One test strip shall be made on areas which are of the full operating width of the equipment to be used for the work and a minimum length of 50 feet. The test strip shall be made on Portland cement concrete pavement. The actual length of the test strips shall be sufficient to determine the vehicle speed, water pressure, height of spray nozzle above the pavement, angle of spray and incidence with the pavement, and quantity of abrasive to be used (if any) to satisfactorily remove paint and/or rubber deposits from the pavement surfaces without damage to the pavement surface. The determination of satisfactory removal shall be in accordance with paragraph 15.8 COMPLIANCE TESTING. The Contractor shall not proceed with the work until the results of the test section are satisfactory to the Contracting Officer.

6.8 COMPLIANCE TESTING: The determination of compliance with 85 or 100 percent paint and/or rubber removal shall be determined by direct testing within the test strip areas.

6.8.1 Testing shall be performed by placing a one foot square transparent material with an inscribed 100 square (minimum) grid pattern on the pavement surface at random locations and counting the number of squares containing paint and/or rubber build-up/deposits. Compliance with 85% removal shall be considered obtained when the number of counted squares does not exceed 15 percent of the total number of squares on the grid.

6.8.2 Squares containing paint and/or rubber build-up/deposits are squares on the pavement surface where build-up/deposits of paint and/or rubber can be removed by scratching the deposit with a flat sharp object (i.e., pocket knife) without damage to the pavement surface. Paint and/or rubber stain is material in the pavement surface microtexture that cannot be removed without damage to the pavement surface. Stain is generally embedded in the surface of the pavement below the horizontal plane of the surface texture. The Contractor is not responsible for the removal of paint and/or rubber stain.
