摘要
介绍了天然岩沥青的路用性能,分析了天然岩沥青改性沥青混合料的性能,结合工程概况,针对该项目路段上出现的严重车辙病害,提出了采用岩沥青改性沥青处理的方案,实践表明,普通基质沥青经过天然岩沥青改性后,可很好地改善路面使用性能,具有推广应用价值。
It introduces road functions of natural rock bitumen, analyzes the functions of natural rock bitumen mixtures, Combined with the general conditions of project, according to heavy rut diseases of this item section, it brings forward plans of processing rock bitumen. The practice shows, after changing into natural rock bitumen, common basic bitumen can improve the using functions of mad surface greatly, which worth spreading.
