COMPARATIVE COMPACTION OF BITUMINOUS SURFACES WITH RUBBER-TYRED ROLLERS, VIBRATORY ROLLERS AND STATIC ROLLERS /IN GERMAN/

DESIGN ENGINEERS OF SCHEID MASCHINENFABRIK G.M.B.H., LIMBURG, REPORT ON EXPERIENCES AND KNOWLEDGE GATHERED FROM TRIALS WITH A THREE-WHEEL ROLLER, A TANDEM VIBRATION ROLLER AND A RUBBER-TIRED ROLLER ON BUILDING SITES. IT WAS SHOWN THAT THE RUBBER-TIRED ROLLER AND THE VIBRATION ROLLER CAN BE REGARDED AS EQUALLY EFFECTIVE FOR THE COMPACTION OF COARSE BINDERS. THE COMPACTION OF AN 11-13 CM THICK BITUMINOUS BASECOURSE USING A RUBBER-TIRED ROLLER WAS MORE SUCCESSFUL (LOWER POROSITY, BEST SURFACE FINISH). THE COMPACTION OBTAINED WITH THE STATIC ROLLER WAS NOT AS GOOD AS THAT OBTAINED WITH THE OTHER TWO MACHINES. THE DISADVANTAGE OF VIBRATION ROLLERS IS THAT THE VIBRATOR HAS TO BE SWITCHED OFF EVERY TIME WHEN REVERSING. AS REGARDS RETENTION OF COMPACTION TEMPERATURE, WHEEL LOAD, AND INTERNAL WHEEL PRESSURE, THE RUBBER-TIRED ROLLER SHOULD BE GIVEN PREFERENCE TO THE VIBRATION ROLLER AND IN PARTICULAR TO THE THREE-WHEEL ROLLER. THE OUTPUT OF THE RUBBER-TIRED ROLLER WAS HIGHER AT ALMOST EQUAL OPERATING COSTS PER HOUR. /FG/RRL/
