Background In pavement structural design, each structural layer plays a critical role in overall pavement stability. According to the statistics of related data, large-scale disease phenomena such as pits and cracks appear on a large number of roads under the condition that the design service life is not reached. Most of these defects result from the fact that the thickness of the pavement structural layer does not meet design criteria or other structural defects exist, which in turn results in a significant reduction in pavement load carrying capacity. Meanwhile, the occurrence of diseases greatly increases the later maintenance and repair cost, and causes resource waste and traffic running efficiency reduction. In order to effectively prevent the occurrence of the disease problem and reduce unnecessary operation and maintenance investment, standardized detection and evaluation of the construction quality of a road surface structural layer are needed in road engineering.
