Does Your Drainage Cause Asphalt Driveway

Winter Weather's Effect on Asphalt Pavement

Asphalt pavement that has existing problems within the surface and sub-base will show the effects of winter asphalt damage first. Freezing temperatures cause the water that has seeped below the pavement’s surface to freeze and expand. Which then causes the surface to buckle, shift, and lift upwards, which is also known as “frost heave.”

Reasons Behind Heaving Asphalt Asphalt Advisor

Frost heave will take care of itself in many situations, once the temperatures raise. The best course of action is to wait until spring and see if the asphalt settles back to the correct grade. If the asphalt is still high, the severity will dictate whether it should be lowered by infrared repair or sawcut repair.
