In recent years, there has been an increased interest in conservation of our resources, preservation of our environment and maintaining our ecology. Recycling of materials is a procedure that will immediately contribute to all of these desirable end results. Our economy is built on private enterprise and profit incentive and in the past, with abundant inexpensive resources, there was little incentive to recycle. Shortages of materials and energy (once considered abundant) along with regulations to protect the environment have emphasized the need for recycling. These environmental conditions coupled with the loss of purchase power by inflation has generated more interest in recycling in the transportation field. The Iowa Department of Transportation (Iowa DOT) is interested in recycling portland cement concrete (pcc) pavement to: 1. Provide aggregate where high quality aggregate is no longer economically available. 2. Eliminate the need for locations to waste the large amount of pavement rubble. 3. Conserve the present aggregate sources. 4. Reduce the need for disrupting land for quarrying purposes. 5. Save fuel and energy by reducing aggregate transportation.
