COLLECTION OF EXPERIENCE ON THE QUALITY OF ROAD SURFACES WHICH CAN BE ATTAINED

ERFAHRUNGSSAMMLUNG UEBER DIE ERREICHBARE QUALITAET VON STRASSENOBERFLAECHEN

THE AIM IS TO COLLECT DATA ON THE QUALITY OF ROAD SURFACINGS WHICH CAN ACTUALLY BE OBTAINED WITH REFERENCE TO SURFACE CHARACTERISTICS. THE COLLECTION WILL REFER TO SECTIONS MADE WITH ASPHALTIC CONCRETE, GUSSASPHALT AND CEMENT CONCRETE. ON RECONSTRUCTED, EXTENDED AND NEWLY BUILT SECTIONS OF ROAD, THE ROAD SURFACE IS TO BE EXAMINED BEFORE BEING GIVEN OVER TO TRAFFIC FOR EVENNESS IN THE LONGITUDINAL AND CROSSWISE DIRECTION AND FOR SKIDDING RESISTANCE. FOR THIS THE PLANOGRAPH, STRAIGHTENING LATH AND SLOPEMETER, STUTTGART FRICTION METER, SRT EQUIPMENT AND DISCHARGE METER ARE TO BE USED. THE MEASUREMENTS ARE TO BE REPEATED AFTER THE ROADS HAVE BEEN TRAFFICKED. THE COLLECTED DATA WILL BE EVALUATED BY COMPUTER.
