Abstract:The highway construction industry is changing rapidly. With most of the interstate systems completed, the scope of work is now focusing on maintaining the existing systems. Because of the differential time between beginning and completion, many sections are approaching the end of their original design life. Some of these have already had maintenance action and many are presently in need. Many pressures are being brought to bear as to the type of maintenance that should be performed. Fiscal and environmental are probably the most influential pressures being levied. Highway designers are now having to consider many different alternatives and the impact of each of these alternatives. One of these new alternatives is recycling. Recycling of asphaltic concrete pavements promises to satisfy the concepts of fiscal and environmental savings. A major recycling project on Interstate 8 was studied to evaluate the savings of this alternative. In addition to this, an extensive evaluation of the recycled asphaltic concrete has been conducted and will continue in the future to determine its long-term characteristics. This paper reports on the findings to date.
