Effect of temperature on asphalt pavement strain responses: APT data and thermo-viscoelastic pavement modelling

Résumé

This paper presents data and modelling results of asphalt pavement strain responses for different pavement temperature conditions. The tensile strains developed at the bottom of the structural layers in a thick asphalt pavement are critical to the thickness design. Measured strain data have been collected during a pavement response to load experiment undertaken using the IFSTTAR's accelerated pavement testing (APT) facility. The effect of the pavement temperature on the tensile strains at the bottom of the asphalt layers is derived from the data in different pavements structures, at different speeds and for different wheel configurations in both the longitudinal and transverse directions. A thermo-viscoelastic pavement response to load model has also been used to evaluate strains. When comparing measured strains with calculated strains, the viscoelastic model is found to provide a good agreement with the APT strain signals.
