N2 - Contraction joints between sections of Portland cement concrete pavement have a significant effect on measured tire-pavement noise levels. Previous work has shown that tire-pavement noise levels increase with joint width and depth. It has been proposed that during the interval when the contact patch of the tire covers the joint, the system acts as a half-wavelength 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. Microphones were used to measure noise near joints under varying conditions using Purdue University's Tire-Pavement Test Apparatus (TPTA). It was determined that the resonance mechanism is the dominant mechanism for treadless tires, but that the mechanism is less important when treaded tires are used.
