Abstract :

Background and Objective:  Noise pollution caused by vehicle traffic is one the important problems in the urban areas.  As the cost of construction and installation of acoustic walls to prevent the noise pollution is high, dealing with this problem needs to follow the techniques that will increase the cost of the implementation on roads. Improving the pavement texture of the superstructure is one of the methods which is very effective in order to reduce the noise of tire and road surfaces and reduce sound reflection from the surface of the asphalt. Method: For the evaluation of asphalt resistance test is in accordance with ASTM English standard pendulum E303-74 in wet conditions on the different parts of the asphalt. Findings: The number of friction road surfaces with a coefficient of negative noise level compared with the amount of 0.1469, i.e. by increasing the number of friction road surfaces will reduce the amount of created noise level. As well as the depth of the texture of the road surfaces that form the superstructure materials fitted size is designated with a direct proportion with the amount of pollution 0.2810 which is coefficient for the sound created and any size from fine-grained materials will increase the amount of sound level. Discussion and Conclusion: According to the results of the estimated coefficients from the equation, it can be found that in the hands of the preparation of road surfaces with high friction number can release the noise pollution level including the noise of moving vehicles, especially in urban areas and sensitive areas. It is therefore advisable the sensitive areas to be in the process of preparation of the superstructure and maintain the order adopting the proper resistance of road surfaces and the coarser materials.
