Finite element modelling and feedback

Asphalt airfield pavements degrade over time due to use, but regular maintenance can extend their service life. Cracks that form in the pavement must be sealed to prevent water from getting in and increasing the deterioration. Among possible solutions to delay cracking is the use of polyester geogrid placed between an existing layer of pavement and a new asphalt overlay. An asphalt reinforcement polyester geogrid extends pavement life and requires maintenance less often. This article describes numerical simulations of reflective cracking in asphalt concrete pavements that have been reinforced with polyester geogrid in order to better understand the behavior of polyester geogrid.
