An Experimental and Numerical Study of Tire/Pavement Noise on Porous and Nonporous Pavements

Abstract

This present research assesses tire/pavement noise by analyzing and comparing noise data acquired from low noise pavement (Asphalt Rubber Concrete) and conventional pavement (Asphalt Concrete). Close Proximity (CPX) tests are employed in this research to acquire the tire/pavement noise generated from the test pavements. A numerical simulation model established via the finite element method is conducted to simulate the noisegenerated by the impact mechanism, which is observed from the CPX test on both the test pavements. The simulated tire/pavement noise pressure levels are compared with those tested to verify the reliability of the numerical model.
