TESTING THE WATER SENSITIVITY OF STONE DUST FILLERS (IN GERMAN)

THE WATER SENSITIVITY OF STONE DUSTS IS ALMOST EXCLUSIVELY CAUSED BY THE PRESENCE OF ERODED PRODUCTS; THEIR SUITABILITY AS FILLERS IS THEREFORE ONLY IMPAIRED IF THE PROPORTION OF WEATHERED MATERIAL IS TOO HIGH. SPECIAL TEST METHODS FOR EVALUATING THE WATER SENSITIVITY OF FILLERS AND OF SANDS ARE PRESENTED. BITUMINOUS PAVEMENTS CAN BE SENSITIVE TO THE ACTION OF WATER IF CERTAIN SANDS AND FILLERS ARE USED, AND BECAUSE OF THIS MAY SUFFER CONSIDERABLE DAMAGE IN THE FORM OF LOOSENING OF THE PARTICLES BECAUSE OF THE WEARING AND STRIPPING OF THE MORTAR WHEREAS PREVIOUS METHOS OF TESTING FILLERS WERE ONLY CONCERNED WITH THE CONCENTRATION OF VOLUME OF FILLERS AND ITS INFLUENCE ON BINDER STIFFNESS AND BINDER REQUIREMENTS, THE TECHNISCHE HOCHSCULE MUNICH HAS UNDERTAKEN TESTS ON SAND ASPHALTS BY MEANS OF WHICH, AS HAPPENS IN PRACTICE, THE BEHAVIOR OF MIXTURES OF FILLER, SAND AND BINDER UNDER THE ACTION OF WATER WAS ASCERTAINED. /FG/RRL/
