9-19.1 Surface Applied Detectable Warning Surface
9-19.1(1) General Requirements
The detectable warning surface area shall be yellow and shall match SAE AMS Standard 595, color number 33538. When painting a detectable warning surface is required, such as on a steel detectable warning surface, the yellow paint shall conform to Section
9-08.1(8) and shall match SAE AMS Standard 595, color number 33538.
Units shall be composed of steel, iron, plastics, polymeric materials, resins, pigments. The units shall be uniform in color and texture, be free of cracks or other defects, and have clean-cut and well-defined edges. The detectable warning surface shall meet the following physical properties: Standard Property Results ASTM C501 Wear Resistance Wear Index: >15 ASTM C1028 Slip Resistance Dry Coefficient of friction 0.8 minimum Wet Coefficient of friction 0.5 minimum ASTM E96 Water Vapor Transmission 10 grams/square foot/24 hours Various Adhesion/Bonding Strength See Note* *Note: Due to various types of materials available, the Manufacturer shall certify, through independent laboratory testing, that the type of material used for detectable warnings will adhere to prepared surface.
9-19.2 Cast-in-Place Detectable Warning Surface
9-19.2(1) General Requirements
The detectable warning surface area shall be yellow and shall match SAE AMS Standard 595, color number 33538. When painting a detectable warning surface is required, such as on a steel detectable warning surface, the yellow paint shall conform to Section
9-08.1(8) and shall match SAE AMS Standard 595, color number 33538.
Units shall be composed of steel, iron, plastics, polymeric materials, resins, pigments. The units shall be uniform in color and texture, be free of cracks or other defects, and have clean-cut and well-defined edges. They shall be weather resistant and durable to normal pedestrian wear and maintenance activities, and show no appreciable fading, lifting, or shrinkage. The detectable warning units shall meet the following physical properties: Standard Property Results ASTM C501 Wear Resistance Wear Index: >15 ASTM C1028 Slip Resistance Dry Coefficient of friction 0.8 minimum Wet Coefficient of friction 0.5 minimum ASTM E96 Water Vapor Transmission 10 grams/square foot/24 hours
