Profile: Global Paving LLC offers asphalt paving for driveways and parking lots, to seal coating for curbs and roadways. Asphalt is made up of stones, sand and liquid tar. With liquid tar it will take time to cure. Asphalt may look smoother throughout different areas of your driveway. This is because of the different size stones throughout the asphalt mixture. Also, some area in the asphalt that have been done by hand tools, may appear different that the asphalt that was laid by machinery.
