To solve the problem, in particular in outer layers of porous asphalt in road construction to provide a system by means of which the drainage of roads is not substantially impaired, a similar system for road construction for closing joints with joint edges and a joint bottom is proposed comprising at least one potting material and at least one element which can be arranged at the bottom of the joint, comprising a main body and a first part facing the potting material, which is substantially impermeable to the potting material, and wherein the element enables the outflow of water.
The The present invention relates to a system for road construction for closing joints with joint edges and a joint bottom as well the use of such a system.
To the Closure of joints in road construction are especially joint tapes known, which for the production of seams and connections be used. Seams occur in a composite of adjacent installation strips of mix with comparable Properties while as connections connections of one-way webs of mix with different properties called become. An example of this is a connection of rolled asphalt Mastic asphalt and vice versa. Connections form in particular even when building "new" versus "old", because only by the duration of the old installation track a difference in the characteristics to the new installation tray to be introduced respectively consists of the cover sheet material used for this purpose. Such a building old against new finds not only in a fundamental Renovation of paving, but also in the context of smaller or major repairs of installation panels or when closing trenches instead. there can also be provided that not producible in a single operation installation rails be divided into several smaller sections, in which case again the need for a particular sealing connection of the Installation track made of the new cover layer material to the existing installation track consists. But also in the adaptation of fixtures such as covers of Wastewater connections such as manhole covers or slide flaps and at marginal enclosures arise connections, which are closed Need to become.
Except Joint tape is used to seal, in particular, seams also the use of cold or hot processable potting compounds known. The joint tapes as well as the potting compounds point while predominantly a bituminous base, wherein However, especially for cold processable casting compounds and such can be used, which do not comprise bitumen.
By the known from the prior art joint strips and Casting compounds is a running over the entire joint depth Created area, which is substantially impermeable to water is. If necessary, cracks, which in case of improper processing can emerge, enable the unwanted Passage of water, but possibly also of other liquids, as in case of accidents leaked gasoline or engine oils.
Become However, known from the prior art joint strips or potting materials used for the production of Seams or connections in water-permeable Installation trays, which under the terms drainage asphalt respectively Flüsterasphalt are known and made of open-pore surface layer materials (open-pored asphalt (OPA)) can be created in the worst case by means known from the prior art Techniques, especially at a sufficient joint depth, a drainage prevented due to the joint tapes or Casting materials formed barrier. Road surfaces with water-permeable paving include a water-permeable Thick film under which a binder layer is arranged, whose Surface substantially impermeable to water for the discharge of water along the example road slope is trained. Because of this barrier and the existing Gradients can therefore be the water-permeable cover layers be drained.
It is therefore an object of the present invention, a solution to provide by means of which joints in road construction especially when using water-permeable road building materials a drainage is possible.
This object is achieved by a system for road construction for sealing joints with joint edges and a joint bottom, comprising at least one potting material and at least one can be arranged at the joint bottom element comprising a main body and a first, the potting material facing part, which for the potting material substantially is impermeable, and wherein the element allows the outflow of water. The potting material can be a cold, but also hot processed potting material. Preferably, the potting material is one with a bituminous base, wherein preferably polymer-modified bitumen is used, ie a bitumen, which has been adjusted by the addition of plastics. However, it is also possible to use a pure bitumen, also mixtures of at least one bitumen with at least one polyurethane, also emulsions, but also in particular mixtures of different bitumen and in particular mixtures of polymer-modified bitumen. The bituminous material used may in particular also comprise fillers, such as mineral rock minerals or fibers. The potting material preferably has a cone penetration [1/10 mm] according to BS2499-3 (TP2.4.6) in a range of 50 to 300, preferably 50 to 220, still more preferably 50 to 100 on. Furthermore, the potting material preferably has a softening point RuK according to DIN EN 1427 of at least about 70 ° C, more preferably at least about 75 ° C, even more preferably at least about 80 ° C. Hot-processable grouts can be used in all types of traffic areas, ie those made of concrete and / or asphalt. Cold applied joint compounds can also be used, but are preferably used in traffic areas made of concrete. Cold-processable joint compounds in the context of the present invention are reactive, without heat input installable one- or two-component system with predominantly elastic properties, with particular preference being given to polyurethane-based. These preferably have a stretch and adhesion (Dehnspanne) according to DIN EN 28340 at 23 ° C of at least about 0.15 N / mm 2 , more preferably at least about 0.2 N / mm 2 . Preferably, cold workable joint compounds have a resilience according to DIN EN 27389 of at least about 70%, preferably at least 80%.

