USE OF COMPOST AS AN ASPHALT CONCRETE FILLER

EXPERIMENTATION WITH INCORPORATION OF COMPOSTED DOMESTIC REFUSE IN ASPHALTIC CONCRETES IS REPORTED. COMPOST WAS MANUFACTURED FROM DOMESTIC REFUSE BY A PROCESS WHICH INCLUDES MAGNETIC, BALLISTIC, AND HAND SEPARATION OF NONCOMPOSTABLES, THE GRIDING, COMPOSTING, DRYING AND FINAL GRINDING. COMPOSTING IS A FIVE-DAY AEROBIC REACTION AND TEMPERATURES RISE TO 170 F WITH AN EARTHY ODOR. THE EXPERIMENT UTILIZED ASPHALT AC2000 AND THE LIGONIER BLUE STONE CHIPS AND LIGONIER BLUE STONE SAND. RESULTS OF AGGREGATE SIEVE ANALYSES ARE TABULATED AS ARE ALSO EXPERIMENTAL MIXTURES AND MARSHALL TEST VALUES. THE EXPERIMENTAL PAVEMENT SHOWED NO DAMAGE OR DISINTEGRATION AFTER AN 8-DAY EXPOSURE TO AUTOMOBILE AND BUS LOADINGS AND TRAFFIC. A MARKET ANALYSIS OF THE POTENTIAL USE OF THIS 5 PERCENT COMPOST MIX IS REPORTED AND ESTIMATED COSTS OF PAVING MATERIALS FOR THE CONTROL AND COMPOST MIX ARE REPORTED. THE INCORPORATION OF COMPOSTED DOMESTIC REFUSE AS A FILLER MATERIAL IN ASPHALTIC COMCRETES CAN BE A SINK FOR MUNICIPAL REFUSE.
