    Reasons Behind Heaving Asphalt Asphalt Advisor

    Reasons Behind Heaving Asphalt. Frost heave is a common problem in colder climates. Many people are watching their asphalt heave as the winter temperatures fluctuate. The cause is the freezing and thawing that comes with above and below freezing temperatures that start the formation of lenses. Ice lenses form in the soil under the asphalt
