Objective

This research will provide WSDOT with the most effective efficient methods of design and construction for use in PCCP design and rehabilitation/reconstruction.

Specific objectives are:
1. Determine the material types that will best provide for long-lasting pavements (dowel bar materials, cement properties, aggregate properties and base types).
2. Analyze the sensitivity of design details to pavement life in order to determine where expenditures of time and money can have the greatest impact.
3. Document of previous design and construction experience. Previously complete projects need to be documented, evaluated and disseminated.
4. Develop interactive self-directed training on these subjects for WSDOT in order to better disseminate information.

Project Progress

Completed Life cycle assessment of I-5 pavement reconstruction options.

New Period Proposed Activity

Submit reports for first two efforts related to this study (studded tire wear and LCA). Begin work on assessing pavement performance and costs associated with crack-seat-and-overlay rehabilitation of old concrete pavements.
