The Extraction of Rutting Transverse Profiles Indicators Using 13-Point Based Lasers
Through analyzing the data collected by the 13-point based laser bar,the original rotting transverse profile is built in this paper.The angle rotation method and cubic spline interpolation method are then adopted to rotate and smooth the profile to get the standard figure of rutting transverse profile.The rotation processing eliminates the effects of crown slope on rutting profiles, and the smooth processing makes rutting profiles be more similar to the real pavement profile.Based on the comparison of straight-edge and wire-line rut depth calculation methods, the wire-line method is used to acquire the 1D rut depth and rut width.The trapezoidal integral rule is utilized to calculate the 2D rut positive area and negative area.Results show that the indicators extracted in this paper can describe the rut more comprehensively and accurately.
