistance and good low-temperature crack resistance; the high-elasticity anti-cracking modified asphalt concrete layer is selected as the lower surface layer, the outstanding anti-fatigue and anti-cracking capacity is achieved, the comprehensive performance is excellent, the total thickness is reduced by 4-6 cm compared with an existing conventional expressway asphalt surface layer structure, and the outstanding economic benefits and social and environmental benefits are achieved.
本发明公开了一种绿色经济耐久的高等级道路沥青路面结构，其包括垫层、基层、改性沥青碎石封层、高弹抗裂改性沥青混凝土层、第一改性乳化沥青粘层、橡塑复合高模量沥青混凝土层、第二改性乳化沥青粘层和高粘改性沥青玛蹄脂碎石SMA混凝土层。选用高粘改性沥青玛蹄脂碎石SMA混凝土层作为上面层，具有优良的抗车辙、抗磨耗、抗疲劳性能。选用橡塑复合高模量沥青混凝土层作为中面层，具有突出的抗车辙性能和良好的低温抗裂性能；选用高弹抗裂改性沥青混凝土层作为下面层，具有突出的抗疲劳、抗开裂能力，本发明综合性能优越,且总厚度与现有常规高速公路沥青面层结构相比减薄4～6cm，具有突出的经济效益和社会环境效益。
