Abstract/OtherAbstract:
Contraction joints between slabs of Portland cement concrete have a major impact on measured tire-pavement noise levels. It has been proposed that during the interval when the contact patch of the tire is over the joint, the system acts as a Helmholtz resonator, and that this mechanism is responsible for the majority of the increased noise due to contraction joints. In this paper, this mechanism is investigated through theoretical calculations and experimentation. Intensity probes were used to measure noise near joints of varying widths using Purdue University's Tire-Pavement Test Apparatus (TPTA). The TPTA was used to discover relationships between vehicle speed, joint width, and measured sound pressure and sound intensity spectra near the joint and the tire.
