摘要
通过在路用基质沥青中掺入布敦岩天然沥青,研究改性后沥青的性能和干湿两种工艺下沥青混合料的路用性能对比,发现无论是沥青材料本身还是改性后沥青混合料其高温稳定性都有显著的改善,同时试验结果表明干法工艺的改性沥青混合料的高温抗车辙能力和抗水损害性能明显优于湿法的改性沥青混合料。
Through adding BMA into petroleum asphalts,this paper studies the road performance of modified asphalts and mixture in dry-wet way.Improvements are observed in high-temperature durability whether asphalts material or asphalt mixture.Test result indicate that dry way of modified asphalt mixture in high-temperature durability and anti-water damage is better than wet way.
