EVALUATION OF ASPHALT CONCRETE PRODUCED BY THE DRYER-DRUM MIXING PROCESS

The quality of asphalt concrete produced by a dryer-drum mixing plant was investigated. A dryer-drum mixing plant was used on two state projects in northern California during 1973. The A.C. mixture did not appear to be harmed by the simultaneous drying of the aggregate and mixing of the aggregate and asphalt. However, indications exist that unconsumed burner fuel may have contaminated the asphalt and softened it. This dryer-drum mixing equipment produced an A.C. mixture of a uniformity that matches the mean capability of conventional plants. Both the asphalt content and the aggregate gradation remained within reasonable limits of the sought values.
