为适应经济发展的需要,我市自1983年以来,先后在国、省干线上建成一、二级公路228公里,其中一级路10公里(含6.3公里的水泥路面),二级路218公里,均为沥青混凝土路面。这些公路担负着较繁重的交通流量,因此,养护好这些公路,使之经常处于良好状态,以保证汽车安全、快速、舒适地运行,提高社会运输效益,有着十分重要的意义。这些公路,虽经过周密设计,精心施工,但难免存在某些不足和缺陷,加之自然和行车的作用,不可避免地出现不同程度的病害。因此,认为一、二级公路不会有太多养护工程量,
In order to meet the needs of economic development, our city has completed 228 km of primary and secondary roads on the national and provincial highways since 1983, of which 10 km (including 6.3 km of cement pavement) of Grade I and 218 km of Grade II , Are asphalt concrete pavement. These roads are subject to heavier traffic flow. Therefore, it is of great significance to maintain these roads so that they are always in good condition so as to ensure the safe, fast and comfortable operation of the vehicles and to enhance the social transport benefits. Although these roads are well-designed and well-constructed, it is inevitable that certain shortcomings and deficiencies will inevitably exist. Coupled with the natural and vehicular traffic, diseases of different levels will inevitably occur. Therefore, it is considered that there will not be too many maintenance projects for Grade I and II highways,
