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.
