MODIFICATION OF GRAIN COMPOSITION DURING COMPACTION OF BITUMINOUS MIXTURES /IN GERMAN/

STRENGTH TESTS ON DIABASE, PROPHYRY AND LIMESTONE CHIPPINGS, AND ALSO TESTS ON THE STRENGTH OF BINDERSTONE MIXTURES ARE CARRIED OUT USING SIMILAR AGGREGATES AND BITUMEN 200, IN ORDER TO DETERMINE THE BEHAVIOR OF SOFTER TYPES OF NATURAL ROCK IN DENSE MIXTURES. THE REFINEMENT OF THE GRAINS NOTICED DURING THE MANUFACURE OF MARSHALL SAMPLES WAS ESTABLISHED AS DEPENDENT ON INITIAL GRAIN COMPOSITION, ROCK STRENGTH, AND BINDER CONTENT. IT WAS ALSO SHOWN THAT THIS REFINEMENT OF GRAINS IN THE SELECTED AGGREGATE WAS AS EQUALLY MARKED DURING THE MANUFACTURE OF THE MARSHALL SAMPLE AS DURING COMPACTION ON THE ROAD. /FG/RRL/
