摘要：

In order to reveal the influencing mechanism of hot mixed asphalt-mixture (HMA) surface texture on skid-resistance and noise reduction performance of asphalt pavement, spectral analysis method was used to obtain the level of HMA surface texture corresponding to each wavelength of central frequency in Octave. The relationship between indices of level and distribution of HMA surface texture and coefficient of friction, tire/pavement noise were analyzed by indoor experiments using two-dimension image texture analysis method (2D-ITAM), dynamic friction tester (DFT), and indoor tester of tire/pavement noise with an accelerated down-rolling tire. Results show that the level of characteristic wavelength can represent the level and distribution of macro-texture and mega-texture in short wave band. There are very well correlations between the level of characteristic wavelength and the coefficient of friction of vehicles with ABS system, tire/pavement noise of asphalt pavement. © 2017, Zhejiang University Press.
