SBS rubber powder modified asphalt, preparation method and pavement construction method thereof
The invention discloses SBS rubber powder modified asphalt, a preparation method and a pavement construction method thereof. The SBS rubber powder modified asphalt is prepared from, by weight, 75-78 parts of matrix asphalt, 19-21 parts of rubber powder, 1-6 parts of an SBS modifier and 0.1-0.5 part of a stabilizer. The rubber powder adopted by the SBS rubber powder modified asphalt is formed by processing waste tires, the methods of incineration, landfill and the like adopted for the waste tires in part of regions are changed, and a cyclic utilization way is provided for solving the problem ofblack pollution caused by the tires through a reprocessing method. The SBS rubber powder modified asphalt has relatively high high-temperature stability, low-temperature flexibility, aging resistance, fatigue resistance and water damage resistance; the asphalt is used as one of asphalt pavement raw materials, so that the high-temperature stability and the low-temperature crack resistance of the asphalt pavement are greatly improved, the service life of the asphalt pavement is prolonged, and the additional cost generated by later maintenance of the asphalt pavement is reduced. The SBS rubber powder is adopted to modify the asphalt pavement, has a positive effect on noise pollution prevention and control, and can reduce the driving noise by 2-3 decibels.
本申请公开了一种SBS橡胶粉改性沥青、制备方法及其路面施工方法，包括以下重量份的组分，基质沥青：75‑78份，橡胶粉：19‑21份，SBS改性剂：1‑6份，稳定剂：0.1‑0.5份。SBS橡胶粉改性沥青采用的橡胶粉由废旧轮胎加工而成，改变了部分地区对废旧轮胎采取的焚烧、填埋等做法，通过再加工的方法为解决轮胎造成的黑色污染提供了一种循环利用的途径。SBS橡胶粉改性沥青本身具有较高的高温稳定性、低温柔韧性、抗老化性、抗疲劳性、抗水损坏性，采用该种沥青作为沥青路面原材料之一，极大的提升了沥青路面的高温稳定性和低温抗裂性，延长了沥青路面的使用寿命，减少了后期沥青路面维护产生的额外成本。采用SBS橡胶粉改性沥青路面，对于噪声污染防治具有积极作用，可降低行车噪音2‑3分贝。
