为了提高改、扩建工程沥青路面的路用性能,选取双绞合钢丝网、自粘式玻纤格栅、钢塑复合土工格栅及聚酯长丝土工布等4种加筋材料,并分别设置于基面层间和面层层间。通过大量室内加筋组合试件的性能试验,分析比较了不同加筋组合试件的路用性能和抗差异沉降能力。研究结果表明:独特三维网孔结构的双绞合钢丝网具有优良的物理力学性能,耐腐蚀,强度高,抗疲劳,整体性好,抗变形能力强。与未加筋的相比,不同筋材加筋有效地提高了沥青路面的抗高温车辙和抗低温开裂性能,以及抗差异沉降开裂能力。当筋材铺筑于面层层间时,有利于提高沥青路面的抗车辙能力;当筋材铺筑于基面层间时,有利于提高沥青路面的抗裂...

In order to improve the pavement performances of asphalt pavements in reconstruction and extension engineering, four kinds of reinforced materials, including double twisted steel wire mesh, self-adhered glass fiber grill, steel-plastic composite geogrid and polyester-filament geotextile, were selected to install the interlayer between base and surface as well as surface layers, respectively. Lots of labor performance experiments for reinforced composite specimens were conducted to analyze and compare the pavement performances and the capacities of differential settlement resistance of differen...
