The maintenance of highways is very important. It can not only prolong the service life of the roads, but also ensure the safety and smoothness, and it can also reduce the occurrence of traffic accidents. Xiao Bian analyzes the common disease problems in the maintenance of asphalt roads in order to better carry out road maintenance and prevention measures. Asphalt pavement is a relatively common pavement structure, with a smooth surface, solid, seamless, comfortable ride, wear, low noise, short construction period, easy maintenance and maintenance, can absorb water, but also more suitable for construction in phases, etc. Applications. However, due to the differences in the material quality of asphalt concrete and the impact of design and construction, there are eight kinds of common diseases such as cracks, ruts, looseness, frost heaving, sinking, convection, flooding, and cracking. . The occurrence of these diseases has seriously affected the driving speed and driving safety, increased car wear and shortened the service life of asphalt pavements. There are many factors in the occurrence of asphalt pavement diseases, there are design reasons, there are construction reasons. For maintenance Xiao Bian made the following summary: One is to thin the thickness of the asphalt surface layer as appropriate. Mainly for the following four aspects. 1. The carrying capacity of the semi-rigid base asphalt pavement structure can be borne by the semi-rigid material layer (base layer and subbase layer), and no thicker surface layer is needed to improve the carrying capacity. 2. To improve the performance of asphalt pavement, instead of using a thick layer of asphalt, high-quality asphalt is used. 3. Cracks in the asphalt surface layer are not just reflection cracks. Under normal construction conditions, most of them are shrinkage cracks of the asphalt surface itself. 4. In general, a thick asphalt surface layer can easily cause rutting. At the same time, it is also necessary to strengthen the waterproof design of asphalt pavement, and choose a reasonable base layer and subbase structure. The second is to strictly control the quality of the asphalt mixture. The third is to strictly control the construction quality. In short, the maintenance of highway asphalt pavement is very important and very necessary. It is hoped that all relevant units can give them a high enough understanding and concretely do a good job in the maintenance and repair of highways in order to ensure safety, ensure smooth flow, promote development, and promote harmony.
