Abstract: A cathodic protection test station device has a terminal board integrally formed with a base plate. A removable housing locks onto the base plate and covers the terminal board and the base plate. A tab formed in the base plate extends into a recess formed in the housing defining a locking position. A tool may be inserted in an access slot formed in the housing to deflect the tab and remove the housing. A plurality of first wedge members are symmetrically disposed on a bottom surface of the base plate. The first wedge members have an inclined surface that slidably engages an inclined surface of a plurality of second wedge members. A bolt extends through the base plate and the first and second wedge members to a nut held in a non-rotating manner in the second wedge member. As the bolt rotates, the nut moves towards a head of the bolt and urges the first and second wedge members axially together.

Abstract: A channel structure for housing electrical wires and supporting glarefoil blades along a median barrier of a divided highway or other roadway. An elongate composite channel structure defines an interior channel and a flat exterior top support surface. The composite channel is attachable to the top of a median barrier to cover electrical streetlamp wiring extending along the top of the barrier. A series of glarefoil blades are attachable directly and individually to the flat top support surface so that the support surface is the only object which provides structural, stabilizing support for each of the glarefoil blades.

The device includes at least one elongated tubular member of fiber reinforced, thermosetting resin formed by pultrusion and having a hollow interior able to receive sound absorbing material. The hollow interior is filled with sound absorbing material including particulate, recycled polymer firmly compacted within and substantially filling the hollow interior of the tubular member.

Abstract: An asphalt pavement material comprising an aggregate mixture of asphalt, gravel, sand and a pelletized composite of recycled rubber and thermoplastic material. The pelletized composite has a uniform size, smaller than the gravel and larger than the sand and is configured to fit within interstitial voids between the gravel. Sufficient pelletized composite is added to the asphalt pavement and mineral aggregate mixture (replacing mineral aggregate of comparable size) to substantially fill void spaces between the gravel.

Abstract: A sound wall for placement along a roadside for reducing the transmission of sound from a traffic area wherein the sound wall comprises a plurality of stiff, resilient containment members respectfully configured with the channel configuration and having an enclosed channel volume and continuous open side. Each channel volume is filled with a composite composition of rubber chips and binder compressed within the channel and substantially filling the channel volume. These containment members are stacked in nesting relationship to form a wall structure, with the open side being oriented toward the traffic area.

Abstract: A device is provided preventing the transmission of sound, the device being fabricated of polymer composition and comprising a hollow core member formed of fiber-reinforced thermosetting resin, and at least outer member formed of unreinforced thermoplastic resin which is friction fit to the core member. The core member and outer members are preferably formed by pultrusion and extrusion, respectively. Adjacently disposed devices are connected together to form a fence-like barrier through which few or no sound waves are allowed to pass. This system is advantageously used to prevent sound waves emanating from a large transportation structure such as a highway, railroad track, or airport.

Abstract: A tamper resistant sign for flush mounting to a wall or substantially flat surface comprises an elongate, one piece, extruded or pultruded frame. The frame has a back wall and a pair of ribs extending backwardly from respective lateral side edges of the back wall. A pair of open sided channels are positioned along the side edges of the frame. The open sides of the channels face each other and have a clear plastic faceplate positioned therebetween, with the opposite lateral sides of the faceplate being received longitudinally within the respective channels. Molded end caps are provided that seat firmly against the back wall and channel of the frame to close the opposite ends of the sign. The end caps fit securely and tightly in the channels and against the back wall of the frame.

Abstract: An adjustable glarefoil assembly is provided for mounting to a median barrier which divides opposing lanes of a highway and operates to reduce the glare of headlights from oncoming vehicles. The glarefoil assembly includes a plurality of glarefoil blades which are adjustably coupled for angular movement with respect to a base runner section in an appropriate light blocking orientation. The base runner section is rigidly mounted to the top of the median barrier at between three and five spaced points, thereby preserving some latitude for vibrational movement within the base runner section. The glarefoil blades are each adjustable about a vertical, longitudinal axis so as to optimally provide sight obstruction for a variety of different road curvatures, as well as maintaining the best possible angle to prevent wind build-up.

Abstract: A delineator device having high visibility and utility for attachment to a paving surface such as a median curb or other dividing area between two lanes of traffic. The device includes an integral base member and vertical support member having a top and a bottom end and intermediate section including an elongated concave-convex structure. The bottom end of the vertical support is coupled to an upper face of the base to provide support for an attached horizontal member at the top end of vertical support member. This horizontal member includes top and bottom edges and an intermediate section which is also of concave-convex structure. A receiving base is provided for insertion of a projection tab section which extends downward from the base member. Locking flanges are attached to the tab to enable the device to be secured in its inserted position.

Abstract: A collapsible barricade comprising a rigid cross-member coupled by an elastic joint to at least one pair of rigid legs. The elastic joint is developed by a flexible, elastic, resilient connecting member which is attached at one end to the cross-member and at the other end to the rigid leg in a manner such that the formed elastic joint is capable of stretching under stress to allow the pair of legs and attached cross-member to deform from a sturdy configuration when subjected to an impact by a vehicle or other moving object. The collapsible barricade can then be restored to its sturdy condition by merely repositioning or reattaching the connecting members to the respective legs and cross-member and by repositioning the deformed structure to its original configuration.

The detachable base includes a deformable, domed structure comprised of a top, intermediate body wall and base attachment channel. The base attachment channel includes first and second channel walls, and a third radial flange which projects inward from the second channel wall toward a central axis of the domed structure. Accordingly, three (3) enclosing walls define a channel enclosure which is utilized to retain the domed structure in attachment to a rigid base plate. The base plate has a vertically oriented lip at its perifery which is adapted in size and configuration for a tight, contour fit within the channel enclosure.

An opening in the longitudinal rib provides access to the core to enable physical contact (37a, 38a) for measurement of electrical properties as conducted from the underground pipe through the wire into the terminal support.

Abstract: A road-surface mountable delineator support member constructed of resilient wall structure of flexible material whose structure is capable of maintaining an attached delineator in upright, operational orientation as a traffic guide and capable of surviving repeated vehicle impacts. The wall structure is sectionally comprised of an integrally formed neck, shoulder and larger collapsible body in which most of the vehicle impact forces are transferred to the larger collapsible body section which deforms in preference to deformation of an attached delineator structure. The support base can be adhesively attached to a road surface and can be adapted for attachment of tubular delineator structures with various reflective format.
