A highway tractor with a van semi-trailer and a passenger car were driven over concrete, asphalt and composite paved roads to detect if fuel savings could be attributed to any of the three pavement surfaces. The tests were conducted in winter, spring, summer cool, summer hot and fall weather conditions and at two road speeds: 60 km/h and 100 km/h. Additionally, the trailer was loaded to three different weights to establish if loading was a contributing factor to fuel consumption differences among pavement types. All testing was performed on open highways in Ontario and Quebec. The acquired data were then analysed using multiple regression which formed the basis for a set of predictive mathematical models. A number of conclusions regarding the relationship between pavement type and fuel efficiency were drawn from these models.
