Enhancing the Durability of Asphalt Pavements. Papers From a Workshop. Held in Washington, DC on January 13, 2013

摘要

In the past several years, there have been a number of significant advances in asphalt materials and construction techniques for increasing the durability of pavements. This e-circular contains papers based on a Sunday workshop at the 92nd Annual Meeting of the Transportation Research Board in Washington, D.C., on enhancing the durability of asphalt pavements. The workshop focused on new design and construction approaches for extending pavement life while also improving their sustainability. The workshop also addressed the use of new materials, methods of mix analysis and cracking models, coupled with specific construction techniques that can significantly increase the life of the asphalt pavement. Furthermore, it covers actual application of these materials and approaches and some associated long-term benefits. The most significant outcome of this workshop was to show that these materials and approaches are readily available in the marketplace today and only require some relatively minor changes to specifications.
