Lane marking.

The invention "relates to a road surface marking, for example, to identify pedestrian crossings, Traffic directions etc. is used.

Such markings are commonly applied to the road surface by one of two methods.

According to one method, a colored composition is painted directly on the road surface. the Markings produced in this way are quickly rubbed off by vehicles and pedestrians and must very often be replaced will. This is all the less desirable since the road marking by painting on or painting is a time-consuming one Operation is and requires a longer traffic redirection.

109887/0283

According to another "known method, the Markings made from ready-made marking sheets, which contain a grass fiber mat that is on top is coated or impregnated with a thermoplastic resin and on the underside with a "bituminous cement. When these marking sheets are applied to the road surface, they tend to ripple around the edges or roll up, causing them to detach from the road surface.

The invention relates to the second aforementioned road marking method and is directed to providing marking "sheets" which show no tendency to curl and solve.

The marking sheet according to the invention is characterized by a mat covered on the top with a colored resin composition and on the bottom with an adhesive Composition is soaked, wherein the mat extends at least on two opposite edges over the top and lower impregnation layers extends beyond, and the non-impregnated ends of the mat form tongues, which for this are intended to be glued to the road surface.

The application of the marking sheet according to the invention the road surface, for example on a! pedestrian crossing, happens quickly and does not make long interruptions of traffic required. The leaves are on the road surfaces applied in the desired form, and the tongues are glued flat to the street and aligned practically with this and so do not form a stepped obstacle for the arriving vehicles. This arrangement prevents a curling or curling of the leaves.

109887/0283

The adherence of the soil permeation layer of the leaf the road is caused by the passing traffic itself, because the vehicles can drive over the leaves immediately after these and the tongues hit the road surface have been applied. The pressure exerted by the vehicles not only causes the adhesive composition to adhere on the street, it also pushes some amount of this composition into the tongue areas, creating the connection consolidated between these and the road surface and the sheet is flattened.

If necessary, the marking sheet can be heated, for example by steam, before it is applied to the road surface is placed. This is particularly advisable in areas of cold elimas. Since the heating can be done quickly, it lengthens laying out the leaves is not essential.

The mat can be made of any material that has the necessary physical properties for impregnation with the Has resin and adhesive compositions and withstands the stresses caused by the traffic running on them will. The mat can therefore consist of synthetic or natural and of organic or mineral material.

Fiber mats made from any suitable synthetic or man-made fiber, such as polyamide fiber, zelwool-sisal fibers, cotton fibers, glass fibers, asbestos fibers and slag wool, are particularly suitable. These are only examples and mats made from many other types of fibers can be used. The packing density of the fibers in the mat is preferably such that the impervious mat has a density of 220 to 350 g / m ² .

The thickness of the sheets can vary depending on the intended use and Change composition of leaves. A suitable thickness is

109 887/02 83

"for example 1 to 3 mm.

According to a preferred feature of the invention the adhesive composition in the central area different than in the outer or "sealing" area, the adhesive being in the the latter area due to its different thickness and / or Composition flows more easily under pressure than the adhesive in the middle area. This causes a better flow of the glue off composition towards the tongues, reducing the sticking the tongues on the road surface is improved.

The outer sealing area or areas can be around the Run around the middle area or in the form of two edge strips, which are parallel to the tongues and to the middle area be used. In either case, the sealing area or areas can be narrower than that remaining area of the leaves. In principle, the sealing area can be produced as follows, for example:

(a) in that the sealing area is thicker than the central area is held. When the marking sheet is placed on the road surface and exposed to the pressure of traffic the sealing area absorbs most of the pressure at the beginning. It is flattened by on the one hand flows into the tongues, on the other hand, in the direction of the central area until it is flush with it. From there on comes the middle range in close contact with and adheres to the road surface;

(b) in that the sealing area is composed of a composition which differs from that of the central area and is more easily flowing than that latter. For example, the sealing area can consist of a

1098 8 7/0283

Composition "consist" which has a "bituminous material, the ring-and-ball test result (ring-and-ball test) according to ASiDM D36-26 preferably in the range from 60" to 10O ⁰ C, while the middle range consists of a composition may be prepared which comprises a bituminous material, the ring and ball according to ASTM D36-26 Iestergebnis preferably in the range of 100 "is up to 140 ⁰ C. When both the sealing portion and the central portion having compositions containing resin material, the melting point may be of the resin material of the seal "area" for example, 40 "to 60 ⁰ C and the resin material of the central region preferably 60" to 100 ⁰ C ".

The life of road markings made with the inventive Marking sheets have been produced, is about 5 times the markings according to the test results, made with conventional marking sheets.

In the following, for example, preferred embodiments of the invention are explained in more detail with reference to the accompanying drawings.

Pig. 1 shows a partial vertical section through a marking sheet according to the invention, which is laid on a road has been but not yet adhered to it, i.e. during the beginning of the marking process;

Pig. Figure 2 similarly shows the same sheet at the end of the marking process;

Pig. Fig. 3 is a bottom plan view of a sheet of the present invention showing the adhesive composition in sealant and. Central area is divided.

The marking sheet of the invention, which is included in the Pig. 1 and 2 is shown, includes a fiberglass mat 1, which is on the

109887/0283

Top with a colored, weather and abrasion resistant resin composition 2 and is soaked on the underside with a bituminous adhesive composition 3. The two compositions meet within the mat and form cover layers on its surfaces. Layers 2 and 3 extend essentially the same distance and not as far as the longitudinal edge, on each of which an edge strip of the mat to form a tongue 4 remains free. When the sheet is placed on the road surface, the tongue 4 turns down bent on the road surface, as shown in Fig. 2, and adhered to this with the aid of an adhesive. Of the Glue can be applied either to the tongues in the course of making the strip or when applying the sheet to the Street 5.

As soon as the leaves have been put on the street in this way, the traffic is released again. When the vehicles Rolling over the sheets causes the pressure generated by the adhesive composition 3 in the direction of the tongues 4 flows, and that the tongues are pressed onto the road surface. So the tongue 4 is firmly attached to the Road surface connected. At the same time, the colored, upper layer 2 flows in the direction of the tongues 4, so that the step-shaped transition between the tongues and the soaked main part of the sheet is flattened to a sloping edge will.

In the embodiment of FIG. 3, the central area is 6 the adhesive composition is limited by two sealing areas 7 on two sides which are parallel to the tongues 8 and are thicker than the central region 6 so that they form downwardly projecting ribs. The material of the sealing areas 7 is also a bituminous or resinous adhesive, but it is softer and has better fluid properties.

109887/0283

shafts as the material of the center area, so that the Flow of the material in the direction of the tongues 8 is facilitated.

The invention is to be explained in more detail below with the aid of examples which represent a limitation. the percentages given are $ by weight. In the examples the abbreviation R & K for ring-and-ball £ ests accordingly ASTM D36-26 used.

Example 4 Manufacture of a marking sheet

In making the sheet, a colored composition, for example any of the compositions described in Example 1, is applied to one surface of a mineral fiber mat, for example by spraying or spreading. This process is repeated or continued until the desired thickness is achieved.

An adhesive composition is then sprayed on or spread on the other surface of the mat. When the applied adhesive composition is in a seal

109887 / Q283

processing and a central area of different composition is divided, the spraying or distributing process can be in two successive stages with the help of templates. If the sealing areas protrude and have the same composition like the middle area will have the adhesive composition initially with a uniform thickness over the entire area applied, and then the sealing area is produced by adding a further amount of the same adhesive, preferably with With the help of stencils.

After soaking, the sheet is dried and then ready for use.
