Abstract

Moisture damage or stripping is one the fundamental defects of asphaltic surface layers. MOISTURE DAMAGE has great effect on other defect types of asphalt surface layers. Generally, MOISTURE DAMAGE is loss of adhesion between asphalt binder and aggregates or loss of cohesion in asphaltbinder structure. Since hot mix asphalt is made of different components, performance improvement of each component will result better resistance against MOISTURE DAMAGE effects. However, weight of asphalt binder as one of the components of hot ASPHALT CONCRETE is not high, but hasmajor effect on the better performance, durability and stability of ASPHALT CONCRETE mixtures and any change in asphalt binder performance has remarkable effects on the ASPHALT CONCRETE performance. Nowadays, modifiers are used for modifying asphalt binders and upgrading its performance. NANOparticles include NANO-clay are one of the modifier types that are used for modifying asphalt binders. Because of layered structure, NANO-clay would enhance performance properties of NANO composites. In this research, two types of NANO-clay is used for evaluating their effects on the MOISTURE DAMAGE resistance of ASPHALT CONCRETEs (montmorillonite CA and CB). Marshall Test, BOILING TEXAS TEST and image processing are used for un-compacted samples as well as MOISTURE DAMAGE test (AASHTO T283) and RESILIENT MODULUS TEST are used for compacted samples containing 0, 2, 4 and 6 percent of each NANO-clay modifier. Results show that ASPHALT CONCRETE has better resistance to MOISTURE DAMAGE by adding NANO-clay modifiers.
