SECTION 726 - DETECTABLE WARNING UNITS
726-01 Surface -Applied Detectable Warning Units
SCOPE. This specification covers the material and quality requirements for surface -applied detectable warning units. MATERIAL REQUIREMENTS. Surface -applied detectable warning units shall conform to the dimensions shown on the current standard sheet for detectable warnings. Units shall be composed of cementitious materials, steel, iron, plastics, polymeric materials, resins, pigments, or as ap proved by the Director, Materials Bureau. The units shall be an approximate visual match to the color specified in the Contract Documents. Units shall provide the required contrast (light - on-dark or dark -on-light) with the adjacent curb ramp or other app licable walkway. The units shall be uniform in color and texture, be free of cracks or other defects, and have clean -cut and well -defined edges. Units shall adhere to asphalt or Portland cement concrete (PCC) surfaces at a minimum air temperature of 60°F, and a minimum surface substrate temperature of 70°F. They shall be weather resistant and durable to normal pedestrian wear and maintenance activities, and show no appreciable fading, lifting, or shrinkage. The units shall be capable of molding or fittin g itself to the contours, breaks, and faults of asphalt or PCC surfaces, and show no significant tearing, rollback, lifting, or other signs of poor adhesion. The units shall have friction characteristics similar to a broomed PCC surface. The detectable war ning units shall meet the following physical propertie s: Standard Property Results ASTM C 501 Wear Resistance Wear Index: >15 ASTM C1028 Slip Resistance Dry Coefficient of friction 0.8 minimum ASTM E 96 Water Vapor Transmission 10 grams/square foot/24 hours Various Adhesion/Bonding Strength See Note* *Note: Due to the various types of materials available, the Manufacturer shall certify, through independent laboratory testin g, that the type of material used for detectable warnings will bond to a prepared surface. PACKAGING AND SHIPMENT. Preformed, surface -applied, detectable warning units shall be shipped and packaged in accordance with commercially accepted standards. The following information shall be marked on each package or on the shipping invoice: the name of the product, the name and address of the manufacturer, and the quantity of material. BASIS OF ACCEPTANCE. Acceptance of this material for placement on the Approved List will be based on the manufacturer’s certifica tion of compliance with these requirements and in accordance with procedural directives of the Materials Bureau. Contract acceptance will be based on the manufacturer’s name appearing on the Department’s Approved List.
726-02 Embedded Detectable Warning Units
SCOPE. This specification covers the material and quality requirements for embedded detectable warning units.

Units shall be composed of cementitious materials, steel, iron, clay, shale, plastics, polymeric materials, resins, pigments, o r as approved by the Director, Materials Bureau. The units shall be an approximate visual match to the color specified in the Contract Documents. Units shall provide the required contrast (light -on-dark or dark -on-light) with the adjacent curb ramp or ot her applicable walkway. The units shall be uniform in color and texture, be free of cracks or other defects, and have clean -cut and well -defined edges. Where applicable, the units shall adhere to asphalt or Portland cement concrete (PCC) surfaces at a minimum air temperature of 60°F, and a minimum surface substrate temperature of 70°F. They shall be weather resistant and durable to normal pedestrian wear and maintenance activities, and show no appreciable fading, lifting, or shrinkage. The units shall ha ve friction characteristics similar to a broomed PCC surface. The detectable warning units shall meet the following physical properties: Property Results Compressive Strength, Min., 28 days 8000 psi Minimum Freeze -thaw Loss (25 Cycles, one per day, 10 % NaCl solution) in accordance with NY Test Method 502 -3P 1.0 % Maximum PACKAGING AND SHIPMENT. Embedded detectable warning units shall be shipped and packaged in accordance with commercially accepted standards. The following information shall be marked on each package or on the shipping invoice: the name of the product, the name and address of th e manufacturer, and the quantity of material. BASIS OF ACCEPTANCE. Acceptance of this material for placement on the Approved List will be based on the manufacturer’s certification of compliance with these requirements and in accordance with procedural directives of the Materials Bureau. Contract acceptance will be based on the manufacturer’s name appearing on the Department’s Approved List. SECTION 727 - PAVEMENT MARKING MATERIALS (Last Revised September, 2016 )
