PAVEMENT GROOVING AND EXPERIENCE ON WASHINGTON STATE HIGHWAY

PAVEMENT GROOVING (1) INCREASES THE SKID RESISTANCE QUALITY OF THE PAVEMENT BY PROVIDING A HIGHER COEFFICIENT OF FRICTION AND BY RESISTING LATERAL VEHICLE MOVEMENT THROUGH THE INTERLOCKING OFFERED BETWEEN THE PAVEMENT GROOVES AND TIRES, AND (2) PROVIDES AN ADDITIONAL ESCAPE ROUTE FOR EXCESS WATER ON THE PAVEMENT AND AN AUDIBLE WARNING TO THE DRIVER WHEN ENTERING A CURVE. THE USE OF PAVEMENT GROOVING IS EFFECTIVE ON WORN OR SMOOTH CONCRETE PAVEMENT WHERE CURVATURE AND WET PAVEMENT CONTRIBUTE TO A LARGE NUMBER OF ACCIDENTS. /AUTHOR/
