This recent project details the process by which a commercial asphalt parking lot is milled and paved and then has ADA Compliant line striping applied to the new surface. The entire life of a pavement is affected by the quality of the materials upon which it is built. When implementing parking lot asphalt replacement and/or maintenance there are many aspects to consider, each with specific criteria and specifications that must be met.
Step 1: Asphalt Milling | Removing the Asphalt
Pavement milling (cold planing, asphalt milling, or profiling) is the process of removing at least part of the surface of a paved area such a road, bridge or parking lot. Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal. The process of asphalt milling is one of the most common forms of asphalt reconstruction.
Asphalt milling is completed in a few steps. First the milling machine scrapes off the top layer of asphalt using a milling drum that is set to the desired depth, usually 2″. The asphalt that is scraped off is transferred through the machine to a long conveyor belt that deposits the milled asphalt into dump trucks driving at the end of the conveyor. The dump truck then takes the “millings” back to the asphalt plant where they are recycled and used to create new asphalt. The milled surface that is left behind is then swept clean of any loose debris and is now ready for new asphalt.
