Estimation of the Rolling Resistance performance of a pavement in view of the roughness profile

The reduction of rolling resistance is essential for a more environmentally friendly transportation system, a process is highly influenced by both tire and pavement design. Here, the research team proposes to develop a systematic model to provide the correlation between the surface roughness of the pavement and the rolling resistance experienced by the vehicles. To this end, a multi-scale simulation model will be assembled to consider the pavement profile, the energy dissipation of tire and the complicated contact mechanism involved. In this work, the recently developed tire/pavement interaction model will be advanced to account for micro-and meso-scale pavement roughness and the energy losses due to the corresponding small-scale tread deformation. The correlation between energy loss and rolling resistance will be described using a ranking and rating system. Currently, direct formulation of such correlation is a complicated procedure that involves the mechanics of the vehicle and dynamics of the tire to be understood at multiple scales. In this work, tire-pavement contact will be simulated using finite element (FE) solvers with respect to a multi-scale visco-elastic model for rubber. By profiling surfaces up to few microns, the contact mechanism and the resulting energy dissipation will be concurrently modelled in micro-, meso and macro-scales for the first time.
