Three-dimensions texture reconstruction of asphalt pavement based on MATLAB

Among the many characteristics of asphalt pavement performance, the mean texture depth (MTD) is one of the most important features, because it is the most important factor reflecting skid resistance and driving safety of the pavement. The purpose of this paper is to study the use of MATLAB to reconstruct the three-dimensional texture of asphalt pavement surface. The MTD of SMA wheel rutting test slab specimen has been measured by laboratory test, the 3-dimensional texture model of SMA wheel rutting test slab specimen's surface has been reconstructed by digital image processing technology in this paper. Results indicate that According to the measured texture depth, the effectiveness of models was then examined.
