Improving the Fatigue Properties of Flexible Pavement with Polymer Modified Asphalt (PMA)****

点击翻译按钮获取中文摘要

Fatigue is one of the major modes of deterioration of flexible pavements in Canada. The use of polymer-modified asphalt cements (PMA) would improve the durability of asphalt mixes using in pavements and extend their service life. This project is a collaboration between Yellowline and the Centre for Pavement and Transportation Technology at the University of Waterloo. The two partners will work closely to evaluate the binder and mixture performance of several PMA formulations with varied polymer types and contents, different cross linking agents and integration techniques. Different standard and innovative test methods will be used in this study in order to develop a tool kit that will help Yellowline formulate the most effective PMAs and predict the fatigue performance based on the binder and the mix properties. The results will help optimising the PMA formulations as will provide a fundamental scientific insight that can be used to improve PMA practice in general.**
