- This study investigates the effect of a 0.3% amine-free anti-stripping agent on hot mix asphalt to improve moisture resistance. The modified mixtures showed lower moisture content, higher tensile strength, better Marshall stability, and improved durability compared with the unmodified mixtures. The findings confirm that the additive effectively enhances the performance and durability of asphalt pavements, particularly under moisture exposure
