Asphalt highway mixture and construction method thereof
The invention discloses an asphalt highway mixture which comprises the components by weight: 60-100 parts of waste asphalt, 20-30 parts of waste tires, 30-50 parts of tailings, 10-25 parts of diatomite, 5-15 parts of heavy calcium carbonate powder, 10-20 parts of clay, 5-15 parts of shells, 10-15 parts of a viscous component, 20-40 parts of a fiber component, 5-10 parts of resin, 40-60 parts of building waste and 100-200 parts of water. A construction method comprises the steps: paving the asphalt mixture by selecting pavers, and rolling the paved asphalt mixture by following a steel wheel road roller and a rubber wheel road roller behind each paver. The asphalt road mixture provided by the invention has excellent cracking resistance, water retention capacity and pressure resistance, a large amount of waste materials are adopted, the production cost is reduced, and the provided construction method can improve the paving quality of the asphalt mixture.
本发明公开了一种沥青公路混合料，包括按照重量计的废旧沥青60～100份、废旧轮胎20～30份、尾矿石30～50份、硅藻土10～25份、重钙粉5～15份、粘土10～20份、贝壳5～15份、粘性组分10～15份、纤维组分20～40份、树脂5～10份、建筑废料40～60份和水100～200份；施工方法为选用摊铺机对所述沥青混合料进行摊铺，每台摊铺机后紧跟钢轮压路机和胶轮压路机，碾压摊铺后的沥青混合料。本发明提供的一种沥青公路混合料具有出色的抗开裂能力、保水性能、抗压能力，且大量采用废旧材料，降低了生产成本，提供的施工方法能够提高沥青混合料的铺设质量。
