我国自六十年代以来在公路上修建了大量的沥青(渣油)路面,其中以渣油表面处治路面为多数,这些路面的使用年限大部分都已超过六年,有的已达十年以上。由于不少路段已超过了设计使用年限,因此,路面病害日趋严重,道路的改道或大修任务越来越多,由此而产生的沥青(渣油)路面的废料也就大量增加。如何在技术上合理地、有效地将这些旧有路面材料再生,并加以利用,是公路建设中的一个重要研究课题。为此,在我校道路与交通工程
Since the 1960s, China has built a large amount of asphalt (residual oil) pavement on the road, of which the surface treated by residual oil is the majority, most of the useful life of these pavement has been more than six years, and some have reached over ten years . Since many road sections have already exceeded the design service life, the road surface disease is becoming more and more serious. There are more and more diversions or overhauls of the roads, resulting in a significant increase in the waste of asphalt (residual oil) pavement. How to regenerate and utilize these old pavement materials technically and effectively is an important research topic in highway construction. To this end, in my school road and traffic engineering
