1 - Asphalt Milling. Asphalt milling is easy to confuse with pulverizing, since both fundamentally involve pulling up and crushing existing pavement. Milling, however, is a recycling and re-paving procedure, aimed at removing the top layer of asphalt from a street, parking lot or driveway without disturbing the sub-base.
