【Abstract】：The thickness of asphalt concrete pavement is one of the most important indicators of asphalt pavement quality evaluation. In order to evaluate the construction quality of pavement thickness scientifically， reasonably， and accurately， the evolution of asphalt pavement thickness evaluation methods is reviewed. This paper points out the shortcomings of the current evaluation system， analyzes the causes of unqualified asphalt pavement thickness based on actual engineering， and proposes methods and suggestions for quality control during construction.
