As a part of the Long Term Pavement Performance (LTPP) Seasonal Monitoring Program measures of electrical resistance have been used to monitor frost conditions at selected LTPP test sites. The raw data from the pavement instrumentation have been available in the LTPP database for some time. However, to be useful in engineering analyses, the raw data must be intel preted to derive estimates of frost and thaw penetration depths. This report documents analysis conducted to develop and apply procedures for interpretation of the raw data. The "computed parameters" derived through this analysis have been added to the LTPP database.

This report will be of interest to those who wish to use the LTPP seasonal monitoring data, and to other users (or potential users) of similar technology for monitoring frost conditions.
