Description
Truncated-dome tactile warning pattern for pavement
Uses:
Use either the SSTD-Traditional Mat System or the SSTD Ramp Up Mat where ADA, transit, or building codes require a tactile warning surface, such as at transit boarding platforms, curb ramps, and hazardous vehicular areas. The system may be installed directly on concrete or asphalt.
Product Attributes
The system consists of a patterned mat plus adhesives and coating to form an ADA compliant high-contract, breathable surface
SSTD easily handles curves, pavement joints, and concrete-asphalt transitions.
Applicable Standards
SSTD is compatible with: ADA Accessibility Guidelines (ADAAG) Section 4.29.2
