沥青稳定碎石混合料 bituminous stabilization aggregate paving mixtures(英),asphalt-treated permeable base(美) 由矿料和沥青组成具有一定级配要求的混合料,按空隙率、集料最大粒径、添加矿粉数量的多少,分为密集配沥青稳定碎石(ATB)、开级配沥青碎石(OGFC表面层及ATPB基层)、半开级配沥青碎石(AM)。
试验结果表明:同时采用纤维加筋和干拌橡胶粉技术,可以综合二者优势获得具有良好高温稳定性的多碎石沥青混合料;
The results show that it can improve the high temperature stability of stone asphalt concrete by making use of the advantages of the fibers and the rubbers.
在国内外沥青稳定碎石研究的基础上,给出了功能层混合料矿料级配组成的设计和评价方法及功能层混合料配合比设计方法。
Besides, based on the research at home and abroad, we proposed design and evaluation method of asphalt treated base aggregate gradation and mixture design method of asphalt treated mixture.
