Abstract
noise from the vehicle aerodynamic effect, and noise from the interaction of the tire and the pavement. One of the most effective factors in creating tire/pavement sound and reducing the sound of reflection from the asphalt surface are: pavement texture, pavement life, vehicle speed, and temperature,pavement texture should have adequate sliding resistance at high speeds. Because one of the effective factors in reducing accidents and increasing safety is to improve the surface friction of the pavement. To evaluate the skid resistance of asphalt, the English pendulum test by EST3-74 ASTM standard in wet and dry conditions was used. T According to the results, it can be concluded that the preparation of pavements with a higher percentage of coarse grain, can increase friction by 32% and increase noise pollution by 6% due to the movement of vehicles. Increasing the speed also increases the pavement/tire noise by 0.9 dB. Compared to weather conditions (wet and dry asphalt), the slip resistance of wet asphalt decreased by 6%, and the amount of noise (pavement/rubber) in wet asphalt compared to dry asphalt increased by an average of 1 dB.
