Seasonal Weight Restriction Decision Making Based on Understanding and Monitoring of Frost Susceptibility of Pavement Structures

This study aims to critically assess the variation of stiffness, temperature and moisture throughout the base and subbase structure to better determine the capacity of roads as the seasons transition from winter to spring. The objectives of this project are to critically assess the variation of temperature, moisture, stiffness and strength throughout the base and subbase structures during different driving seasons to better determine the capacity of roads from winter to spring to summer driving seasons. And propose an interpretation and analysis protocol of continuously collected data to create a decision-making process for the frozen road declaration, midseason thaw, ending the frozen road declaration, and imposing and ending spring weight restriction in the State of Wisconsin.
