53.沥青混凝土路面病害产生原因防治措施.docVIP

摘 要 沥青路面因具有地质条件适应性强、表面平整、坚实、无接缝、行车舒适、耐磨、噪声低、施工期短、养护维修简便且适于分期修建等优点，在公路与城市道路修建中已广泛应用。在公路通车后，因行车荷载作用、外界环境影响以及设计、施工中存在的不足，沥青路面会逐渐出现多种路面病害，主要有裂缝（纵向裂缝、横向裂缝、龟裂）、变形（车辙、波浪或搓板、沉陷、隆起）、松散（磨光、松散、剥落、坑槽）及其他（泛油）四大类。高速公路一出现路面病害，就应及时分析病害成因，及时采取有效措施进行处治，否则不仅会降低道路的使用性能、影响行车安全、舒适、快捷、通畅，而且会因处理不及时或措施不当导致道路结构性破坏。我根据近几年的学习和实践，分析了公路沥青路面各种病害的形成原因，提出了路面病害的处治方法，并对今后公路建设、设计、施工、管养等方面提出一些建议。 关键词：病害 原因 预防 处治 Abstract Asphalt pavement with the geological conditions for adaptability, smooth surface, solid, seamless, driving comfort, abrasion resistance, low noise, construction period is short, easy maintenance and repairs for construction staging, etc., in highway and urban road construction has been widely used. After the opening of the road, due to traffic loads, external influences, and design and construction deficiencies, asphalt pavement will be the gradual emergence of a variety of diseases, there are cracks (longitudinal cracks, transverse cracks, cracking) and deformation (rutting, wave or a washboard, subsidence, uplift), loose (polished, loose, flaking, pits) and others (Fan) four categories. Highway Pavement Distress appeared, it should be timely analysis of the causes of disease, to take effective measures to Treatment, or the use of roads will not only reduce the performance impact of traffic safety, comfortable, fast, smooth, and due to improper handling or measures do not lead to timely structural damage to the road. In accordance with the study and practice in recent years, analysis of the asphalt pavement causes a variety of diseases, diseases of the road proposed treatment method, and the future road construction, design, construction, custody and other aspects to make some suggestions.
