Abstract: A two-piece, detachable traffic channelization element having an improved base element. The base element has a low profile, dome-like configuration with a ballast storage chamber. The storage chamber may be completely filled with a sand ballast and sealed in its storage condition by a cover secured to the chamber. The base element is molded of a resilient crush resistant plastic so that when it is fully ballasted, need not be ballasted again, and which low profile base can be traveled over by motor vehicles without engaging the base. The detached base, filled with ballast, can be continuously traveled on by motor vehicles, including loaded trucks, without damaging the base element and rendering it useless and the need to be replaced.

Abstract: A modular barrier for attachment to a barricade along a road side for substantially blocking vision toward construction zones or other areas of distracting activity. The barrier includes an elongated base plate with attached support posts which include mounting tracks for insertion of opaque panel members between adjacent posts. Panel edges are configured for tongue-in-groove insertion within channel tracks formed at the lateral sides of each support post. The modular construction of this unit enables quick and economical emplacement at construction areas and other sites where vehicle drivers are prone to distraction by off road activities.

Abstract: A modular element has an internally hollow body (2) made of plasstic material and exhibiting a parallelepiped horizontally-disposed configuration with a transverse section symmetrically diverging from a top portion (4) to a base portion (5). The opposite end surfaces (9, 11) of the body (2) are respectively provided with a coupling lug (8) and an engagement seat (10) matching the shape of said coupling lug. The coupling lug (8) of each modular element (1) is adaped to be fitted in the engagement seat (10) of a contiguous modular element (1b) for the purpose of consecutively connecting several modular elements together. In an alternative embodiment a modular element (12) is provided, at its opposite sides, with two coupling lugs (8) each adapted to be fitted in an engagement seat (10) exhibited by a contiguous modular element (13).

Abstract: A reflective pavement marker of the type having a shell-like housing of synthetic resin or other moldable material with reflective end walls of light transmitting material and a filler of epoxy or other potting material. Ribbing is formed on the inner surface of the housing. The ribbing has a surface that makes an acute angle with respect to the inner surface of the housing to coact with the filler material to increase the resistance to separation of the filler material from the housing.

Abstract: The invention is directed to a light weight, fluid charged, stackable, and easily placeable traffic barrier. The barrier includes a lightweight frame, made up of a skin or other lightweight framing elements. The barrier includes an interior bladder chamber for charging with a weighting fluid.

Abstract: The portable highway barrier of the present invention comprises an elongated barrier body made of lightweight material and having an open cavity therein. The barrier includes an elongated vertical channel at one end and an elongated vertical rib at the opposite end so that a plurality of barrier bodies can be placed in end to end relationship with the rib of one body inserted into the channel of the adjacent body. The barrier can be filled with water or other fluid material once it has been transported to the construction site.

Abstract: An assembly-type barricade comprising a base stand and an upstanding wall both of which are nearly rectangular parallelpipedal. Protruding means is provided in one of the base stand and the upright wall, and receiving means is provided in the other. By positioning the protruding means in the receiving means, the upright wall is detachably mounted on the base stand.

Abstract: A lane barrier system comprises a plurality of pivotally interconnected modules adapted to be transferred on a roadway. Each adjacent pair of modules are pivotally connected together by hinge connections to permit the modules to pivot relative to each other about a vertical pivot axis. A pivot control connected to at least one of the hinge connections permits the pivot axis to move between the modules whereby the modules are capable of elongating or contracting to assume a composite varied length. The pivot control further functions to fix the position of the pivot axis between the modules to rigidify the lane barrier system longitudinally and to place it in tension when lateral loads are imposed thereon, such as when impacted by a road vehicle. The ability of the lane barrier system to elongate or contract is advantageous when the system is picked-up by a transfer vehicle for relocation on a roadway and when the system is positioned at various radii on a curved roadway.

Abstract: The invention is directed to a prefabricated composite pavement device comprising a shaped pavement mixture portion bonded to a support portion and a method and apparatus for making the same.

Abstract: A marker of thick elastomeric sheet material for temporary rested placement on a road surface to indicate a detour lane about a construction site or the like. The marker is of arrow shape. Openings in the marker provide handgrips for convenient handling of the marker during setting out and retrieval of same. A modified arrow is of segmented construction and of variable length and may be placed on a road surface. A further modified marker includes separate head and main body portions which include a coupling arrangement for joining the portions in the field.

Abstract: A movable traffic barrier for dividing adjacent lanes of traffic in a roadway which includes a number of hollow cylindrical barriers laid end to end and projecting above the roadway, and a cable for rotating said cylindrical barriers to position them on the roadway.

Abstract: A transferable roadway lane dividers which consist of individual sections hingedly joined together. The lane dividers are picked up from one side of the lane by a transfer device mounted beneath a vehicle or trailer, travelling along the center of the lane, and are slid along the transfer device and one continuously deposited on the roadway at the desired new position on the other side of the lane.

Abstract: A roadway lane divider comprises a plurality of interconnected divider sections each having a T-shaped upper end. Rollers of a mobile transfer apparatus are adapted for engagement under a pair of longitudinally extending undercut bearing surfaces, defined on the upper end of each divider section, to lift and suspend the divider sections as a unit on a first side of the apparatus, move them serpentine-like across the apparatus and deposit the divider sections on a second, opposite side of the apparatus.

Abstract: A plurality of closely spaced and pivotally interconnected divider sections form a roadway lane divider and barrier. The divider sections are adapted to be lifted and transferred on a roadway as a unit. A plurality of releasable locking members are reciprocally mounted on respective pairs of the divider sections to either lock them together against relative pivotal movement or to selectively release the locking members to permit the divider sections to freely pivot relative to each other when they are lifted for transfer purposes.

Abstract: A traffic guide provision is described with a twosided profile to be employed as a median barrier of roads or with a onesided profile to be employed as road edge barrier wherein the profile is provided with a substantially vertical lower side face (1), via run-up edge (2) followed by an inclined towards the outside running run-up face (3) and above a deflection strip (4) staggered towards the outside relative to the run-up edge (2) and acting upon a vehicle below the automobile body.

Abstract: A tubular synthetic-resin body usable as a roadway marker comprises spaced upper and lower tubular parts interconnected by thin webs formed integrally with the upper and lower parts. A middle part of contrasting color lies between these upper and lower parts and has grooves receiving the connecting webs. Such a roadway marker is made by fitting the middle part over a core of a mold, and then injecting synthetic-resin material into the mold around this sleeve so as to form the upper and lower parts and the web.
