热拌沥青混合料(以下简称沥青混合料)作为性能优良的道路建筑材料,已被广泛用于城市道路和高等级公路建设,但由于沥青路面长期直接承受行车荷载和自然因素作用,如何保证路面质量,提高路面的使用耐久性,减少路面早期损坏等问题一直是广大公路建设者不断探讨的课题。沥青路面产生病害的原因比较复杂,各地因为环境、地理及气候条件不同,出现病害的方式或程度也各不相同,山西省运城市属于夏炎热冬寒类(即122区)气候,气候条件较为炎热,有些公路通车不久就出现了早期损坏现象,比较常见的病害如泛油、车辙、松散及坑槽等,笔者试从以下几个方面对沥青路面产生早期病害的原因进行分析。
Hot asphalt mixture (hereinafter referred to as asphalt mixture) as a high performance road building materials, has been widely used in urban roads and high-grade highway construction, but asphalt pavement long-term direct bearing load and natural factors, how to ensure the pavement The problems of quality, improving the durability of the pavement and reducing the early damage to the pavement have always been the topics that the highway builders are constantly discussing. Asphalt road disease causes more complicated, because of different environmental, geographical and climatic conditions, the way or degree of disease are also different, Shanxi Yuncheng belongs to the summer hot and cold winter (ie 122) climate, climate conditions are Hot, some roads opened to traffic soon appeared early damage phenomenon, the more common diseases such as oil pan, rutting, loose and pit, the author try from the following aspects of asphalt pavement causes early disease analysis.
