From page 165...
... is a thin surfacing material composed of polymer-modified asphalt cement and fine-graded aggregate mixed in a conventional HMA plant and placed using a conventional asphalt paving machine. It is primarily used in Ohio as a PM treatment capable of retarding raveling and oxidation, reducing the intrusion of water, improving surface friction, and removing minor surface irregularities.

... that hurls steel abrasive materials at the road surface to increase the texture of concrete surfaces. This method has been used on many highprofile concrete road texture restoration projects in the United States, including the shuttle runway for NASA, major airport runways, tunnels, Interstates, and the Lake Pontchartrain Bridge in Louisiana.
