Title:

Pavement-Vehicle Interaction and Comparative Highway Fuel Consumption: Extended Field Investigation

Accession Number:

Record Type:

Component

Abstract:

Pavement-Vehicle Interaction (PVI) describes the effect of pavement structural and surface properties on vehicle fuel efficiency. Direct comparison studies have been carried out previously by the authors on two pairs of flexible-rigid roadway sections at two interstate highways in Florida. Averages of 2.50% and 4.04% fuel savings were found on rigid pavement section compared to each paired flexible pavement section for passenger car and 18-wheel tractor-trailer. This study further investigated the effect of pavement type on vehicle fuel consumption with a more comprehensive and parametric experimental design. A middle-size passenger car and a medium-duty box truck were operated at two speed levels on multiple highway sections selected in Florida. Fuel consumption was measured and recorded along with other important environmental/vehicular information. Collected data were analyzed with Analysis of Covariance (ANCOVA) test to detect the significance of pavement type on fuel consumption by excluding the influence of pavement surface properties. Results revealed statistically significant differences between flexible pavement (group) and rigid pavement (group) for both passenger car and truck. Fuel savings of 2.25% and 2.22% were found on rigid pavement (group) compared to flexible pavement (group) for passenger car at 93 km/h (58 mph) and 112 km/h (70 mph), and savings of 3.57% and 3.15% were found for truck at 89 km/h (55 mph) and 105 km/h (65 mph). The findings exhibit good agreement with the authors’ previous study despite the differences in experimental design and study methodologies.
