STUDY OF FILLERS IN SAND-BITUMINOUS MIXES

AN EXTRACT FROM A RESEARCH BULLETIN PREPARED AT THE CENTRAL ROAD RESEARCH INSTITUTE, INDIA, FOR THE INDIAN ROADS CONGRESS, IS PRESENTED. SUITABLE HOT SAND-BITUMINOUS MIXTURES CAN BE DESIGNED USING ALMOST ANY LOCAL SAND BY ITSELF, OR BY BLENDING SANDS FROM DIFFERENT SOURCES, OR BY ADDING MINERAL FILLER IN SMALL QUANTITIES. CEMENT, BRICK DUST, KANDAR DUST, LIMESTONE DUST AND SILT CAN BE USED AS FILLER IN SAND-MIXES, WHICH PROVIDE A SUITABLE SUBSTITUTE FOR SURFACE DRESSING OR OPEN GRADED PRE-MIX CARPET. RESULTS OBTAINED WITH CEMENT, BRICK DUST AND SILT WERE COMPARED. THE PROPERTIES OF THE FILLERS AND THE COMBINATIONS OF THE MIXES ARE LISTED. THE MIXES PRODUCED SUITABLY STABLE SURFACE COURSES WHEN LAID THINLY ON AN UNYIELDING BASE, BUT ARE LIABLE TO DEFORM UNDER HEAVY TRAFFIC IF LAID TOO THICKLY. THESE MIXES SHOULD NOT BE USED ON A BASE OF POOR PROFILE WITHOUT FIRST LAYING A BASE COURSE OR A LEVELLING COURSE. /RRL/
