Usage: Historic
Stone unit pavers are known for durability and associated with high-quality traditional streets.
Front Street, Brooklyn
Crosswalk made of granite pavers
Benefits
- Visually enhances crosswalk
- Creates accessible, smooth crossing surface
Considerations
- Significantly higher cost than a standard asphalt crosswalk
Application
- Crosswalks on historic streets or where a Distinctive material is desired and there are low volumes of heavy-vehicle traffic
- Should not be used where frequent utility cuts are likely
Design
Specification source: DOT Standard Specifications Sections 2.06 and 6.04
- Crosswalks generally should comply with MUTCD standards
- Paver size: minimum 4 inches for shortest dimension, maximum 30 inches for longest dimension, minimum 5-inch thickness for vehicular roadbed
- Pavers that have a ratio of length to width greater than 2:1 should only be used when set in poured concrete because of the likelihood of breakage under heavy-vehicle traffic
- Granite must have a textured surface that provides sufficient slip resistance to meet a minimum 0.60 coefficient of friction when wet
- Sustainability opportunity: Salvaged pavers
Maintenance
- DOT maintains this treatment in historic districts
- Use of this material outside of historic districts requires a maintenance agreement
- Due to the possibility of pavers cracking or becoming uneven, and asphalt shoving at the borders, application requires attentive maintenance
