Abstract: Molded plastic barrier segments, typically water or sand-ballasted, are engineered to be attached together, end-to-end, in a barrier array, with innovative features which result in low rotation between attached barrier segments. Such a low rotation barrier array will, upon impact by a vehicle, act as a re-directive barrier, rather than a capturing barrier, which is an important safety feature in some crash scenarios.

Abstract: A pedestrian barricade segment is attachable to adjacent similar segments using a hinge construction to form a barricade of a desired configuration. A support leg is rotatable between a stowed and a deployed orientation. A recess is disposed in the segment for receiving the leg when it is stowed. A locking ramp secures the leg in the recess. A foot pocket is disposed in the rear vertical face above the recess so that a user may insert their foot into the foot pocket and use the foot to push the leg downwardly, thereby releasing the leg from the locking ramp for deploying the leg. The leg hinge structure includes a wedge and a wave washer disposed on a flat surface of the block, for securing one end of the leg. The leg hinge structure pre-loads the leg, with the wedge, creating a pivoting bushing surface for rotating the leg.

Abstract: A support stand includes a base, a plurality of legs pivotally attached to the base, a post extending from the base in an upright orientation, and a slider disposed on the post and slidable upwardly and downwardly thereon. The plurality of legs are each connected to the slider so that all of the legs are movable simultaneously to deploy or stow the stand. To deploy, the support stand is placed in a desired location, and the slider is released from a fixed position relative to the post, thereby allowing the slider and the connected plurality of legs to each fall simultaneously to a lower end of the support stand. With the downward movement of the slider, the plurality of legs also pivot to an extended position, with outer ends of each leg disposed on a ground surface to support the support stand. Then, the slider is fixed to the post at a lower end thereof to ensure that the plurality of legs remain in their extended position.

The weed mat further comprises at least one pre-formed cut portion therein for accommodating the post, so that the mat can be secured about the post. A molded-in cut line extends parallel to the edges of the weed mat. The weed mat also includes a molded-in scale system, wherein the molded-in scale system comprises a plurality of additional score lines extending from the molded-in cut line to one of the weed mat edges at pre-determined, measured increments.

Abstract: A system for joining a crash attenuator to a vehicle is operated by moving the crash attenuator into a joining position directly behind the vehicle and dropping a pair of hooks extending from an upper end of one of the vehicle and the crash attenuator over an engagement pin disposed on an upper end of the other of the vehicle and the crash attenuator, so that the hook and the engagement pin are engaged. Two sets of holes disposed on lower ends of each of the vehicle and the crash attenuator are aligned, and a securing pin is inserted through each set of aligned holes, for redundancy.

Abstract: A modular highway warning strip system which comprises a modular warning strip segment having first and second ends, a length extending between the first and second ends, two opposing lengthwise sides, a width extending between the opposing lengthwise sides of the segment, top and bottom surfaces, and a thickness. Each of the first and second ends comprise at least one male protrusion and at least one female receptacle, wherein the at least one male protrusion is configured to engage the at least one female receptacle for joining a plurality of the segments together end-to-end. Advantageously, a plurality of metallic cables are molded into the molded rubber segment and extend along substantially the entire length thereof. One of the metallic cables extends into each of the male protrusions. The cables are preferably formed of corrosion-resistant steel, and preferably are joined together to form a cable mat. The mat is molded into the segment, which segment is molded of rubber.

Abstract: A water-ballasted molded plastic barrier system incorporates barrier segments wherein each segment employs a sawtooth reflective design, designed to prevent the tire of a vehicle, impacting the barrier, from climbing up the side of the barrier segment. Adjacent barrier segments are attached together using an interlocking knuckle design, having a lug pin connection system. Wire rope cable assemblies are internally molded into each barrier segment to create an impenetrable cable fence. The wire rope cable assemblies include steel bushings which are molded into the interlocking knuckles to further strengthen the barrier system.

Abstract: An end treatment array for crash attenuation includes a transition barrier module formed of side walls, end walls, a top wall, and a bottom wall, wherein the module walls together define an enclosed interior space. The end treatment array further includes a containment impact sled having an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module.

Abstract: A trailer-mounted crash impact attenuator is attachable to a host vehicle, which comprises an anti-rotational attachment system having an internal support tube and a plurality of external support tubes. The internal support tube has a connector on its front end for attachment to a suitable receptacle on the host vehicle, and the plurality of external support tubes each have an anti-rotation support pad on their front ends. At least one of the internal support tube and the plurality of external support tubes is comprised of a telescoping construction. A backup frame is disposed on a rear end of the attachment system, and a crash attenuator unit is disposed on an axle and pair of wheels for mobility. When the crash attenuator is impacted by an errant vehicle, the anti-rotational attachment system is actuated to prevent the trailer mounted crash impact attenuator from rotating relative to the host vehicle.

Abstract: A water-ballasted barrier system incorporates a concave reflective design, wherein outer walls of the barrier segment are configured in a concave manner. The concave section is designed to prevent the tire of a vehicle, impacting the barrier, from climbing up the side of the barrier segment, by pocketing the tire in the curved center portion of the barrier wall. Adjacent barrier segments are attached together using an interlocking knuckle design, having a lug pin connection system. In some embodiments, wire rope cable is internally molded into each barrier segment to strengthen the barrier system.
