Traffic Circles

Traffic circles are raised islands placed in intersections that slow cars by forcing them to drive around a circle, thus impeding vehicle speed. Traffic Logix SuperFlex curbing can be used to create traffic circles.

Dimensions of the modules:

- width 3.125” (+/- 1/16”)
- length 39” (+/- 1/8”)
- height 4” (+/- 1/8”)

Dimensions of the Traffic Circle:

- minimum inside diameter: 6.5 feet

Material:

Compression molded synthetic and natural rubber

Physical properties:

- density: =68 pounds per cubic foot
- tensile strength: 800 psi
- durometer shore hardness: 70A
- specific gravity: 1.4
- elongation: 160%

Marking:

-	rubber curbs are available in black or red brick color
-	each unit can be marked with either four reflective strips of white or yellow tape 1.5” by 3.75” each

Installation method:

-	each curb unit is affixed to the pavement with three zinc plated steel lag bolts 3/8” x 4”, plastic polypropylene shields and 3/8” zinc plated steel washers supplied with the units
-	9/16” diameter holes are drilled through the holes in the units into a paved road.
-	the plastic shields are installed in the mounting holes with the provided installation tool
-	the lag bolts are inserted into mounting holes and tightened (do not over tighten the bolts)

Installation tools:

-	measuring tape, heavy duty hummer drill, 9/16” dia. by 10” long carbide tip drill bits, installation tool for plastic shields, 11/16” drive socket with a power tool, portable blower, utility knife, crow bars

The first step is to remove any debris off of the roadway where the rubber circle is going to be installed.

Place one end of the rope or cord on the ?X? and the other end on the future perimeter of the circle. Keeping one end of the rope on the ?X? and holding onto the other end of the rope make a circle by marking several locations as you go around. This is a good time to check and make sure the circle is the size that you want it to be.

The next step would be to anchor one piece of our Super Flex red curb on the painted line. Place one end of the rubber curb on the line and drill a hole through one of the three holes found in the rubber curbing. The hole should be approx. 4? deep. Using an air compressor blow out the debris and insert a plastic anchor. Using the anchor installation tool install the plastic anchor through the curbing and into the asphalte.

Install a bolt and washer into the plastic anchor and tighten the bolt. Repeat this process until all of the rubber curbing have been installed.

Sometimes it?s necessary to cut the last piece or two of the red curb in order to get the right fit of your circle.

Some cities have added bricks or asphalt in the center of the circle to beautify the neighborhood as well as to support the vehicles which may inadvertently drive over the circle.

From a safety point of view, steel toe boots and safety gloves are required.
Make sure that the units are tight and well aligned before moving from one step to another.
Make sure the holes are clear of dust and debris before installing the anchors
Remember that all of the bolts need to be installed for the warranty to be in affect.
Traffic Calming devices must be removed in the fall prior to the arrival of snow and installed in the spring after the last snow storm.
Quarterly inspections should be made of each traffic calming device.

In accordance with ITE standards appropriate traffic signs should be installed with each traffic calming device.


	Rubber- Traffic Logix SuperFlex curbing is made from flexible virgin rubber. Rubber is lighter and easier to work with than asphalt and concrete, significantly minimizing the number of hours that need to be invested to install the solutions. Rubber pieces can be pulled up and moved without being destroyed. This is convenient for municipalities that want to institute temporary measures to test an area and is also a safety measure so that products can be stored during the winter to prevent snow plow damage. Unlike concrete and asphalt which necessitate frequent and high cost replacement, rubber products are long lasting and cost-efficient. In addition to long term benefits, rubber products offer a quick, easy way to install solutions when timing is key.

	Easy installation- Traffic Logix Traffic Circles are simple to install. The curb is made so that it can be removed and relocated to an alternate street when needed. This feature is beneficial when a municipality would like to test a number of streets and measure the product’s effectiveness under different circumstances.

	Reflective Tape- Traffic Logix uses a highly reflective tape on its rubber curbing. This tape is a safety feature to ensure that drivers can clearly see the curb both during the daytime and at night. Traffic Logix uses this tape on its products instead of paint since paint often fades away within months and the reflective tape can last for several years. Tape is available in several color choices. Highly reflective cat's eyes can be installed on any device for further enhanced visibility.
