AGGREGATE MEASURING DEVICE FROM SOUTH AFRICA

THE AGGREGATE MEASURING DEVICE IS AN INSTRUMENT BY WHICH THE AVERAGE SIZE OF THE CHIPPINGS TO BE USED IN A ROAD SURFACING TREATMENT CAN BE MEASURED. THIS AVERAGE LEAST DIMENSION (ALD) DETERMINES THE QUANTITY OF STONE AND BINDER NECESSARY FOR A SUCCESSFUL ROAD TREATMENT. AN APPARATUS WAS DEVELOPED EMPLOYING A HYDRAULIC CIRCUIT TO MEASURE RAPIDLY THE ALD OF CHIPPINGS ACCURATELY. THE APPARATUS CONSISTS OF AN OIL RESERVOIR, A MASTER CYLINDER AND A SLAVE CYLINDER INTIMATELY CONNECTED TO TWO HARDENED STEEL ANVILS AND AN INDICATOR DIAL. MEASUREMENT IS ACHIEVED BY PLACING INDIVIDUAL CHIPPINGS BETWEEN THE ANVILS OF THE INSTRUMENT AND DEPRESSING A PLUNGER LEVER.
