利用废轮胎粉与再生PE产品对沥青进行复合改性,不但环境效益显著,而且其路用性能优良。研究者对胶粉及胶粉复合改性沥青进行了大量的试验与研究,尤其是研究成功的胶粉双复合(Domix)改性沥青,将巴赛尔工程技术(北京)有限公司的Domix用干法与胶粉改性(湿化)沥青进行复合改性,不但发挥了胶粉改性沥青抗老化、抗疲劳、抗低温开裂等路用性能的优势,而且其高温抗车辙性能在南方温炎热区渠化交通、重载交通的高速公路也得到了发挥。其应用前景是广阔的。
The use of waste tire powder and recycled PE product compound modification of asphalt, not only significant environmental benefits, but also its road performance. Researchers have done a great deal of experimentation and research on rubber powder and rubber powder composite modified bitumen. In particular, we have studied the successful Domix modified asphalt produced by Basess Engineering (Beijing) Co., Ltd., Dry method and rubber powder modified (wet) asphalt composite modification, not only play a rubber powder modified asphalt aging resistance, fatigue resistance, low temperature cracking and other road performance advantages, and its high temperature resistance to rutting performance in the southern temperature The hot zone canalization traffic, heavy traffic highway has also been played. Its application prospect is broad.
