“Whenever it rains and the rainwater accumulates on the road, tires from the road actually squeeze the water into the pavement,” Caltrans spokesman Bob Haus says. “So that repeated squeezing into the asphalt and into the concrete causes the cracking.” Water gets through those cracks and weakens the soil under the road.

What does rain do to roads?

Rain actually causes your tires to lose traction—when the road gets wet, the water mixes with the dirt on the asphalt, making it harder for your tires to “hang on” to the road. Simply put, rain makes everything slippery, and puddles that form can lead to hydroplaning.
