摘要
近年来,受行车荷载和自然因素等的长期作用,沥青路面在使用过程中极易产生老化、裂缝等早期病害问题。此类病害的产生将对道路行驶舒适性及安全造成严重影响,甚至缩短路面使用寿命。就地热再生技术作为一种高效、低耗、低成本的预防性养护技术,在我国沥青路面养护维修中得到了广泛应用。为此,本文结合具体工程案例,对旧沥青路面主要病害及成因进行了分析,并确定了施工方案,最后阐述了就地热再生技术在沥青路面中修施工中的应用。
In recent years,due to the long-term effects of traffic load and natural factors,asphalt pavement is prone to produce early diseases such as aging,cracks and so on.The occurrence of such diseases will have a serious impact on road driving comfort and safety,and even shorten the road service life.As a high efficiency,low consumption and low cost preventive maintenance technology,hot in-place recycling technology has been widely used in asphalt pave⁃ment maintenance and repair in China.Therefore,combined with specific engineering cases,this paper analyzed the main diseases and causes of the old asphalt pavement,determined the construction scheme,and finally expounded the application of hot in-place recycling technology in the construction of asphalt pavement intermediate repair.
