自改革开放以来,我国的公路建设快速发展,高速公路和国道的里程数逐年增加。与此同时,城市公共交通逐渐趋向成熟;大量私家车的出现;大型集装箱运输量增加,这对于各地的公路质量是一个严格的考验。由于早期技术的不成熟,现存许多公路路面的施工质量较低,在巨大的交通压力下,必须提高公路罩面的施工质量,并修整已经遭到破坏的路面。
Since the reform and opening up, China’s highway construction has been developing rapidly, and the mileage of highways and national highways has been increasing year by year. At the same time, urban public transport has become more and more mature; the emergence of a large number of private cars; and the increase of large-scale container traffic have been a severe test for the quality of highways all over the country. Due to the immaturity of earlier technologies, many existing road pavements have a low quality of construction. Under enormous traffic pressure, it is necessary to improve the construction quality of road coverings and to trim damaged pavements.
