Laboratory evaluation method of tire-pavement noise deterioration combining Rolling Tire down Tester with accelerated abrasion machine

•Impacts of microphone positions were analyzed, and two-side placement method is recommended.•Repeatability of the RTT noise tests considering tire landing positions and RTT noise variability was investigated.•Impacts of abrasion cycles on abrasion effects were analyzed and when to terminate was determined.•The overall noise level increases with abrasion cycles and a linear relation between them exists.•Spectral difference in 1/3 octave band after different abrasion cycles is in frequency above 1000 Hz. Tire-pavement noise and its durability have long been investigated by onsite observations. This research aims to explore a laboratory evaluation method of tire-pavement noise deterioration that combines the Rolling Tire down Tester (RTT) with the accelerated abrasion machine. Firstly, microphone placement was determined and repeatability of the laboratory RTT noise test method was evaluated, considering tire landing positions and RTT noise variability. Secondly, impacts of abrasion cycles on abrasion effects were analyzed based on the selected multi-variable accelerated abrasion machine (MAAM). Finally, noise deterioration characteristics were investigated combining RTT with MAAM. Placing microphones on two sides is recommended and the abrasion is terminated after 24,000 abrasion cycles. Overall noise level arises with increasing abrasion cycles, and linear correlation exists. The laboratory changes of noise level, 1/3 octave band spectrum, and noise growth rates are generally consistent with previous research, demonstrating feasibility of evaluating noise deterioration combining RTT with MAAM.
