Definitions
- the present invention relates to the field of flexible road joints, of the type comprising a flexible material, resulting from a mixture of aggregates and binder, filling a trench formed in the coating of the road at an interval between two elements of construction supporting the covering.
- Such flexible joints are used, for example, between the successive sections of the bridge deck when the amplitude of the spreading movements (breath) between these sections is not too great. They are an economical solution, and also provide continuity of the running surface and good acoustic comfort.
- compositions used to produce such seals are most often based on a thermoplastic binder.
- European patent application 0 000 642 describes a flexible joint whose binder is based on bitumen and rubbery waste
- French patent 2,562,108 describes a joint whose binder is based on bitumen and of a sulfur vulcanized elastomer.
- Two-component binders are also seen appearing in which the formation of the flexible matrix results from crosslinking of products respectively included in the two components.
- the advantage of these latter formulations is that they can be implemented at room temperature, which simplifies the execution of the work.
- a main object of the present invention is to improve the behavior of such a flexible joint when subjected to tensile forces.
- the invention thus provides a method of producing a flexible joint between two sections of roadway respectively supported by two adjacent construction elements, a rolling surface being formed by a coating deposited on the construction elements and interrupted above an interval separating the two construction elements to form a trench of width greater than that of said interval.
- a sealing element covering said interval is placed at the bottom of the trench, and granules and a binder are poured into the trench which form a flexible material after setting.
- reinforcements are installed in the trench which are attached to the two construction elements on either side of the obturation element, these reinforcements being perforated so as to allow the passage of at least some of the aggregates in the mixture.
- the reinforcements reinforce the joint in areas where the risk of tearing under the tensile stress is greater.
- the fact that the reinforcements are perforated allows the aggregates and the binder to pass on either side of the reinforcement and within it. This results in a good effectiveness of the reinforcement.
- the binder is formed of several components, preferably comprising a polyurethane, mixed and used at room temperature.
- Each frame has a convex portion resting on the bottom of the trench;
- Each frame has a first portion resting on the bottom of the trench and a second portion erected along an end surface of the covering bordering the trench;
- each frame is a piece of expanded metal; - to attach the reinforcements, holes are drilled in the construction elements at the bottom of the trench, metal rods are engaged in these holes leaving their upper ends protruding through the openwork reinforcements, and the upper ends of the rods above the frames; - the sealing element is coated with grease; - the closure element comprises at least two superposed sheets, which are arranged so that they overlap in the direction perpendicular to the interval separating the two construction elements and that the lateral edges of the element obturation, arranged substantially parallel to the interval, belong to separate sheets. One of the sheets is preferably arranged so as to cover the entire gap separating the two construction elements.
- Another aspect of the present invention relates to a flexible road joint between two sections of road respectively supported by two contiguous building elements, a rolling surface being formed by a coating deposited on the building elements and interrupted above 'an interval separating the two construction elements to form a trench of width greater than that of said interval.
- the flexible joint is located in the trench and includes a sealing element covering said gap at the bottom of the trench, and a mixture of aggregates and flexible binder. It also comprises openwork reinforcements, attached to the two construction elements on either side of the closure element and embedded in the mixture of aggregates and binder.
- FIG. 1 is a cross-sectional view of a flexible joint executed in accordance with the invention.
- FIG. 2 is a partial cross-sectional view of an alternative embodiment of the seal.
- the roadway shown at a joint in Figure 1 is built on elements 1 which are for example concrete.
- the elements 1 can be sections of the bridge deck and / or abutments. Displacements may occur between the contiguous elements 1, so that an interval is left between them, the thickness e of which typically varies between 10 and 60 mm.
- a conventional coating 2 is deposited on the elements 1.
- This coating 2 is interrupted above the interval between the elements 1, in order to define a trench of width L greater than e .
- the width L of the trench distributed symmetrically on either side of the interval e, can be from 25 to 70 cm.
- This trench is intended to receive the flexible joint according to the invention, which comprises a mixture 3 of aggregates and flexible binder, an element 4 for closing the gap e, and reinforcements 5.
- the binder used in the flexible material 3 can be of any known composition. In a preferred embodiment, it is a two-component binder, which forms a flexible matrix by chemical reaction at room temperature between molecules included in the two components. This matrix can in particular be based on polyurethane, supplemented with bitumen.
