Rainwater immersion can affect the performance of the pavement layer (laston). Falling and stagnant rainwater can cause changes in the physical and mechanical properties of laston materials, such as decreased stability, strength, and resistance to deformation. This affects the long-term performance of the pavement layer. The purpose of the study was to analyze the ability of asphalt concrete to withstand the influence of rainwater bathing. By knowing this, it can estimate the ability of asphalt concrete to withstand loads and pressures, as well as resistance to environmental influences, including rainwater, and analyze the difference in laston performance when soaked in rainwater for 24 hours and 48 hours. A trial and error method that involves experimenting with multiple samples to collect data is used. From the results of research that rainwater immersion can cause a decrease in the strength and stiffness of the asphalt mixture and the potential for cracking due to volume changes due to water absorption. The performance of laston soaked in rainwater for 24 hours and 48 hours, resulting in a decrease in stability, which was obtained 98.13% in 24 hours and 49.40% in 48 hours. The length of soaking time will affect the stability value or strength value.
