Permeable asphalt concrete and preparation method thereof
The invention provides permeable asphalt concrete and a preparation method thereof.The permeable asphalt concrete is prepared from modified asphalt, cement, coarse aggregate, fine aggregate, mineral powder, a water reducing agent and water, and the modified asphalt is formed by mixing asphalt, modified petroleum resin and an antioxidant under the high-temperature shearing effect; the modified petroleum resin is prepared by carrying out copolymerization modification on petroleum resin, an unsaturated monomer and vinyl MQ silicon resin. A base material of the water-permeable asphalt concrete is modified asphalt, the modified asphalt is formed by mixing asphalt, modified petroleum resin and an antioxidant under the high-temperature shearing action, the modified petroleum resin is obtained by taking petroleum resin, unsaturated monomers and vinyl MQ silicon resin as raw materials and carrying out solution polymerization through a free radical initiator, and the modified petroleum resin is obtained by taking the unsaturated monomers and the vinyl MQ silicon resin as raw materials. The modified petroleum resin contains polar groups and has a certain cross-linked structure, so that the softening point and the deformation resistance of the asphalt concrete can be improved. In addition, the water-permeable asphalt concrete disclosed by the invention also has good high-temperature deformation resistance.
本发明提供了一种透水沥青混凝土及其制备方法，沥青混凝土包括如下原料：改性沥青、水泥、粗骨料、细骨料、矿粉、减水剂、水，所述改性沥青由沥青与改性石油树脂、抗氧剂在高温剪切作用下混合而成，所述改性石油树脂是石油树脂经与不饱和单体、乙烯基MQ硅树脂共聚改性制得。本发明透水沥青混凝土的基材为改性后的沥青，改性沥青由沥青与改性石油树脂、抗氧剂在高温剪切作用下混合而成，其中的改性石油树脂是以石油树脂、不饱和单体、乙烯基MQ硅树脂为原料经自由基引发剂，发生溶液聚合得到，改性石油树脂包含极性基团并具有一定的交联结构，可提高沥青混凝土的软化点和抗形变能力。此外，本发明透水沥青混凝土还获得了良好的高温抗形变性能。
