Traffic Calming

Here is an attractive traffic calming installation using differing natural materials to make a visual barrier; create a rough texture with a slight hump; and increase road noise.  This has a nicer appearance than a yellow speed bump or hump. A raised crosswalk is another calming technique.  The raised sidewalk could be constructed with similar materials on the ramps.  We have seen similar installations using split paver blocks with the broken ends placed as the surface. If used in asphalt concrete roads, the different materials must be embedded in a PCC bed to hold the materials in place. For durability, make the concrete bed at least eight inches thick.
