CRUSHING RESISTANCE OF SURFACE-TREATMENT AGGREGATES

THE CRUSHING OF AGGREGATE BY ROAD ROLLERS IN COMPACTING SURFACE-TREATMENT AGGREGATE WAS STUDIED. THE RESISTANCE OF THE AGGREGATE TO CRUSHING VARIED WITH THE TYPE AND SOURCE OF THE AGGREGATE. THE RATE OF DEGRADATION WAS MORE RAPID WITH OPEN THAN WITH DENSE GRADATIONS. AS THE WEIGHT OF THE ROLLER WAS INCREASED, THE DEGRADATION INCREASED ALTHOUGH NOT PROPORTIONALLY. ALSO MORE BREAKAGE OCCURRED /APPROXIMATELY TWICE THE AMOUNT/ WHEN THE ROLLING WAS DONE ON A RIGID BASE INSTEAD OF ON A FLEXIBLE BASE. /AUTHOR/
