What can excessive moisture during the curing process lead to in asphalt?

Excessive moisture during the curing process of asphalt can lead to potential cracking. This occurs because moisture can interfere with the proper adhesion of asphalt components as they cure. When asphalt binds, it relies on a controlled environment to achieve the right consistency and strength. If too much moisture is present, it can weaken the bond between the aggregates and the asphalt binder, resulting in a compromised structure. As the asphalt dries and hardens, the internal stresses caused by the trapped moisture can lead to cracks forming in the surface, which ultimately affects the longevity and performance of the asphalt pavement.

Enhanced durability and increased flexibility are characteristics typically associated with well-cured asphalt under optimal moisture conditions, not those overwhelmed by excessive moisture. Regarding decreased weight, moisture does not reduce the weight of asphalt but can create issues with stability and overall performance due to the effects mentioned.
