经济发展突飞猛进,人民生活日新月异,经济发展对交通运输的运力运量也提出了更高、更大、更多的需求;随着改革开放的不断深入,不仅车辆的数目与日俱增,而且吨位大、运距长是目前交通运输的一大特色。为了适应这种新的运输格局,城市道路建设也得到了极大的发展。道路建设中,沥青路面的应用不仅提高了道路运输行驶的舒适性,噪音低是城市道路的优选路面。随着沥青混合料拌合与摊铺以及碾压机械设备在我国的自主研发,工程施工快捷便利,沥青路面施工方便,维修简单,抗滑性能好,安全系数高,使沥青路面得到了长足的发展与广泛的应用。但是优点与缺点并存,由于沥青材料高温的推移性和低温的开裂性,也给道路行车安全造成了一些不容忽视的隐患,尤其是路面裂缝的产生,给道路安全运营及使用年限带来不可估量的经济损失。本文主要就是通过分析沥青路面裂缝产生的原因和危害,阐述一些相关的防治和处理措施。
With rapid economic development and ever-changing people’s lives, economic development has also put forward higher, bigger and more demands on the transport capacity. With the deepening of reform and opening up, not only has the number of vehicles been increasing day by day, Long distance is a major feature of transportation. In order to adapt to this new transport pattern, urban road construction has also been greatly developed. Road construction, the application of asphalt pavement not only improves the comfort of road transport, low noise road is the preferred road. With the asphalt mixing and paving and roller compaction machinery and equipment in China’s independent research and development, construction quick and easy, asphalt pavement construction convenience, simple maintenance, good skid resistance, high safety factor, the asphalt pavement has been a long Development and wide application. However, the advantages and disadvantages coexist. Due to the high temperature of asphalt and the low temperature cracking resistance, some dangers that can not be neglected are also caused by the road traffic safety. In particular, the cracks in the road surface bring immeasurable benefits to the road safety operation and service life The economic loss. This article is mainly through the analysis of the causes and hazards of asphalt pavement cracks, explain some of the relevant prevention and treatment measures.
