ACCURACY IN THE SAMPLING OF CHIPPINGS

IN MOST METHODS OF TESTING ROAD CONSTRUCTION MATERIALS THE ERRORS IN THE METHOD ITSELF AND THE FLUCTUATIONS BROUGHT ABOUT BY THE SAMPLING AND PROCESSING OF THE SAMPLE ARE UNKNOWN; THE AUTHOR HAS THEREFORE STARTED DETAILED INVESTIGATIONS WHICH ARE TO DETERMINE THE INFLUENCE OF THE DIVISION OF THE SAMPLE ON THE RESULT OF THE ANALYSIS OF THE PARTICLE SIZE DISTRIBUTION OF CHIPPINGS. AN EXAMPLE OF AN 8/12 CHIPPING IS USED TO SHOW HOW THE FLUCTUATIONS IN THE VALUES CAN BE DETERMINED, AND HOW A CORRECT EVALUATION OF THE MATERIAL BEING TESTED CAN BE MADE.
