SEASONAL STRENGTH OF PAVEMENTS

Reduced strength due to frost action in highway pavements is a well recognized international problem. This paper discusses causes for this reduced strength in general, summarizing reported research findings in the United States on changes in subgrade moisture and density, pore pressures due to solar heating of the pavement, measurement of seasonal strength changes and design and construction methods for minimizing these changes. The author suggests improvements in drainage of pavements which may be useful for reducing the problem of strength loss during the spring thaw. /Author/
