technical field
[0001] The invention relates to a timely evaluation method for road surface quality, in particular to a method for estimating the service life of asphalt pavement from the smoothness of the road surface. Background technique
[0002] With the increase of traffic volume, the proportion of pavement damage caused by permanent deformation is increasing: for example, in the United States, the survey of pavement damage in various states initiated by AASHTO in the 1970s showed that on major interstate highways, due to permanent deformation The resulting pavement damage accounts for about 30%, while Japan's statistics in the 1980s showed that the pavement damage caused by permanent deformation was as high as 82%. In my country, since the "Eighth Five-Year Plan", the problem of permanent deformation has become more and more serious, and permanent deformation has become a worldwide problem in the crown of the three major damage forms of asphalt pavement. Permanent def...
