Abstract

Moisture susceptibility in bitwninous mixture reduces the strength and durability of the bitwnen pavement due to the presence of water. Water disrupts the bond between aggregate and bitwnen. Because aggregate comprises 95% of bituminous mixtures, it has a major effect on the performance of mixture. Thus, the choice of right aggregate is important to reduce the presence of water. There are two points that have been identified in stripping: a failure of bonding of the binder to the aggregate (failure of adhesion) and a failure within the binder itself (failure of cohesion). The lab tests were conducted by employing four combinations of granite and limestone with two different aggregate gradations to fmd the effect between these two aggregates in the moisture susceptibility of bituminous mixtures. The result from Indirect Tensile Strength ratio and Retained Marshall shows that granite and gap graded have high potential to water susceptibility. The stripping of aggregate was not clearly show by visual inspection. It is appear that the failure may be derive from the adhesion or cohesion failure within the mixture.
