On very large projects, six or eight rollers may be needed. A lot of projects are compacted with three rollers: a breakdown roller, a compaction roller, and a finish roller. On most average projects, two rollers are used – a vibratory steel-wheeled roller for breakdown and compaction, and a heavy static steel wheel for finish rolling.
Jun 26, 2017· 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.
