Portland Cement Concrete Pavement Best Practices Summary Report
This report summarizes the work and findings from WA-RD 744. This work consisted of four separate efforts related to best practices for portland cement concrete (PCC) pavement design and construction: (1) a review of past and current PCC pavement, (2) an analysis of PCC pavement studded tire wear on the WSDOT network, (3) a life cycle assessment (LCA) of PCC pavement rehabilitation options and (4) an analysis of the effects of loop detector installation on PCC pavement life. Key findings are: (1) outstanding issues to resolve with PCC pavement include the impact of smaller maximum aggregate size, new dowel bar materials, and shorter joint spacing, (2) there is no effective means to mitigate studded tire wear, (3) stud wear is typically in the range of 0.04-0.09 mm/yr but tends to occur more quickly early on in pavement life, (4) excessive stud wear problems are limited and not a widespread issue, (5) an aggregate hardness program like Alaskas can help ensure stud wear does not become a major issue on newly constructed pavements, (6) life cycle assessment (LCA) can be a useful information tool and tends to show that crack, seat and overlay rehabilitation of aged PCC pavement provides many environmental advantages; and (7) current loop embedment practices do not seem to affect pavement life however previous practices may have.
