RA抗车辙沥青混合料的应用技术研究

Analysis on the Application Technology of RA Anti-rut Asphalt Mixture

车辙病害是当前公路普遍存在的问题,RA抗车辙沥青混合料可以有效缓解沥青路面的车辙问题。本文以长大纵坡路段大修工程为依托,从RA抗车辙沥青混合料的施工技术、质量检测、经济性三个角度阐述了其应用情况,表明掺加RA抗车辙剂的沥青混合料具有良好的路用性能,而且应用成本较低,具有良好的推广价值。

Rut disease is a universal problem existed in the road. RA anti-rut asphalt mixture can effectively allevi-ate the problem of asphalt pavement rutting. This paper, relying on the maintenance engineering of longitudinal sec-tions, elaborates its application from three aspects of RA anti-rut asphalt mixture construction technology, quality in-spection, and economic benefit. It shows that RA anti-rut asphalt mixture has good road performance, lower applica-tion cost, and good promotional value.
