HOT-MIX ASPHALT TRACKBEDS : THE U.S. EXPERIENCE ---PROCEEDINGS OF THE THIRTY-SECOND ANNUAL CONFERENCE OF THE CANADIAN TECHNICAL ASPHALT ASSOCIATION

During recent years trackbeds containing a layer of dense graded hot-mix asphalt have been constructed for experimental evaluations and to solve specific soft roadway/pumping problems. The overall purpose is to evaluate the performance and long term economic benefits of the system under widely varying traffic, roadbed and environmental conditions. Commonly, the asphalt layer is placed directly on new subgrade or old roadbed with a layer of regular ballast placed on top of the asphalt. Track modulus tests indicate consistent values of track stiffness which is near optimum. Asphalt trackbeds have the potential to provide increased operating efficiency and decreased maintenance costs which should result in long term economic benefits for the railroad and rail transit industries.
