Abstract: A removable speedbump-cover comprising an elongated laterally arcuate panel which is designed to rest on its elongated edges on the surface of a driveway. Gusset plates extend transversely of the panel on its concave side. The lower edges of the gusset plates are spaced slightly from the surface of the driveway so as not to interfere with the mounting of the panel. The panel is sufficiently flexible to permit the lower edges of the gusset plate to come into contact with the surface under load.

The opening is in communication with the first chamber and a second side in generally opposed relationship to the first side, the body having a second retention chamber adapted to receive a joinder member in engaging relationship therewith, the second side having an opening therein in communication with the second retention chamber, the opening forming a restricted mouth with the second chamber.

Abstract: Procedure of locating expansion joints (7) in a concrete bed (3,4) during manufacture (casting) by locating pre-fabricated joint elements (11,12) consisting of long rails made of reinforced concrete in pairs as a form and glide path (1,2) for smoothing and vibrating machines and in such a way that the cavity formed is filled (7) with material which has a lower E-modulus than concrete. The procedure also describes a method when two rails are secured to another by means of an adhesive. The rails (11,12) are designed to form a tongue and groove (9,10) between the rail concerned and the associated concrete slab (3,4). Holes are made for dowels (6,8) which extend from one slab to the other through the joint element and thus prevent edge raising from occuring later on.

Abstract: Expansion and cast-in retainer dams for sealing pavement joints against intrusion of water, dirt, etc., into the joint space, said dams utilizing a pair of extruded steel or aluminum frames on opposite sides of the joint and a continuous elastomer strip spanning the joint and interlocked along its opposite edges in slotted longitudinal openings in the frames by a bead of triangular cross-section on each edge of the strip, the frames each having elongated solid metal zones above and below the slotted openings.

Abstract: An expansion joint sealing assembly of the type employing a flexible membrane extending between two relatively rigid elongated elastomeric pads is adapted to seal the gap in the area where a curb and roadway portion of the deck intersect. The assembly is especially useful in situations where the gap extends at a skew angle across the roadway, so that the line of intersection between the curb and roadway portions of the deck, along which the sealing assembly must be bent, is not perpendicular to the longitudinal dimension of the sealing assembly. This creates a complex bending angle for the flexible membrane portion of the seal. In brief terms, the problem is solved by providing laterally extending convolutions in the side edge portions of the membrane and a locking rib on the top of each convolution which fits into an appropriate slot in the elastomeric pad to which each side edge portion of the membrane is connected.

Abstract: A method of sealing bridge deck joints on a highway in which the deck members have the road surfacing material removed therefrom and a flexible composition of chips of aggregate in a rubberized binder, such as bitumen, pitch, pitch-tar or tar is inserted in the removed area as a resilient sealing material.

Abstract: An expansible caulking material in strip form is disclosed suitable for use in sealing joints between vertical panels, and packing wide expansion joints occurring in decks of parking garages, bridges, airport runways and the like, with a shortened expansion time particularly for use in cold locations where the expansibility by reason of the adhesive impregnant would be unduly delayed. The caulking material comprises compressed and expansible strips of open cell plastic foam with one or more wires or strips therewith with the foam normally retained in compressed condition until ready for use, and in which an electric current is applied to the ends of the wires or strips to supply heat to speed up the expansion.

Abstract: An assembly is provided for weather-sealing an elongated joint formed between a first member and a second member when said members are disposed at a predetermined relative position. The assembly includes an elongated piece having elongated interconnected first and second sections extending angularly relative to one another. The piece is removably carried by an elongated bracket fixedly secured to a side of one of the members defining the joint. The bracket is provided with an inner wall section, an outer wall section in spaced substantially face-to-face relation with the inner wall section, and a bridge section interconnecting a pair of corresponding elongated edges of the wall sections. The wall and bridge sections coact to form an elongated pocket having a first opening at one end. Corresponding second elongated edge portions of the inner and outer wall sections are disposed in spaced relation and define an elongated second opening having an end terminating at the first opening.

Abstract: The use of flake glass in road pavement and repair is disclosed.

Abstract: A clip is disclosed for insertion in a hole in the side of a paving form. A paper sleeve, diamond-shaped or rectangular in cross section, covers one leg of a tie bar, and the sleeve is supported in the clip. After a slab is poured and the form is removed, the clip and hole identify the position of the tie bar, which is pulled outwardly in preparation for the next pour. The rectangular protective sleeve can be used without the clip, in that it positions the leg of the tie bar closely adjacent the paving form, without the interposition of extra concrete around the edges of the sleeve.

Abstract: A concrete control joint is characterized by a substantially T-shaped member having a slit extending substantially vertically through the upright member of the T to define first and second leg portions thereof. The lower ends of each leg portion are resiliently and hingedly connected together. An arm of the T is connected to the end of each leg portion opposite the hinged connection. The arms terminating in fingers which extend substantially perpendicular from the underside of the arms in a direction substantially parallel to the leg portions toward the hinged joint therebetween.

Abstract: A method of forming a carriageway slab comprising two or more sections with expansion joints between the sections and stressed longitudinal tensioning members extending all the way through the sections is provided. In such structures, the space between sections where the expansion joints are provided is too small to insert a press to provide necessary stress to the longitudinal tensioning members. According to the invention, the tensioning members are formed in two parts, one part of each (a longer part) extending rearwardly from the front end plate of a section and the other or shorter part extending from the rear end plate. The front portion of the section is concreted and when the concrete is hardened, the tensioning members are stressed at the end of the concreted part and fixed in stressed condition, then the shorter parts of the tensioning members are attached to the corresponding longer parts and tension is applied to the shorter sections while the position of the adjacent ends at the joint is fixed.

Abstract: The disclosure relates to a joint-edge element for expansion joints in roadways wherein the anchoring parts, that extend in the longitudinal direction of the joint, just as the remaining parts of the joint-edge profiled element, are joined in one piece to the joint-edge element. At least one profiled part of the joint-edge element is produced by dividing the double profiled element in two profiled halves. Joint-edge elements having the double length of the particular extrusion casting or rolled element are produced through a single operation of extrusion or rolling.A particularly expedient embodiment is produced in such a manner that the anchoring parts are formed by parting a connecting portion of the double profiled element. The parting operation can be performed without considering the precision of manufacture, with relatively low expenditure.

Abstract: A buried expansion joint for use in the construction of bridges incorporates a pad of flexible plastics material, such as neoprene, located over an expansion gap between structural members and a flashing of neoprene or other plastics material extending over the pad and stuck to the structural members by adhesive bedding. The pad may have channels or voids extending along its transverse dimension adjacent its edges which in conjunction with aligned grooves in its upper and lower surface provide a corrugated web section allowing compression longitudinally of the structural members without any substantial increase in vertical compressibility.

Abstract: End dam assemblies for sealing a gap between adjacent roadway or deck slabs comprise a series of elongate elastomeric end dam sections which are assembled in end-to-end array. The end dam sections are provided with layers of porous material which confront and engage each other when adjoining end dam sections are secured together. The layers of porous material enhance securance of the end dam sections to each other by providing an auxiliary material on each end dam section which is more easily bonded to the end dam sections and to each other than are the adjoining end dam sections directly to each other. The layers of porous material may also provide mechanical resistance to relative movement of the end dam sections.
