EXPERIMENTAL FLY ASH CONCRETE PAVEMENT IN MICHIGAN
AN EXPERIMENTAL CONCRETE ROAD, 1750 FT LONG, WAS CONSTRUCTED IN 1955 ON A LEVEL SITE CARRING HEAVILY LOADED VEHICLES AT NOT VERY HIGH SPEEDS. REINFORCED CONCRETE OF 8-IN THICKNESS HAD TRANSVERSE JOINTS WITH 1-IN DIAMETER STEEL DOWELS ON 12-IN CENTRES AND SEALED WITH RUBBER-BITUMEN IN FIVE EXPERIMENTAL SECTIONS FLY-ASH RANGED FROM 0 TO 200 1B AND THE CEMENT FROM 5.5 TO 4.0 SACKS PER CUBIC YARD OF CONCRETE. THE FLY-ASH HAD A 13 TO 14 PER CENT IGNITION LOSS. FINE AGGREGATE WAS A SATISFACTORY LOCAL S AND, COARSE AGGREGATE WAS A DURABLE CRUSHED DOLOMITE AND A NEUTRALISED VINSOL RESIN IN SOLUTION WAS THE AIR-ENTRAINING AGENT. CONSTRUCTION DIFFICULTIES ARE MENTIONED, LABORATORY TEST RESULTS AND OBSERVATIONS ON SERVICE PERFORMANCE ARE GIVEN. AFTER EIGHT YEARS THERE WAS NO INDICATION THAT THE FLY-ASH HAD ANY DELETERIOUS OR BENEFICIAL EFFECT ON PERFORMANCE, NOR DID THE HIGH PROPORTION OF AIR-ENTRAINING AGENT APPEAR TO HAVE ANY EFFECT. /RRL/
