THE DRYER DRUM PROCESS FOR PRODUCING BITUMINOUS CONCRETE MIXES

The turbulent mass process has recently been expended to include preparation of mixes using penetration grade asphalts. This report presents the results of data collected on the quality of mixtures being produced by this process in Iowa, Minnesota, and North Dakota. The evaluation effort was directed primarily toward obtaining answers to the following two questions: (1) Was the mixture being harmed by exposure to the direct flame in the dryer? (2) Would the equipment consistently produce a uniform product? Production costs are briefly discussed.
