摘要
随着使用年限与交通量的增加,沥青路面会出现开裂、凹槽、车辙、泛油等多种病害,会极大降低沥青路面的耐久性。通过分析公路沥青路面常见的病害及其成因,并结合工程应用实例,介绍了公路沥青路面出现不同的开裂状况和翻浆后对应的处理措施。经过长期监测与评定发现,处理后的路面能达到设计要求,在一年多的使用过程中未发生路面裂缝、不均匀沉降等病害,表明该技术具有较高的可行性。
With the increase of service life and traffic volume,various diseases such as cracks,grooves,ruts,and oil flooding will occur on the asphalt pavement,which will greatly reduce the durability of the asphalt pavement. The different cracking and frost boiling conditions of highway asphalt pavement and corresponding treatment measures are introduced by analyzing the common diseases and causes of highway asphalt pavement and combined with an engineering application example. It is found that the treated pavement can meet the design requirements and no cracks,differential settlement and other diseases have occurred during more than one year of use after long-term monitoring and assessment,which indicating that the technology has high feasibility.
