THE MEASUREMENT OF VOIDS IN BITUMINOUS MIXTURES BY PRESSURE METHODS

VOIDS IN BITUMINOUS PAVING MIXES ARE AN IMPORTANT FACTOR IN PERFORMANCE AND ARE USUALLY CONSIDERED IN DESIGN. IF A MIX LACKS VOIDS, TRAFFIC COMPACTION MAY FORCE THE ASPHALT TO THE PAVEMENT SURFACE, RESULTING IN SLIPPERINESS AND INSTABILITY. ON THE OTHER HAND, TOO HIGH A VOID CONTENT MAY PERMIT THE EASY ACCESS OF WATER AND AIR, CAUSING PREMATURE DETERIORATION OF THE PAVEMENT. THE FACTORS WHICH CONTROL THE VOID CONTENT ARE THE DEGREE OF COMPACTION, THE ASPHALT CONTENT, AND THE GRADUATION AND VOLUME OF AGGREGATES. A METHOD IS DESCRIBED FOR THE DIRECT MEASUREMENT OF VOID CONTENT BY MEANS OF PRESSURE.
