Pavement Design Using Unsaturated Soil Technology

Principal Investigator:

April 2009

Report no. 200711TS

Topics: Pavement design for cold climates

A new method of using the principles of unsaturated soil mechanics during pavement design was developed. This will allow pavement engineers to better take into account field conditions and seasonal variations in moisture content. The new models developed in this study allow pavement designers to estimate the stiffness and strength of any soil encountered in the field.
