PAVEMENT-VEHICLE INTERACTION II

In its “PVI Mechanistic Model Gen II” research brief (December 2013) CSHub extends earlier observation of pavement-vehicle interaction, which impacts truck fuel consumption and, in turn, concrete and asphalt life cycle assessment. The new model can account for the impact of temperature and vehicle speed, plus other pavement structural and material properties, on fuel consumption, and is thereby applicable to viscoelastic (e.g. asphalt concrete) pavements. Model Gen II provides what CSHub staff affirms is “a rigorous tool for comparative studies and LCA of the roadway network.”
