Laboratory Investigation of Cracked Asphalt Pavement Structure Using Accelerated Loading System
During winter season, cold temperatures will promote the development of tension stresses in the hot-mix asphalt (HMA) layers which can, in turn, lead to the occurrence of low-temperature cracking. Although the mechanisms and factors fostering the appearance of low-temperature cracks are already well understood, the consequences of this degradation on the structural capacity and freezing behavior of the pavement structure near the crack are still poorly documented. The purpose of the present project is to improve the state of knowledge regarding the effects of cracking on pavement performance. This paper documents the methodology undertook to investigate the mechanical behavior of a cracked asphalt pavement structure subject to varying thermal and dynamic load cycles. The pavement structure was built in the indoor test track pit of Université Laval in which an idealized transverse crack has been created in the HMA layer. Cyclic loading of the structure was accomplished using the Accelerated Transportation Loading System (ATLAS). The mechanical response of the pavement structure is monitored using different types of strain gauges (H-gauges, optic fiber gauges) and pressure cells embedded at precise locations in the different pavement layers with a particular interest for the area around the crack. Strain and stress levels measured around the idealized transverse crack are compared with those of a crack-free area.
