Pavement Surface Characterization for Optimization of Trade-off between Grip and Rolling Resistance

项目名称：	Pavement Surface Characterization for Optimization of Trade-off between Grip and Rolling Resistance
摘要：	Multi-scale understanding of the contact deformation behavior between pavement and tires within the contact patch is necessary in revealing the mechanism of rolling resistance, grip and sound analysis. Here, the project will assemble a multi-scale framework to optimize the pavement texture to reduce the rolling resistance without sacrificing grip. Since rolling resistance in high speeds appears to be dominated more by macro-scale parts of a pavement profile, and grip in low speeds is affected more by small-scale asperities, the project is looking for a meso-scale surface spectrum (0.5-200 μm) that minimizes rolling resistance and maximizes grip. The main idea here is to design a surface profile to balance the trade-off between friction, adhesion and hysteresis. Viscoelastic behavior of rubber is the key here since it theoretically gives us two different material behaviors at low and high speeds, which can be used to optimize profile of surface asperities, accordingly.
