REQUIREMENTS OF BITUMINOUS MIXTURES FOR FARM ROAD CONSTRUCTION /IN GERMAN/

MENTION IS MADE OF THE SENSITIVITY OF FARM ROADS TO DIRT, WHICH LEADS TO THESE ROADS BEING PARTICULARLY EXPOSED TO DAMAGE IF THEY ARE INSUFFICIENTLY COMPACTED. IN EXTREME CASES THE VOIDS CONTENT AMOUNTED TO 20 PERCENT VOLUME. HERE THE BUILD-UP OF THE GRAIN SIZE IN THE MINERAL MIXTURE PLAYS A SIGNIFICANT PART, AS DOES THE PROPORTIONING OF THE BITUMEN. BUT ALSO THE WEATHER IN WINTER FOR EXAMPLE CAUSES LACK OF COMPACTION. THE AUTHOR INTRODUCES METHODS OF ALTERING THE MIXTURE CONDITION, TO IMPROVE COMPACTION. THE MOST IMPORTANT OF THESE IS THE INCREASE OF THE BITUMEN CONTENT. /FG/RRL/
