    Driveways - Asphalt Pavement

    Full-depth asphalt driveways are built entirely of asphalt paving mixture — from the soil subgrade up. Full-depth driveways keep water out of the pavement, so water never enters the pavement to swell when it freezes. Full-depth asphalt provides a better balance of strength and flexibility — plus durability — than any other material.
