SINTERED COAL REFUSE LIGHTWEIGHT AGGREGATE FOR HIGH-FRICTION BITUMINOUS SURFACE COURSES

Synthetic lightweight aggregate was successfully produced from bituminous coal refuse using an improved sintering grate process. The improved process incorporates a sealed sintering facility with a multipass recycled draft and is particularly applicable to processing bituminous coal refuse since it alleviates some salient air-pollution problems and provides an environmentally acceptable process. A means is provided for utilizing a waste product. A thorough laboratory evaluation of the aggregate and bituminous concrete mixes incorporating the sintered aggregate indicated a satisfactory aggregate for lightweight bituminous mixes was produced.
