Effects of Aging and Moisture Damage on Asphaltic Mixture

Moisture damage in asphalt mixtures refers to the loss of strength and durability due presence water. Road network is showing severe deterioration such as raveling stripping because bond between aggregates film broken water intrusion. To minimize moisture mixes are investigated evaluate effect air voids degree saturation media attack conditioning period. one major issues distress. It adhesive cohesive failure mixture it will shorten pavement life. Moisture-sensitive need be identified during course design process which fulfil specified minimum standard. The laboratory testing procedures currently available for compacted Hot Mix Asphalt (HMA) test sensitivity were primarily developed determine resistance by a particular combination aggregate. These tests measuring relative change single parameter before after (i.e. Tensile Strength Ratio Resilient Modulus Ratio).
