WASHINGTON STATE DEPARTMENT OF TRANSPORTATION'S FIRST ASPHALT CONCRETE RECYCLING PROJECT - RENSLOW TO RYEGRASS

This asphalt concrete recycling project, the first attempt by the Washington State Department of Transportation, seems so far to be very successful. The project looks good from a standpoint of economy, energy use, conservation of natural resources, feasibility of construction, and from an evaluation of the test data obtained to date. Certain pitfalls seem to exist when using this type of a recycling process, such as selection of the proper rejuvenator, degrading of the aggregates, pollution, proper amounts of new aggregate, and other minor problems. Properly conducted preliminary testing and design can avoid a multitude of these pitfalls. Future asphalt concrete recycling will most likely be a definite consideration in the rehabilitation of asphalt concrete highways in Washington. In fact, one project has already been scheduled for recycling in 1978 construction, with a number of additional pavements being considered for 1979 construction.
