A three-month research project was conducted on the frost heaving patterns of a culvert. Problems are typically encountered when such a culvert is placed under a road in a frost-susceptible soil. Major differential frost heaving is produced and has a negative effect on the structure of the road itself while creating a rough ride and reducing safety for road users. This project analyzes the performance over the winter period of several potential remedial designs. The goal is to find a design that will minimize the differential frost heave for the broadest possible conditions in terms of frost-susceptibility and of freezing pattern.
