Abstract
In this paper, a new type of noise-reducing pavement, porous elastic low-noise pavement, was developed, and the effect of voidage and elasticity on noise reduction was studied experimentally. Three kinds of standard test pieces of mixed material-derived rutting plates with different voidage gradations were designed, and the laboratory tire acceleration fall test and damping vibration and noise reduction test were carried out. The results show that the porous elastic low-noise pavement has better noise reduction ability than ordinary asphalt concrete pavement. The noise reduction ability of the two methods is strong, compared with that of the traditional densely graded AC-13 asphalt concrete. With the increase in the new material dosage, poly olefin elastomer (POE), the system damping of tire/road becomes larger. The enhanced vibration and noise reduction ability can provide a suitable theoretical reference for the application of POE materials and pavement engineering in the aspect of noise reduction.
