Benefits
See benefits of Unpigmented Concrete
- Can enhance or reinforce the character of a block or public space
- Less expensive than unit pavers
Considerations
See considerations of Unpigmented Concrete
Application
- Because this is a Distinctive sidewalk treatment, it is best used when applied to entire blocks, rather than to the sidewalks of individual small properties which would create a “patchwork” effect
- Requires PDC approval
Design
Specification source: DOT Standard Specifications Special Section 6.06 LP
- See design guidance for Unpigmented Concrete
- Flag Size: dimensions may vary depending on pattern
- Avoid excessively small dimensions or acute angles that may result in pavement failure
- Careful consideration must be given to transition areas or interactions with other streetscape elements to avoid small/easily deteriorated portions of concrete
- Concrete can be unpigmented, pigmented or exposed aggregate
- Joints may be tooled or saw-cut depending on desired effect
- Example pattern: London Paver Scoring with a flag size of 18 inches by 36 inches; joints must be saw cut to ¼ depth of pavement
- Sustainability opportunity: Supplementary cementitious materials (SCM)
- Sustainability opportunity: Recycled concrete aggregate (RCA)
