| Highway agencies are faced with the challenge of maintaining pavement infrastructure, which is crucial to both economic and social activities. The overlays using Asphalt Rubber Mixture (ARM) have evolved as an effective rehabilitation strategy over the last four decades. In the summer of 2002 and 2003, pavement sections using ARM were paved in Alberta to investigate the effectiveness of ARM in Alberta weather condition.; This thesis presents the performance evaluation of the 2002 and 2003 Alberta Asphalt Rubber pavement sections. The performance evaluation of more than ten asphalt rubber pavement sections, laid in 2002 and 2003, are discussed.; A laboratory experiment was conducted at the University of Alberta to reconfirm the 2003 ARM design and to investigate the moisture resistance of ARM. The laboratory experiment revealed open-graded ARM to be more prone to moisture damage compared to dense-graded ARM. |
