PRELIMINARY STUDY OF THE TRANSVERSE ADHESION OF PAVEMENTS /IN FRENCH/

MEASUREMENTS WERE CARRIED OUT WITH THE STRADOGRAPH AT SPEEDS UP TO 120 KM/H, THE ANGLES OF DRIFT BEING BETWEEN 2 AND 12 DEGREES. RESULTS ARE GIVEN AND EMPHASIS LAID ON THE INFLUENCE OF SPEED ON THE COEFFICIENT OF TRANSVERSE FRICTION, THE INFLUENCE OF THE TYPE OF TIRE (SMOOTH OR PATTERNED), AND THE INFLUENCE OF THE ANGLE OF DRIFT. AFTER OBSERVATIONS ON A LARGE NUMBER OF SURFACINGS, IT WAS FOUND THAT THERE EXISTS A SIMILARITY BETWEEN TRANSVERSE AND LONGITUDINAL ADHESION AT HIGH SPEED, AND THAT THE GEOMETRIC ROUGHNESS OF THE SURFACING PLAYS AN IMPORTANT ROLE. IT IS SUGGESTED THAT FURTHER INVESTIGATIONS BE CARRIED OUT TO DETERMINE THE OPTIMUM ANGLE OF DRIFT FOR ROUTINE TESTS. /LCPC(A)/RRL/
