沥青橡胶路面材料是目前在国内已经逐渐由试验路面上使用转入到正式商业性生产和使用的一种路面材料,使用这种路面材料能延长路面的使用寿命、减少路面反射裂缝。这种材料是由筑路沥青和可溶于沥青的非耐油橡胶,按一定的制备工艺要求制作而成的。沥青和橡胶相互反应,形成了一种具有回弹性能的、高粘度的热凝胶状混合物。这种混合物在常温以上时,其粘度比沥青的粘度高,在低温时其粘度则比沥青的粘度低。由于它是一种在常温以上呈高粘度的凝胶状混合物,因此在用普通设备进行路面施工时会带来一定的困难。根据国外资料介绍可加入稀释剂,其有:苯、石脑油、四氯化碳、
Asphalt rubber pavement material is currently a kind of pavement material that has been gradually transferred from the test pavement to the formal commercial production and use in China. The pavement material can prolong the service life of the pavement and reduce the reflection cracks on the pavement. This material is made of road asphalt and asphalt-soluble non-oil rubber, made according to certain requirements of the preparation process. The bitumen and the rubber react with each other to form a highly viscous, hot-gelatinous mixture of resilient properties. This mixture at room temperature and above, its viscosity higher than the viscosity of asphalt, its viscosity at a lower temperature than asphalt viscosity. As it is a gel-like mixture that exhibits a high viscosity at room temperature, it can cause some difficulties in pavement construction using ordinary equipment. According to foreign information can be added to the diluent, which are: benzene, naphtha, carbon tetrachloride,
