Novel asphalt mixture for pavement construction
The invention discloses a novel asphalt mixture for pavement construction. The novel asphalt mixture is prepared from the following raw materials in percentage by weight: 3 to 8 percent of rock asphalt modified asphalt, 4 to 6 percent of mineral, 82 to 90.7 percent of aggregate, 0.3 to 1 percent of a coupling agent and 2 to 3 percent of a filler, the rock asphalt modified asphalt is prepared fromrock asphalt, matrix asphalt, a stabilizer and nano vitrified micro bubbles, the percentage content of the rock asphalt in the rock asphalt modified asphalt is 3-5%, the percentage content of the matrix asphalt in the rock asphalt modified asphalt is 87.2-92.8%, the percentage content of the stabilizer in the rock asphalt modified asphalt is 0.2-0.8%, and the percentage content of the nano vitrified micro bubbles in the rock asphalt modified asphalt is 4-7%. The invention aims to solve the problem that matrix asphalt is modified by utilizing the characteristics of rock asphalt, according to the modified asphalt and the preparation method thereof, the excellent properties of the modified asphalt and the nano glass beads are brought into full play, particularly the properties of the modifiedasphalt are further optimized by adding the nano glass beads, so that the modified asphalt not only has good stability and rut deformation resistance, but also has heat insulation and pavement heat absorption reduction capabilities.
一种用于路面建设的新型沥青混料，包括如下原料及百分含量：岩沥青改性沥青3‑8%、矿料4‑6%、集料82‑90.7%、偶联剂0.3‑1%、填料2‑3%；其中，所述岩沥青改性沥青包括岩沥青、基质沥青、稳定剂、纳米玻化微珠组成，所述岩沥青在岩沥青改性沥青百分含量为3‑5%，所述基质沥青在岩沥青改性沥青百分含量为87.2‑92.8%，所述稳定剂在岩沥青改性沥青百分含量为0.2‑0.8%，所述纳米玻化微珠在岩沥青改性沥青百分含量为4‑7%。本发明的目的是解决利用岩沥青本身的特性改性基质沥青，提供充分发挥它们的优异性能，特别是纳米玻璃微珠的加入，更进一步优化了改性沥青的性能，使改性沥青不仅具有很好的稳定性和抗车辙变形能力，还具有隔热，降低路面吸热能力。
