Abstract:This paper studied the correlation between pavement texture and skid resistance through analysis of three-dimensional texture information of pavement. In the experiment, high-precision pavement texture acquisition equipment was used to extract the three-dimensional texture information of the AC-13 and AC-16 asphalt rutting plate test specimens. Then, the optimal noise reduction smoothing model based on the Ensemble Empirical Mode Decomposition (EEMD) algorithm was used to filter and denoise the three-dimensional texture information of the rutting plate test specimens, and the three-dimensional reconstruction is carried out. Then, the intrinsic mode function IMFs is obtained by means of the Complementary Ensemble Empirical Mode Decomposition (CEEMD) algorithm to decompose two-dimensional texture signals. Meanwhile, the IMF that exhibits the strongest correlation with the original signal is chosen for application of the Hilbert Transformation, which facilitates the extraction of instantaneous frequency and amplitude. At last, is introduced as an index to assess the anti-sliding performance. The experimental results show that the correlation coefficients of and pavement friction coefficient is above 0.8. can be used to good characterize the skid-resistance performance of the pavement.
