EFFECT OF THE COMPOSITION AND SURFACE TEXTURE ON SKID-RESISTANCE AND WEAR /IN GERMAN/

CURRENT INVESTIGATIONS INTO THE EFFECT OF CONCRETE MIX-DESIGN AND SURFACE TEXTURE ON THE WEARING AND SKIDDING RESISTANCE OF CONCRETE PAVEMENTS ARE DESCRIBED. LABORATORY TEST RESULTS SHOWED THE FINELY GROOVED CONCRETE SURFACES (SPACEING OF GROOVES: 2,5 MM) HAVE A HIGHER COEFFICIENT OF FRICTION THAN SMOOTH SURFACES OR SURFACES WITH COARSE GROOVES. THE INFLUENCE OF THE GRADING AND MINERALOGICAL CHARACTERISTICS OF AGGREGATES ON SKIDDING RESISTANCE HAS NOT BEEN DEFINED YET BUT, DURING LABORATORY WEARING TESTS, THE SKIDDING RESISTANCE WAS CONSIDERABLY INCREASED BY THE ADDITION OF HARD AGGREGATES IN THE SURFACING COURSE. FURTHER DATA WILL BE OBTAINED FROM TEST CYLINDERS PLACED IN THE SURFACING OF HEAVILY-TRAFFICKED CONCRETE ROADS. ATTENTION IS DRAWN TO THE NEED FOR SELECTING ECONOMICAL AND PRACTICAL METHODS OF IMPROVING WEARING AND SKIDDING RESISTANCE OF CONCRETE PAVEMENTS. /LCPC(A) /RRL/
