CONCRETE BUTTONS

ARMADILLOS Typical Dimensions: 32 in. long x 8.5 in. wide x 5 in. tall. Requires min. of 1.5 ft. of buffer area width (must be placed diagonally).

Typical Dimensions: Varies. Can be 3 in. or 5 in. high, and up to 1 ft. wide. Estimated Cost: $12 / 3” unit; $15 / 6” unit (assumes bulk order).

Estimated Cost: $40 / 3” unit; $50 / 5” unit, depending on size and quantity ordered.

Overview: Often used as barrier near light rail tracks, these low, mountable buttons can be used to achieve a curb-like barrier effect for curb extensions and plazas.

Overview: Low, mountable and durable, this plastic bump that can be used to achieve a curblike barrier effect.

Demo (1 day - 1 month)

F Pilot (1 month -1 year) F Interim (1 - 5 years)

Recommended Applications and Installation ɖBikeways: ɖ Place along edge of lane, 1 every 5 - 8 ft. Note that given the low and mountable profile, spacing beyond 8 ft. apart may not be effective in deterring vehicles from entering the bike lane. Installation does not require specialized equipment. Simply drill holes in the asphalt / concrete and install. A team of three people can install approximately 100 meters in 8 hours. The product’s pre-sunk bolt holes can accommodate anchors of various sizes. Tips and Considerations »» Easily Installed and removed. »» Durable and meant to last several years. »» Mountable, allowing emergency and, city service vehicles access. »» Minimal / no stormwater obstruction. »» Set armadillos at an angle to allow cyclists to cross between barriers as necessary. »» Low visual profile may lead to a decreased safety perception of safety for people walking or biking (compared to vertical delineators, posts etc.). »» Manufacturer recommends using mechanical anchors with chemical adhesives. Plastic mechanical anchors are not recommended. Potential Sources »» Purchase from traffic control or construction equipment suppliers.
