Title:
Thermal Aspect of Frost-Thaw Pavement Dimensioning: In Situ Measurement and Numerical Modeling
Abstract:
The thermal behavior of pavements in winter has a major influence on their dimensioning. The Paris-based Laboratories Central Des Ponts et Chauss'ees (LCPC) and the ministe're des Transports du Quebec (MTQ) have models to forecast the propagation of frost, frost heave and thaw phenomena. They have developed a collaborative project to validate these models on an experimental pavement. This pavement was constructed in Quebec in 1998 and its thermal behavior was monitored for three years. This paper presents the assessments of the thermal models. It describes the models, site and the temperature conditions of the three winters, pavement structures and their physical properties, instrumentation set up, and the analysis and comparison of the results of the models among themselves and in relation to the observations conducted on the pavements.
