摘　　要：阐述目前沥青混凝土添加剂的发展趋势,针对路宝牌高模量外加剂,选取几种常用的改性沥青及混合料添加剂,通过对室内试验以及试验路观测情况进行评价和对比,添加路宝外掺剂的沥青混合料在高温抗车辙方面具有显著的优势,施工工艺简单易行,具有良好的推广和应用前景。The paper elucidates the trend of the additive for asphalt concrete at present. By the test in lab and the observation of experiment road, the paer selects the Lubao brand additive from several kinds of common additives for asphalt concrete. The asphalt mixture which the Lubao brand additive is admixed into has a marked superiority over rut -resistance at high temp. Its construction technology is simple and easy to be operated, owns a good spreading and applied prospects.
