高速路面中面层应用Superpave技术要点

Surface layer applying Superpave technology points on highway pavement

对AC混合料与Superpave混合料进行了对比,从沥青分级、集料技术指标及设计方法方面分析了两者的不同,介绍了Superpave混合料的配合比设计要点和原材料、拌和、摊铺及碾压等工序中的质量控制要点,指出Superpave路面是解决我国路面早期损坏问题,特别是车辙病害的有效途径。

The paper compares AC mixture to Superpave mixture,analyzes their differences from aspects of asphalt grading,aggregate technology indicators and design methods,introduces the quality control points of Superpave mixture at various phases including mixing proportion design,raw material,mixing,paving and rolling and other procedures,and finally points out that： Superpave pavement is an effective way to solve domestic pavement early damage problems especially the rutting diseases.
