Comparison of the response of an instrumented pavement section under individual and platoon truck loading

Résumé

Trucks transiting in platoon configurations promise a reduction in traffic congestion, an improvement in road safety, as well as lower fuel consumption and greenhouse gases emissions. Considering that truck platoon configurations are new, it is necessary to describe the structural responses they can produce in the pavement. In this sense, the present study shows the results obtained from a fullscale experiment designed to evaluate the structural responses of a test track subjected to the passage of trucks under two configurations: individual and platoon. The experiment consisted of measuring the transversal and longitudinal strains produced at the level of the bituminous layers of the pavement structure when trucks under both test configurations are transiting at speeds of 40 km/h, 60 km/h, 70 km/h, and 80 km/h. In order to consider the weather influence, two test campaigns were performed, one during winter and the other in summer. The main conclusion of the study is that by managing inter-vehicle distances, truck speeds, wandering, time, and periods of circulation, it is possible to minimize the impact of truck platoon configurations on the pavement's structure performance.
