A plant will produce 440 tph for a project. The mat will be 12 ft wide, 1 in. thick, and will have a density of 112 lb/sy-in. A vibratory roller with a 60-in.-wide drum will be used for compaction. Assume a 50-min hour efficiency factor for the roller. The overlap between adjacent laps and overedges will be 6-in. minimum. It is estimated that nonproductive travel will add 15% to total travel.

From a test mat, it was found that three passes with the roller are required to achieve density. To account for acceleration and deceleration when changing directions, add 10% to the average roller speed to calculate a running speed. What is the required roller speed if only one roller is available?
