Asphalt is the most cost-effective product to be placed not only in parking lots but highways, driveways, and roadways too. The cost to maintain asphalt is affordable and can save thousands over the years. Asphalt is 100% recyclable. When the existing asphalt pavement is milled or removed, the existing material can be recycled by being put back into the new asphalt pavement. This is called RAP, also known as reclaimed asphalt pavement.
