DISCARDED BATTERY CASES AS SYNTHETIC AGGREGATE IN ASPHALTIC CONCRETE

PRESENTLY, MORE THAN 50,000,000 USED STORAGE BATTERY CASES ARE THROWN AWAY EACH YEAR. A ROUGH CALCULATION INDICATES THAT WHEN CRUSHED, THESE CASES WILL YIELD ABOUT 115,000 CUBIC YARDS OF MATERIAL. IF THIS MATERIAL COULD BE SUCCESSFULLY INCORPORATED AS AGGREGATE IN HOT-MIX ASPHALTIC CONCRETE, IT WOULD BE IDEALLY SUITED FOR USE ON SMALL PAVING JOBS SUCH AS DRIVEWAYS, PARKING LOTS AND CITY STREETS. LABORATORY EXPERIMENTS WITH THE STORAGE BATTERY CASES, WHICH IN GENERAL ARE MADE OF RUBBER, PLASTICS, AND ASPHALT WITH VARIOUS TYPES OF FILLERS AND FIBERS, PROVIDED A NUMBER OF FINDINGS. IN COMBINATION WITH OTHER AGGREGATES, ACCORDING TO THE MARSHALL METHOD OF MIX DESIGN, THE CRUSHED BATTERY CASE AGGREGATE IS SUITABLE FOR ASPHALTIC CONCRETE, ALTHOUGH THE BATTERY CASE CRUSHINGS ALONE ARE NOT SUITABLE. THEY HAVE THE DESIRABLE CHARACTERISTICS OF BEING STRONG, LIGHTWEIGHT, ANGULAR, AND RESISTANT TO ABRASION; THEIR UNDESIRABLE CHARACTERISTICS INCLUDE FLAMMABILITY, LARGE PERCENTAGE OF SMOOTH-SIDED PARTICLES, AND A TENDENCY TO PRODUCE MIXES WITH HIGH FLOW VALUES. /AUTHOR/
