Laboratory Investigation of Seasonal Variations in Resilient Modulus of Alaskan Base Course Material
In Alaska, granular base course materials, typically known as D-1 aggregate materials, undergo significant changes in resilient properties due to seasonal conditions. In the springtime, saturated base course materials are weakened due to thawing, resulting in reduced resilient properties. This paper investigates seasonal effects on the resilient modulus (MR) of a D-l material from southeast Alaska. Experimental work was performed on a granular material to investigate the impact of fines content, moisture and temperature on its resilient modulus. A frost heave/freezing cell was designed to condition soil specimens prior to resilient modulus testing. Depending on its thermal state, two separate prediction models were used to estimate MR of the D-l material.
