Popis: Moisture damage occur due to loss of bond between bitumen and aggregates. Ingression of water in bituminous mixes leads to various damage. The objective of this study is to investigate extent of performance of Nano particle based anti-stripping agent (Wet Bound-S) in resisting the moisture damage and improving the durability of bituminous mix. Bituminous mixes were prepared with polymer modified binder (PMB-40); optimum binder content was found using Marshall testing procedure. To check the resistance toward moisture, specimen was prepared at three void ratios of 3%, 5% and 7%, each sample set was tested in dry condition and moist condition by injecting moisture at 30 psi and 40 psi. Then each of these sample set were subjected to indirect tensile strength ratio test and dynamic creep test. Use of anti-stripping agent was done to see its effect under adverse condition. From the outcome of this study, it was observed that PMB-40 with additive exhibit more resistance to moisture.
