Title:
Effects of Multiple Freeze Cycles and Deep Frost Penetration on Pavement Performance and Cost
Abstract:
Understanding deterioration of pavements exposed to climates with multiple freeze-thaw cycles as compared to climates with sustained deep-frost penetration is important to State Highway Agencies (SHAs) across the country. Consideration must also be given to differential performances between pavements in these freezing climates and those in nonfreezing areas. This report documents a study conducted to evaluate pavement deterioration in various environmental settings. In addition, it documents local adaptations currently in use to mitigate frost-related damage along with the cost differences associated with constructing and maintaining pavements in the various climates. Performance models developed from the Long-Term Pavement Performance database were used to predict and compare performance in various environments. As demonstrated in the report, the prediction models are also an important tool in the calibration process outlined in the National Cooperative Highway Research Program (NCHRP) Guide for Mechanistic-Empirical Design of New and rehabilitated Pavement Structures as well as in pavement management applications for SHAs with limited quantities of regional performance data.
