摘要
为了提高沥青路面的使用寿命,减少病害的产生,辽宁省在高速公路沥青路面结构设计方面尝试了多种改变,但沥青路面破损是受环境、交通、管理、施工等因素的影响,病害产生的机理和原因也各不相同,可能是一种因素或者几种因素共同作用的结果。选取了典型路段,对路面冻胀、裂缝进行跟踪观测,并钻取芯样,初步分析病害产生原因、发展趋势和可利用程度,为进一步提出针对性的沥青路面病害维修方案奠定基础。
In order to improve the service life of asphalt pavement and reduce the occurrence of diseases,Liaoning Province has tried a variety of changes in the structural design of expressway asphalt pavement,but the damage of asphalt pavement is affected by the environment,traffic,management,construction and other factors,and the mechanism and causes of diseases are also different,which may be the result of one or several factors.Therefore,this paper selects the typical road section,tracks and observes the frost heaving and cracks of the pavement,and drills core samples to preliminarily analyze the causes of the disease,development trend and utilization degree,so as to lay the foundation for further proposing the targeted maintenance scheme of asphalt pavement disease.
