A device for attachment to a road or carriageway comprises a solid mass made from aggregate and a binder material preferably asphalt or bitumen. The device may be a preformed portion of a speed cushion or a road hump, where two or more devices are attached to the road to form a discreet traffic calming obstacle. The surface of the device is skid resistant. The device is made using a mould into which is placed a heated mixture of aggregate and binder. This mix is allowed to harden and is then removed from the mould. To lift the device, attachment points are provided in the form of removable lifting eyes. The device can then be readily transported to the location for installation, where it can be easily handled into place after adhesive is applied to the road surface or the device itself. The adhesive used is preferably a rapid curing resin such as polyurethane. |
