Relating climate factors to pavement subsurface conditions Conference Paper

abstract

• A new approach is presented for relating climate factors to pavement subsurface conditions such as in-situ temperature and soil moisture state. The results show clearly that it is impossible to develop useful engineering relationships between climate factors and pavement subsurface conditions. Freezing index is used to characterize the severity of a winter and approximate the onset of freezing and the location of the thawing front. A strong moisture gradient exists within the granular base layer, contributing to slow drainage of the overall pavement system, the unfrozen moisture content is heavily dependent upon the layer temperature and temperature history.
