THE DESIGN OF BRICK SURFACES TO OBVIATE SLIPPERINESS

TWO DEVELOPMENTS IN RECENT YEARS HAVE A DIRECT BEARING ON THE ANTI-SKID PROPERTIES OF BRICK PAVEMENT SURFACES: (1) THE SURFACE REMOVAL METHOD OF BITUMINOUS FILLER APPLICATIONS. (2) THE VERTICAL FIBER LUG TYPE OF PAVING BRICK. TESTS INDICATED A HIGH COEFFICIENT OF FRICTION ON VERTICAL FIBE BRICK SURFACES PROVIDED THE SURFACE WA FREE OF ASPHALT FILLER. THE SURFACE REMOVAL METHOD USING WHITEWASH AS THE ADHESION PREVENTIVE WAS USED AT JACKSONVILLE, FLORIDA, IN 1929 AND IN WILMINGTON, DELAWARE IN 1931. A NON-DRYING MOIST FILM WAS FIRST USED IN OHIO. A CALCIUM CHLORIDE SOLUTION HAS BEEN FOUND TO BE THE BEST MEDIUM YET DEVISED FOR THIS PURPOSE. THE SURFACE REMOVAL METHOD PERMITS ADVANTAGEOUS DIRECT POURING OF ASPAHLT IN JOINTS, AND BECAUSE OF COMPENSATING FACTORS THERE IS NO INCREASE IN COST BECAUSE OF ITS USE. VERTICAL FIBER LUG BRICK ARE NOW AVAILABLE AND ARE RECOMMENDED BECAUSE THE WIRE CUT SURFACE IS DESIRABLE FROM AN ANTI-SKID AND LUGS FROM AN ENGINEERING STANDPOINT. /AUTHOR/
