WEATHERING STUDY OF SOME AGGREGATES

A NUMBER OF SURFACE TREATMENTS HAD FAILED BECAUSE OF DISINTEGRATION OF POOR AGGREGATE USED AS THE COVER STONE. AN INVESTIGATION WAS MADE TO DETERMINE MEANS TO TEST AGGREGATE THAT WOULD IDENTIFY THESE POOR AGGREGATE. IT WAS LEARNED THAT BY WET GRINDING THE AGGREGATE TO FINE SIZE, THE POOR AGGREGATE HAD HIGHER LOSS IN WEIGHT AND ALSO THE SOILS, PRODUCED BY THE GRINDING, HAD HIGHEST LIQUID LIMITS. /AUTHOR/
