Experimental and Numerical Investigation on Roughness-Related Pavement Damage Progression

Rational methods of pavement design evaluate structural response by referring to the multi-layered elastic model, while traffic loads are considered as moving constant forces. However, road roughness originates inertial effects in vehicles that result in random fluctuations of wheel loads around their static values. This aspect of vehicle-pavement interaction has been already addressed by the Authors who developed a measuring system for the characterization of road roughness and of its effects on vehicles. In this work, measurements provided by the device were used for deriving a methodology which takes into account the dynamic nature of vehicle loads within the analysis of pavement damage progression. Experimental data were interpreted by referring to the quarter-car mathematical model used in combination with the multi-layered elastic model to evaluate pavement structural response. The rate of reduction in pavement service life with respect to the assumption of constant moving loads was calculated by referring to several distress models for different pavement roughness conditions, cross sections, vehicle types and travel speeds.
