What does a Mixing Roll Operator do?
Controls mixing machine to blend asphalt paste of two or more colors to form marbleized asphalt tile: Starts machine and turns valves to heat rollers to specified temperature, or until surface of rollers feels hot enough to melt and mix asphalt. Shovels or feeds asphalt paste of prescribed colors between rollers until mixing appears complete. Signals other workers to cut off and catch marbleized material emerging from machine, and directs helpers who assist in mixing, rolling, and cutting product.
