ABSTRACT
ABSTRACT: Many test methods have been developed over the years to test the water sensitivity of unbound materials. One of the recent methods is the Tube Suction test, which is used in this study to find the influence of grading on the water sensitivity of a material. This test utilizes the dielectric properties to measure the ability of the material to suck water. Cyclic load triaxial testing is used to study the effect of grading and moisture on the deformation properties of the material tested. By adding different amounts of water to samples with the same grading, the sensitivity to changes in degree of saturation is seen. The study shows that the deformation properties are affected by the level of saturation, especially for gradings with higher amounts of fines.
