註釋Tests reported herein were conducted to determine skid resistance of T17 membrane surfacing and performance of nonskid materials applied to the surfacing. Tests were conducted on the nonskid-treated membrane to determine if it could be accordion-folded without removing the nonskid compound. Three compounds tested (Ferrox, 201 Fuller, and 301 Fuller) consisted of liquid binders and abrasive particles. Three other products tested (Safety Walk, Scotch Tred, and Slip-X Safety Tread) consisted of abrasive-treated flexible materials with pressure-sensitive adhesive backings. These materials were bonded to the membrane surfacing by placing the backings in contact with membrane and applying pressure. After the materials had been applied, they were tested by towing a locked-wheel cart across the treated surfacing. Laboratory tests were conducted on untreated and treated membrane to determine coefficients of friction and obtain a correlation between laboratory and load-cart methods of determining these coefficients.
