本文调查了坑洼问题的严重性，进行了严格的评估，目前的维修做法，并确定资源可用于坑洼维修的基础上，在加拿大的六个省级交通机构的问卷调查结果。调查结果表明，在研究区域中，中度至高度严重的坑洞比例更大。冻融循环被确定为壶穴形成的最有影响力的因素。很大一部分坑洞维修作业是在夏季进行的。经常使用的修补材料是传统的冷拌，热拌沥青，优质路面维修，创新沥青维修。投掷和去的方法是常用的坑洞维修业务在所有季节。冬季修补补丁的耐久性明显低于夏季。裂缝、边缘解体和开裂是修补失败最令人关注的困扰，这可能是修补材料的稳定性、粘附力、内聚力和剥离潜力不足的结果。(c)2018年美国土木工程师协会。
This paper investigates the severity of pothole problems, conducts a critical assessment of current maintenance practices, and identifies resources available for pothole repair based on the results from a questionnaire survey of six provincial transportation agencies in Canada. The survey outcomes indicated a greater percentage of moderate to highly severe potholes in the study area. Freeze-thaw cycles were identified as the most influential factor in pothole formation. A large portion of pothole repair operations are conducted in the summer period. The frequently used patching materials were conventional cold mix, hot-mixed asphalt, Quality Pavement Repair, and Innovative Asphalt Repair. The throw-and-go method is commonly used for pothole repair operations in all seasons. The durability of a winter-repaired patch is significantly less than that of summer. Raveling, edge disintegration, and cracking are the most concerning distresses of patch failure, which could be a result of inadequate stability, adhesion, cohesion, and stripping potential of patching materials.
