Anti-indentation asphalt pavement and modified asphalt
The invention relates to an anti-indentation asphalt pavement and modified asphalt. The anti-indentation asphalt pavement comprises a first pavement layer, a second pavement layer and a third pavement layer, the first pavement layer is laid on a pavement base layer, part of the first pavement layer permeates into the pavement base layer and is stacked on the surface of the pavement base layer by 8-12 mm, part of the second pavement layer permeates into the first pavement layer and is stacked on the surface of the first pavement layer by 7-10 mm, and part of the third pavement layer permeates into the second pavement layer and is stacked on the surface of the second pavement layer by 15-20 mm; raw materials adopted by the first pavement layer comprise first modified asphalt, macadam, steel slag and the like; raw materials adopted by the second pavement layer comprise second modified asphalt, modified basalt fibers and the like; and raw materials of the third pavement layer comprise third modified asphalt, talcum powder and the like. The asphalt pavement provided by the invention is high in anti-indentation performance and high temperature resistance and freezing resistance, the service life of the asphalt pavement can be prolonged, the maintenance and repair cost is reduced, and the transportation efficiency and driving safety of road traffic are improved.
本发明涉及一种防压痕沥青路面及改性沥青，防压痕沥青路面包括第一路面层、第二路面层和第三路面层；第一路面层铺设在路面基层上，第一路面层部分渗入路面基层中并在路面基层表面堆叠8‑12mm厚度，第二路面层部分渗入第一路面层中并在第一路面层表面堆叠7‑10mm厚度，第三路面层部分渗入第二路面层中并在第二路面层表面堆叠15‑20mm厚度；第一路面层采用的原料包括第一改性沥青、碎石和钢渣等；第二路面层采用的原料包括第二改性沥青和改性玄武岩纤维等；第三路面层的原料包括第三改性沥青和滑石粉等。本发明提供的沥青路面防压痕性能、抗高温和抗冷冻性能好，能延长沥青路面的使用寿命，降低养护和维修成本，提高道路交通的运输效率和行车安全。
