Why asphalt pavement should not be constructed in rainy and snowy weather?

During the construction of asphalt mixture surface, the factory temperature should be strictly controlled, and the construction temperature should be reduced in rainy days. When asphalt meets water, coarse and fine materials will not bond. There is also the problem of asphalt saturation: asphalt saturation is the asphalt volume divided by the mineral aggregate gap. If there is water, it can fill some gaps and reduce asphalt saturation, which will affect the quality after compaction.
