Aug 30, 2019  Abstract. Moisture in asphalt concrete (AC) pavements does not only cause distresses like potholes, ravelling, etc. but also exacerbates distresses like fatigue and rutting. Moisture susceptibility of AC mixtures is usually characterized using the Modified Lottman Test (AASHTO T283) adopted in Superpave mix design.
