AN INVESTIGATION INTO THE METHODS OF SELECTING SHALES FOR PAVEMENT CONSTRUCTION

THE EXPERIMENTAL WORK COMPLETED IS SUMMARIZED IN A PROJECT INVESTIGATING THE BEHAVIOR OF 'LOW GRADE AGGREGATES', I.E. PRINCIPALLY SHALES, ON BEHALF OF THE DEPARTMENT OF MAIN ROADS IN NEW SOUTH WALES. SAMPLES WERE TAKEN FROM 50 SHALE DEPOSITS AS WELL AS FROM SECTIONS OF PAVEMENT IN WHICH THE MATERIALS WERE IN USE. THE SHALES WERE SUBJECTED TO DETAILED EXAMINATIONS, WHEREIN CORRELATIONS WERE SOUGHT BETWEEN THE MINERALOGICAL COMPOSITIONS, RESISTANCES TO CHEMICAL AND PHYSICAL WEATHERING AND MECHANICAL BREAKDOWN, AND PERFORMANCES OF THE PAVEMENTS. THE RESULTS WERE USED TO DEVELOP A LABORATORY TESTING PROCEDURE FOR DISTINGUISHING SOUND VARIETIES OF SHALE. STABILIZATION WITH CEMENT WAS SUGGESTED FOR CORRECTING HIGH PLASTICITY RESULTING FROM THE INCORPORATION IN THE PAVEMENTS OF SOIL AND WEATHERING MATERIALS FROM THE QUARRIES. /AUTHOR/RRL/
