A novel mechanistic model based on an infinite beam on elastic foundation is developed to
quantify the impact of pavement structural and material properties on pavement deflection and consequently on
vehicle fuel consumption. The model can also account for the effect of temperature and vehicle speed on fuel
consumption. A simplified expression for evaluating the energy dissipation for practical purposes is proposed
and used to investigate the impact of various pavement design systems on fuel consumption. GPS (General Pave-
ment Studies) sections from the FHWA’s Long Term Pavement Performance program (FHWA 2011) are used
for this study. These sections consist of asphalt concrete (AC), portland cement concrete (PCC) and composite
pavements. The model quantifies the impact of temperature and vehicle speed on the fuel consumption and
confirms that those impacts are negligible for PCC and significant for AC pavements due to their viscoelasticity.
