沥青路面常见病害及其预防措施论文

浅谈沥青路面常见的病害及其预防措施摘要随着我国道路建设的迅速发展，沥青路面的施工得到了普遍推广应用。沥青路面具有表面平整，坚实、无接缝、施工工期短和养护简便等优点，使行车噪声低、平稳和舒适。但随着交通量的增长和重载超载车辆的增多，加上由于受到温度和湿度的变化以及冰冻作用、设计、施工、采用材料和养护管理等因素的影响，出现了多种沥青路面病害，如结构性破坏裂缝、沥青路面的裂缝、松散及水损害等等。根据长期对我区沥青路面的实际情况调查，谈谈沥青路面中常见的病害与裂缝出现的原因及其预防措施。[ 关键词 ] 公沥青路面；病害；裂缝；Abstract Along with the rapid development of our country road construction, of the asphalt pavement construction to be universal application. The asphalt pavement is smooth, solid, no juncture, short construction period and maintenance convenient wait for an advantage, make traffic noise is low, smooth and comfortable. But as the volume of traffic of the growth and heavy-load overload the increase in vehicles, plus due to temperature and humidity changes and dehydrating action, design, construction, using materials and maintenance management of the factors such as asphalt pavement appeared a variety of diseases, such as structural damage cracks, asphalt pavement.this crack, loose and water damage, etc. According to the long-term attractors among asphalt pavement.this actual situation investigation, talk about the asphalt pavement of common diseases and cracking causes and prevention measures.
