Title Information on Materials and Practices for Improving Highway Pavement Performance.
Publication Date Nov 2012
Media Count 21p
Personal Author N/A
Abstract Our literature review and discussions with stakeholders having relevant expertise resulted in the identification of 40 materials and practices that may contribute to improving the performance of pavements, extending service life, and reducing life-cycle costs. These materials and practices cover a range of uses and applications across the stages of a pavement's life cycle, from initial design and construction through maintenance and preservation cycles, and at the time of reconstruction. Several challenges exist to states' use of these materials and practices. In particular, some materials and practices may not be applicable or beneficial to all states, a decentralized and segmented highway industry may impede change, and resource constraints and procurement methods may limit states in implementing new approaches to building and maintaining their highways. However, FHWA, AASHTO, and states have developed several programs that address these challenges through research, training, and information and outreach programs.