The further encompassed by the system according to the invention Element comprises a main body and a first, the Potting material facing part, which for the potting material is essentially impermeable. This first part of the Element's purpose is a complete backfilling a joint with the system of the invention continue to prevent potting material, which then Finally, a completely impermeable Barrier would be created. Furthermore, by this first part of the element with a suitable training of the same created a free space of whatever kind, through which water can run off, leaving no barrier in a topcoat here is created for water, and this in the direction of run down the slope above the barrier layer and thus the roadway can be drained.
The element comprised in addition to the first, the casting material facing part, a second, the joint bottom facing part. The first and the second part can together form the entire height of the element, but even between these still another area can be created. The first and the second part can in particular also be completely accommodated in the base body, but also adjoin or extend beyond it. It is preferably provided that the first part is at least partially formed by the top of the body, more preferably, the first part can extend over a thickness of up to 10%, based on the total height of the basic body of the element. The first part may preferably be formed of bituminous material, but it can also be made of any other, a flow through the potting material preventing material. Preferably, when bituminous material is used for the first part of the element, it differs from a bituminous material used in the potting compound. In this case, the bituminous material used for the first part preferably has a softening point RuK DIN EN 1427 of at least about 90 ° C and a cone penetration according to BS2499-3 from 20 to 50 1/10 mm.
The In particular, the system according to the invention can comprising a primer which prior to introduction of the grout material, possibly also before introduction of the element, on the joint flanks and possibly distributed to the bottom of the grout. To a preferred To provide two-flanking liability takes place thereby however, an application of a primer, also known, is preferred as primer / adhesive, only on one or both joint flanks.
Especially Preferably, the element is designed as an extruded profile. It can the insert element as a solid profile, for example as a round profile, or but as an open profile, but more preferably as a hollow chamber profile, be educated. However, the present invention is covered Such embodiments in which the element in several sections is inserted into a joint. Especially is of the present invention also includes an embodiment the system such that in a joint spaced from each other Several elements are arranged so that one at least partially For water permeable joint closure available is provided.

It would be the element anyway have nature openings that a water passage in the direction of the gradient. The element However, it can also be designed in such a way that it is itself water-permeable is formed, in which case, for example, water over Pores and channels accommodated in the element could be derived in the direction of Fugengrund, so that a drainage of the road surface takes place. But Combinations of the aforementioned possibilities are also preferred.
In a preferred embodiment, the element lays at least partially on the joints flank. Preferably, a sealing contact takes place on the joint flanks. This can for example be made possible by the element, which is preferably flexible and elastic, for example, in such a dimensioning formed as a round profile in a joint and placed on the bottom of the joint, so that the element with its outer surfaces at the joint edges sealing applies, with quite a prior compression of the element can be done. The first, the casting material facing part of the element is preferably not only impermeable to the potting material, but also impermeable to water. The first part may also be formed, for example, in an embodiment of the element in the form of a round profile of an open-pore plastic by a placement of the element in a joint introduced blocking position, which can be introduced solid or liquid. Element and first part can thus be present in one or two parts and, if appropriate, be connected to one another, or else present separately from one another. When using a liquid coatable barrier layer, the potting material is then poured only after curing. An essential prerequisite when using a liquid barrier material, which forms the first, the casting material facing part, is that this at least not penetrate the element itself so strong that a water drainage would be prevented. Thus, the first part encompassed by the element may also be formed in two parts, in particular when the first part is designed as a barrier layer, for example in the form of a film or an inserted profile strip, for example double T-shaped in cross-section. Preferably, however, the first part is integrated into the element, and preferably at least partially in the main body thereof.

These and other advantages of the present invention will become apparent from the explained in more detail below. Show it:
1 a schematic cross section through the construction of a road surface;
2 : the detail I according to 1 in an enlarged view;
3 a first embodiment of the system according to the invention, arranged in a joint of a cover layer of a roadway; such as
4 A second embodiment of the system according to the invention.
First, it should be noted that the invention is not limited to the feature combinations shown in the figures. Rather, the features disclosed in the description including the description of the figures can be combined with those features indicated in the figures. In particular, the training of in the 3 and 4 shown two embodiments of the element, in particular its cross-section, not the only possible. The element can also be designed in any other way, as far as a first part is provided, which forms a barrier for a potting material, and thus the element allows a drainage of water. Finally, it should be noted that the reference numbers included in the claims in no way limit the scope of the present invention, but merely refer to the embodiments shown in the figures.
1 shows a cross section through the structure of an asphalt layer 2 with a cover layer 20 , a binder layer 6 and a base course 8th , wherein in the cover layer 20 a fugue 12 is arranged. Not shown in 1 is that the road surface 2 has a slope, which in particular the drainage of the road surface 2 serves. The joint 12 is between two adjacent sections of the cover layer 20 arranged. In particular, an open-pored asphalt can form the cover layer 20 be provided. Then is how 2 concerning the detail I can be seen, in particular in the upper region of the barrier layer, a barrier layer disposed above which in the direction of a slope of the road surface 2 Water W expires.
