Description

Pavement vehicle interaction (PVI) is a concept that looks at the interaction between a vehicle’s tires and the roadway surface on which it is driving; also known as rolling resistance. Three factors relating to a road’s surface condition and structural properties contribute significantly to PVI: roughness, which refers to how bumpy or smooth a road is; texture, the abrasiveness of the road surface; and deflection, the bending of a pavement under the weight of a vehicle. Traffic patterns and temperature are influential factors as well.

PVI leads to excess fuel consumption (EFC), which is wasted fuel consumption beyond what is required to move a vehicle. EFC contributes to smog and greenhouse gas emissions, and impacts drivers, states, and municipalities financially. MIT CSHub research has led to models that quantify excess fuel consumption due to PVI for pavement segments and pavement networks.

Speaker(s)

Jeremy Gregoryis a research scientist in the Department of Civil and Environmental Engineering and the Executive Director of the Concrete Sustainability Hub (CSHub) at the Massachusetts Institute of Technology. He studies the economic and environmental implications of engineering and system design decisions, particularly in the area of materials production and recovery systems. Research topics include product and firm environmental footprinting, manufacturing and life cycle cost analysis, and characterization of sustainable material systems. Jeremy has applied these methods, often with industry partners, to a range of different products and industries including pavements, buildings, automobiles, electronics, consumer goods, and waste treatment and recovery. He received his PhD and MS from MIT and BS from Montana State University-Bozeman, all in mechanical engineering.
