Abstract:

Resilient modulus (MR) of base course material is an important material input for pavement design. In Alaska, due to distinctiveness of local climate, material source, fines content and groundwater level, resilient properties of D-1 granular base course materials are significantly affected by seasonal changes. The presence of fines (P200) affects frost susceptibility of base materials and controls the aggregates’ ability to support vehicular load, especially during the spring-thaw period. To systematically evaluate the impact of fines content on the resilient properties of D-1 base course materials with varied fines content, gradation, moisture content and temperature during thawing and provide regression coefficients ki which are required for the flexible pavement design, a laboratory investigation was conducted on D-1 materials from Northern, Central, and Southeast Regions of Alaska Department of Transportation and Public Facilities (AKDOT&PF) at different temperatures, moisture and fines contents.