2 now shows the detail I according to 1 , wherein particularly well the arrangement of the barrier layer 4 in the upper area of the binder course 6 is apparent. Likewise 2 the basic structure of the fugue 12 with opposite joint flanks 14 and 16 and a joint bottom 18 being taken, being in the joint 12 an inventive system 10 , consisting of a solidified potting material 22 and the element 24 with a basic body 26 , is arranged.
3 shows in a cross section the joint 12 with a first embodiment of the system according to the invention 10 , which here is an already cured, waterproof potting material 22 , which connects to the upper part of the two cover layer sections 20.1 and 20.2 forms, which are permeable to water, as well as with an element 24 which has a trapezoidal base body as seen in cross-section 26 having, in a first, upper part 28 of the element 24 two investment elements 30.1 and 30.2 are arranged, which at the joint edges 14 and 16 lie sealingly. This will after setting the element 24 into the fugue 12 achieved that the filled cold or hot processable potting material 22 not in the lower part of the joint 12 and especially on the bottom of the grout 18 that would be a barrier to drainage. The first, upper part 28 of the element 24 is thus by the investment elements 30.1 and 30.2 as well as the top of the main body 26 , which faces the potting material formed. The top, possibly also reaching into a certain depth in the body 26 inside, is like the investment elements 30.1 and 30.2 for the potting material 22 impermeable. This can be achieved for example by impregnation with a bitumen material, which bituminous material will have other physicochemical properties than that bituminö se material, which may be in a hot workable grout 22 would be used. The rest of the body 26 is in the embodiment according to 3 permeable to water. In particular, the main body 26 of the element 24 made of an open-pore plastic or, for example, formed of a grid structure, in which water over side surfaces 34.1 respectively. 34.2 or over a floor 40 from the main body 26 of the element 24 exit or enter into this and can drain again. Optionally, in addition, in a lower part 36 of the element 24 , and preferably on the ground 40 of the basic body 26 , Installation elements 38.1 and 38.2 be arranged, by means of which a non-complete edition of the body 26 and thus the element 24 on the joint bottom 18 achieved. As a result, a water drainage in the area of the joint 12 further improved.
In particular, the investment elements 30.1 and 30.2 flexible and also articulated so far, as that they can be used even at lower joint widths, in which case the investment elements 30.1 and 30.2 a little further up on the joint flanks 14 respectively. 16 the fugue 12 can create, as by an arrow 32 indicated in 3 ,
In particular, the upper part 28 of the element 24 unlike the first, in the 3 embodiment shown also not integral with the main body or the contact elements 30.1 and 30.2 be connected. For example, the upper part 28 of the element 24 also represent an insert film, or be, for example, a thin extruded profile of a heat-resistant plastic material, which sealingly against the joint edges 14 and 16 the fugue 12 invests.
4 shows a second embodiment of the system according to the invention, wherein now the element 24 is designed as a round profile, and directly on the bottom of the joint 18 the fugue 12 is arranged. The element 24 is made for example of an open-cell plastic, which is permeable to water. The element 24 has a basic body 26 on which in an upper part 28 of the element 24 conditioning elements 30.1 respectively. 30.2 has, which sealingly against the joint edges 14 respectively. 16 invest. These investment elements 30.1 respectively. 30.2 However, could also be omitted, as far as the cross section selected by the expert of the element 14 this is sufficiently sealed to the joint edges 14 and 16 invests. In this embodiment, the element would then 24 from the main body 26 with a first, upper part 28 exist, with the upper part 28 for example, a body directly on the ground 26 may be applied protective layer which impermeable to potting material 22 is, and may for example be formed from a bituminous material. Conversely, however, the upper part 28 also be formed for example of a film, which is a leakage of the potting material 22 towards the bottom 18 to prevent.
With The present invention thus provides a system with which joints are closed in outer layers, in particular of open-pored asphalt can be without risking that due to of the material introduced into the joint makes it at least partially Interruption of the water flow along a slope a roadway comes, and thereby the drainage of a Cover layer is at least partially inhibited. The invention System is easy to lay, and consists at least of the potting material and the insert element, as far as this integrally connected thereto has the first, upper part, which for the potting material in Essentially impermeable. It should be at this point noted that essentially impermeable in the sense of the present invention means that potting material does not the insert element in its function as a means of conservation Dehydration in cover layers significantly affect can, that means always a water permeability is provided in the area of a joint. The invention However, the system can also continue, for example, a primer, especially for the potting compound and it can also be provided that the element is designed in several parts in that at least the first, upper part as a foil or otherwise formed as a trained protective layer or protective barrier which is not directly in particular with the main body the insert element is connected.
