Asphalt concrete, being a pivotal material in road construction, has its water stability intricately tied to the road's service life and safety. In engineering practice, an ASA is commonly employed to enhance the water stability of asphalt concrete. This investigation aims to scrutinize the impact of various ASAs on the water stability of asphalt concrete by selecting three frequently used ones. The investigation is conducted through the Marshall water immersion test. Experimental outcomes indicate that cement, AASA, and NASA effectively bolster the water stability of asphalt concrete, with NASA demonstrating the most superior performance.