- the closure element 4 is a metal sheet placed on the interval e at the bottom of the trench. It prevents the aggregates and the binder from infiltrating in this interval. The underside of the sheet 4 also allows sliding of the concrete elements 1, in order to distribute the compression of the joint over a greater width. The width of this sheet 4 is for example from 10 to 35 cm.
- the reinforcements 5 are arranged on each side of the trench, on either side of the sealing plate 4. These reinforcements 5 are perforated so as to allow at least some of the aggregates from the mixture to pass through. Thus, certain coated aggregates of binder pass behind the frames 5, and others remain in the openings which they comprise. After the binder has set, the reinforcements 5 are therefore firmly held in the flexible material 3.
- the reinforcements 5 are attached to the concrete elements 1 on each side of the trench, in order to offer a resistance to tearing of the flexible material 3 of the joint in the areas where it is stressed in tension when the elements 1 tend to s' move away from each other.
- FIG. 1 illustrates a simple and convenient means of attaching the reinforcements 5.
- First cylindrical holes 6 are drilled in the concrete of the elements 1, then metallic rods 7 are engaged in these holes 6.
- the rods 7 have for example a diameter slightly greater than that of the holes 6 into which they are forcibly inserted.
- the upper end of the rods 7 is allowed to protrude into the trench, and when the reinforcements 5 are placed, the protruding ends of the rods 7 are passed through the openings present in the reinforcements 5.
- the upper ends of the rods 7 to hold the reinforcements in place 5.
- FIG. 1 also shows a preferred profile of the reinforcements 5 which, in general, will extend over the entire length of the joint (perpendicular to the plane in Figure 1).
- the frame 5 is preferably made from a sheet or grid of expanded metal having apertures of appropriate size (a few centimeters) and shaped according to the profile shown.
- a first portion 5a of the frame rests on the bottom of the trench, between the shutter plate 4 and the edge of the covering 2.
- This portion 5a has a convex shape, in order to allow the passage of the material 3, including the aggregates, between the reinforcement and the surface of the concrete element 1.
- the convex portion 5a has a typical height of 2 to 3 centimeters. It allows any traction forces to be transmitted to the flexible material 3 before its interface with the coating 2. As it is near this interface that the risks of tearing are greatest, this results in better resistance of the joint.
- a second portion 5b of the frame is erected along the end surface of the covering 2 bordering the trench. This portion 5b makes it possible to arm in its most fragile zone and to distribute the reinforcement over its thickness.
- the width of the first portion 5a is for example from 8 to 10 centimeters, and the height of the second portion 5b can be of the order of half that of the covering 2.
- the material 3 is installed.
- One can for example spread a layer of aggregates then pour the binder prepared in the fluid state until completely drowning the layer of aggregates, and repeat the operation until reaching the surface of the covering 2.
- a layer of gravel 8 is then spread in order to give the joint a surface appearance similar to that of the covering 2.
- the closure plate 4 is advantageously coated with a grease, for example silicone, to facilitate the sliding of the concrete elements 1 and to avoid the adhesion of the material 3. Of course, it is necessary to ensure that this grease does not overflow next to the sheet. It is advantageous to provide that the sheet 4 is relatively wide, in order to distribute the compression of the joint over a greater width. However, it is preferable to prevent the edges of the sheet 4 from abutting against the reinforcements 5 when the elements 1 come together.
- a grease for example silicone
- this closure element can subdivide this closure element into two superimposed parts (or more), arranged parallel to the gap between the two concrete elements 1, so as to overlap in the direction perpendicular to this interval, as illustrated in FIG. 2.
- the lateral edges of the closure element composed of the two sheets 4a, 4b belong to separate sheets.
- the larger sheet 4a rests on the two elements 1, and is covered by the narrower sheet 4b which protrudes at one of the ends.
- adhesive tape 9 can be used.
- the two sheets 4a, 4b coated with grease can slide one on the other, which prevents them from coming up against the reinforcements 5.
- This arrangement also prevents the lateral edges of the closure element from tending to punch or excessively deform the flexible material 3 when the elements 1 come together.
