Abstract: A peelable roadway marking tape has a multi-layer structure which provides durability and ease of removal. The marking tape includes a top layer of pigmented vinyl paint with reflective glass beads incorporated therein applied to an intermediate backing layer of either aluminum or vinyl. The backing layer is then laminated to a polyester mesh reinforcement layer, and a pressure-sensitive adhesive hot melt is applied to the under side surface of the mesh for attachment to the roadway surface. In an alternate embodiment of the invention, a layer of high density polyethylene is laminated between the mesh layer and an aluminum backing layer.

Abstract: An improved two-piece, detachable traffic device features a high-density, low-profile solid base. The base is, preferably, made of a molded unitary composition made of recycled rubber products, such as, spent motor vehicle tires. Further, it is molded such that it can be stacked for ease of storage with similar bases. The combined high-density and low profile flexible aspects of the base cooperate to ensure both that the base remains stationary during use and can easily be traveled over by a vehicle without damage resulting to the base or the vehicle. The mass of the base is concentrated at the periphery of the base to maximize the self-righting effect of the base while minimizing the over all weight of the base and material required.

Abstract: Roadway traffic control marking tape and reflective sheeting are known in the art for providing temporary delineation and demarcation of traffic lanes in order to guide the flow of traffic through detours, construction areas and the like. Traffic channelizers and barricades are also well known in the art as barriers to discourage crossing the lanes onto the other side thereof. When work on highway lanes is completed, and traffic is redirected to newly opened lanes, the tape is generally removed. When it breaks during removal the job is particularly demanding. Damage to traffic channelizing devices which are hit by fast moving vehicles leads to their frequent replacement. Hence it has become desirable to recycle them. The recycling process requires that the reflective sheet first be removed. But the recycling process too has been hampered by the difficulty of sheet breaking during its removal.

Abstract: Traffic control devices are employed for providing temporary delineation and demarcation of traffic lanes in order to guide the flow of traffic through detours, construction areas, and the like. Normally, ballasts used with traffic control elements have been bags containing a stabilizing material such as sand. Such traffic control elements are subject to improvement. They do not permit the stabilizing material to be spread uniformly across the bottom of the traffic control element. Sandbags become lodged against one side of the traffic control element during assembly, or they are thrown against one side on impact. And none of the stabilizing materials in use lend themselves to disassembly and transportation when the traffic control elements are moved to a new hazardous site. Such shortcomings are overcome by the improvement herein.

Abstract: A sign stand for supporting signs in windy environments includes a base, a staff portion extended from the base and an upper portion for receiving and displaying a sign. The sign stand includes a mechanism permitting pivoting of the sign to spill wind load and includes a mechanism for applying a restoring force to restore the sign to its normal vertical position on removal of the wind load. The restoring mechanism may be incorporated in the base structure and can utilize a tension spring to provide the restoring force.
