Abstract

Pavement texture is an important parameter in tire-pavement-interaction- noise (TPIN). As pavements carry traffic load over the years measurable degradation occurs in texture. The Implication of texture degradation is related to changes in tire pavement interaction noise and friction. As the pavement is exposed to environmental and traffic elements, changes occur in ride quality measured by the International Roughness index (IRI) as well as the Surface Rating (SR). Research investigated the correlation between Tire Pavement Interaction Noise (TPIN), Estimated Single Axle load (ESAL); surface Rating and age of pavement in MnROAD test cells. General observation shows decrease of OBSI with respect to traffic evidenced in the relative values of driving and passing lane in the rigid pavements and conversely an increase in OBSI in the bituminous segments. An initial overall model of all the cells was not feasible as various pavement types exhibited unique characteristic residuals. This led to the development of individual models for each surface type. No tenable relationship between Friction Number (FN) and TPIN was established. Texture degradation exhibited non-linear characteristics with respect to the Pavement age ESALS IRI and SR.
