Reuse the Abused: As Roads Deteriorate and Costs Rise, Benefits of Asphalt Recycling Become More Apparent

In an article on recycling innovations, using recycled asphalt in paving is described. The most common methods, cold planing, cold in-place recycling, hot recycling, hot in-place recycling and full-depth recycling, are used almost equally, depending on conditions. Full-depth reclamation seems most common in the southeastern U.S. because of the poor state of many roads. Research to explore methods to use other recycled materials, such as coal fly ash, is also underway. A test section of four miles of pavement that was studied is also described. Fly ash, lime or lime-kiln dust and other materials were tested in base layers.
