Seasonal Variations Of Pavement Layer Moduli Determined Using In Situ Measurements Of Pavement Stress And Strain, Lauren J. Swett

Electronic Theses and Dissertations

Pavement design procedures have advanced a great deal in recent years, changing from empirical equations based on road tests in the 1950s to mechanistic-empirical design procedures developed in the past few years. The resilient moduli for the asphalt and soil layers of pavement sections are important properties necessary for pavement design, and an accurate method for determining moduli under different conditions is necessary. The stiffness of pavement section layers changes with the season, and typically, a road section will be the weakest during spring thaw due to loss of frozen soil stiffness, and increases in water content. This is critical …
