Acoustic Models for Dense- and Open-Graded Asphalt Pavement

Abstract:

Empirical acoustic models were developed for dense-graded and open-graded asphalt concrete. Tire/pavement noise data were collected from in-service flexible pavements at different frequency bands for four consecutive years. These data were panel structured, and with a portion of observations missed arbitrarily. A Monte Carlo Markov Chain (MCMC) sampling and a multiple imputation (MI) algorithm were used to capture the unobserved heterogeneity and deal with missing observations by Bayesian simulations that are associated with the data. Models for the two mixes at different frequency bands were constructed. Major findings of the study include: first, tire/pavement noise increases with age at all frequency bands; second, tire/pavement noise level increases with air-void content of the surface mixes at medium and high frequencies but decreases at low frequencies; third, tire/pavement noise level increases with mean profile depth (MPD) at low and medium frequencies but decreases at high frequencies; and fourth, open-graded mix has low noise level compared to its dense-graded counterpart.
