长大纵坡路段沥青路面车辙防治研究

Study on Rut Prevention and Control of Asphalt Pavement in Long Longitudinal Slope

长大纵坡路段沥青路面车辙病害会严重影响到路面的正常使用,为探究其防治措施,本文通过工程实践,考虑到PR抗车辙剂可有效提高沥青路面抗车辙能力,对PR抗车辙剂在某高速公路长大纵坡路段的应用进行了研究,在某高速公路K945+180~K946+400长大纵坡路段铺筑不同结构试验路,经过1年的观察与检测发现:该试验路的车辙病害极大减少,可见PR抗车辙剂可有效改善沥青路面长大纵坡路段的车辙破坏现象;试验路车辙病害防治方案可行。

Grow up grade road asphalt pavement rutting disease can seriously affect the normal operation of the road, to explore the prevention and control measures, based on the engineering practice, considering the PR anti-rutting agent can effectively improve the rutting resistance of asphalt pavement, the PR anti-rutting agent in grew up and the application of the longitudinal slope of an expressway were studied, in a certain expressway K945 ＋ 180 - K946 ＋ 400 grew up longitudinal slope road paving test road, different structure after 1 year of observation and inspection found that the test road rut disease significantly reduce, visible PR anti-rutting agent can effectively improve grew up and longitudinal slope section of asphalt pavement rutting damage phenomenon; The prevention and control scheme of rut disease is feasible.
