A Comparative Study on Noise Reduction Ability of Rubberized Pavement with Conventional Pavement.

In the recent years, number of vehicles and roads are increasing exponentially. Noise pollution has been a concern among the publics and currently there is an up rise regarding the health and mental issues that might result from it. Thus the result, various development solutions such as softer tires, noise dampening barriers and new quiet pavement materials has been introduced. One of the new pavements introduced is rubberized pavement. Based on various researches around the world, rubberized pavement has the potential of reducing noise generated from tire-pavement contact. To date, a few rubberized pavement roads have been constructed in the country. However, the performance is yet to be evaluated. Therefore, this study was proposed to evaluate the noise reduction ability of rubberized pavement in Malaysia. This study will be carried out by performing test run on both rubberized and conventional pavements. Two field test methods have been proposed namely pass-by method and cruising method. Eventually, the result of the study shows that rubberized pavement produced relatively lower noise level as compared to conventional pavement. However, the reductions in noise level were not significant to the hearing of the human
