Evaluation of Frost Related Effects on Pavements

This report describes the field data and analysis techniques used to evaluate the effect of winter ground freezing on WSDOT pavement structures during two thaw periods. Six field test sites were selected in District 2 for deflection testing and in situ instrumentation as well as materials sampling.

The results show that a principal mechanism which necessitates load restrictions for some of the WSDOT pavement structures is the weakened condition of the base course during thawing periods. Presented in the report is a single revised load restriction table and a criterion to use in determining the time that load restrictions should be established.
