A TECHNIQUE FOR THE DETERMINATION OF A THERMAL CHARACTERISTIC OF STONE

A TECHNIQUE IS DEVELOPED FOR THE DIRECT DETERMINATION OF THE THERMAL DIFFUSIVITY OF ROCKS. THE PARTICULAR APPLICATION HAS BEEN TO CRUSHED STONE COARSE AGGREGATES USED IN INDIANA CONCRETE PAVEMENT CONSTRUCTION. VALUES OF THERMAL DIFFUSIVITY ARE GIVEN FOR TWO AGGREGATES WITH GOOD FIELD PERFORMANCE AND FOR TWO WITH POOR FIELD PERFORMANCE WHEN USED IN CONCRETE PAVEMENTS. VALUES FOR BOTH WET AND DRY STONE ARE PRESENTED. INCREASES IN THE VALUE OF THERMAL DIFFUSIVITY OF 20 TO 60 PERCENT WERE FOUND FOR LESS THAN FIVE PERCENT SATURATION OF THE VOIDS OF THE STONE. /AUTHOR/
