"Material for markings on road surfaces"

The invention relates generally to road markings, which is provided on egg surface of the otraßendeoke itself are. The term "road surface" is understood to mean each surface over which vehicles drive, ie for example the surface of busy roads and highways, of 2nd order roads, squares etc /.

In particular, the invention relates to the production and use of materials for marking overhead surfaces, those to limit una regulation of traffic (for example to subdivide the surface into different Roadways, apuren, etc.) are used, whereby the materials (are made in such a way that they have a high degree of visibility exhibit.

Lieit driving exists and develops more and more the There is a tendency to use the system of dykes (strips, etc.) Like.) by applying paints to the road surface to replace with the ijysttia, where on the same surface optionally prefabricated, tape-shaped materials are applied, the underside of which by. Practice Ank.1 at the

'' Straijenfläche is attached and the top of which forms the marking. Painting the marking has numerous disadvantages, such as the time it takes for the paint to dry. Such a disadvantage can only be partially excluded, for example in the manner described in the ULLi-i-atentschrii't 1 89 5 045. In addition, the markings produced by painting have a low durability and are quickly peeled off when vehicles drive over them. The use of flexible sheet material to make marking devices offers numerous advantages. An example of this type has become known from UüA-ratentschrift 2 503. In the ViiA-ta tentschrift 2 898 825 an example is described in which the road surface is pretreated and means for protecting the applied strip are provided.

Such tape-shaped materials for road markings can be applied with the aid of mechanical devices which move at high speed over the road and can produce both continuous and interrupted markings, ie a series of short, lined strips which are spaced apart. An example of such means is from the USA Jfat ent magazine produced 3,007,838.

These band-shaped materials have some disadvantages for Jedooh on. Your visibility iot the greater, yes smoother it are. However, this makes their surface slippery, especially

a material with a rougher surface, on the other hand, holds the dirt and is therefore difficult to see. A serious problem with these materials is their poor visibility at night in unlit streets, ie if the marking material is illuminated only by the headlights of vehicles. It is important that the mark is visible over long distances clearly even and especially when visibility is poor, such as in the case of to oncoming vehicles, etc. because the light intensity decreases (Dimming) and at the same time dazzling from the headlights of the oncoming motor vehicle. In other words, the markings should be such that they are visible to those who see them at a very small angle of incidence (i.e. for the driver of a motor vehicle who see the Markings from a few tens of sts etern and must see clearly from a distance of several hundred meters) can be clearly seen if they are illuminated by light incident at a very small angle (ie from the light of the vehicle's headlights).

It has already been proposed to provide lacquers on the surface of markings intended for the production of markings, and in particular in thin glass beads, which are preferably treated so that each surface bead forms a reflective or retroreflective means which allows the light to be incident at virtually any angle reflected.

In Pig. 1 is the surface 10 of the ceiling of a road 11, for example with a continuous marking strip 1 Mistake. Such a marking strip can also be interrupted or be double. The road can also have several marking strips, which serve, for example, to subdivide them into lanes, or other horizontal markings, for example Pedestrian crossings, stop lines and the like. Suitable for these and all other marking forms or types the marking strip 12, which is described below will.

The marker strip 12 is both in daylight even if there is lighting from one provided above the street Light source, for example a street lamp 13, is very good visible.

In contrast, the visibility is significantly poorer if the road is ^{illuminated exclusively by the headlights of motor vehicles A f} , A ". In this case, the surface of the marking strip 12 is illuminated by light that is at a very small angle of less than 5 ° from a Distance from which the marking must be clearly visible.

In Pig. 1 Bind shows the most unfavorable conditions, namely the two motor vehicles come towards each other, whereby on the one hand the strength of the headlights is reduced (dimmed) and on the other hand an unavoidable partial glare occurs.

Like from Pig. 2 , a part of the surface of the marking strip 1 2 consists of the upper surface of one

P The inserts consist of a suitable composition, the perceptible amounts of reflective rigniente or also contains glass beads or spheres.,

Measurements were made by projecting a bundle of light with fullelized rays (in accordance with lighting conditions bui distances) from a glLthiadenxiain _F e, as is usually used in motor vehicle headlights, at different angles of incidence jilpha (i'ig. 2) and the reflected uicht under The same angle was captured and measured by means of a photoelectric sensor that responds in every visibility range.

^ ¹ Ig. 4A, 4B, 4C and 4D show very characteristic conditions which are suitable for light measurements. According to iig. 4A, an insert 14a is illuminated which is in the optimal state, the land 16a being smooth and precisely bevelled. The iiana 16 b of the insert 14b in Fig. 4B has a slope of about 45, which is based on heavy wear,

For control and comparison, ig. 40, the square hand 16c of which is covered with a light-absorbing black compound, and in the case of the i insert piece I4d of X ¹¹ Ig. 4D with the light-absorbing black joint provided on the upper side and the inclined side 16d lying in front, measurements were made.

The diagram according to I ¹ Ig. Figure 3 shows curves A, B, 0 and D obtained using these different inserts. The curve A shows that the marking material reflects best when it is illuminated from above, whereby it is more than 6C; ' dos the incident light, and that it ensures an extremely strong iteflexion (more than 90 '/ O) when the input

Even if the edge of the insert (fig. 4B and curve B) is heavily worn, the light reflection remains at small -ünfallwinkυΐη over 50 ^, and in a certain sense it becomes a Improvement of the overall effect achieved,

The importance of the flexion capacity of the edges of the inserts emerges from the xvurve G. In this case it is closed See that the reflection is extremely small and practically equal to Hull becomes when the angles of incidence are small even when the upper one

■ The area of the 3 insert stacks is exposed and remains in operation. As far as the effects are concerned, this! 'All corresponds to the l-all, in which the marking strip has a flat surface and its composition contains pearls or spheres. In such a case, the extremely low reflective capacity of the strip at small angles of incidence is only partially compensated for by the large width of the reflective surface.

There were various dimensional relationships and Relationship between the inserts and the total surface the marking strip, its thickness and other parameters, Determine the total cost of the marking material that mechanical resistance and wear resistance and the rigidity effects based on the fact that the Einoatzstück protrude, fixed. The results of these experiments can be seen from Table 1, in which the numerical values are given in millimeters.

To produce the marking material, in principle the techniques well known in the art are used. For making the body 15 of the marker strip compositions based on natural or synthetic rubber (G), which possibly binders (L), fillers (C) and whitening agents (i) are added. The fillers and the whitening agents can be made from consist of a single component that has the same function «The composition can preferably be stabilized Ren (S), optical stabilizers, coagulants, etc. can be added.

The insert pieces 14 can consist of the same or a similar one Composition exist, with additional optically reflective and refractive substances (Ct) as well as splinters or particles made of aluminum or other highly reflective materials are provided in order to achieve the desired light reflection effect Achieve, with the pearls at the same time as very small capacitors serve that ensure the refraction effect.

Preferably compositions are used that are vulcanizable and / or are polymerizable and / or can be arranged in a network. They are therefore also vulcanizing (V), activating (A), network-like arranging (R), copolymerizing (Cp) components and optionally flux (F) on.

The anchoring and fastening of the insert pieces in the marking strip is preferably carried out by means of suitable adhesives made which are suitable for the compositions of the parts to be joined, with suitable plasticizers (P),

109847/0079

Solvent (solution) and diluent (thinner) are added. The connection between the lens pieces 14 and the .body 15 of the marking strip can by mechanical Means are completed, for example, in that the Ein; .atzteile used dovetail-shaped in the body are.

The following tables are examples of compositions listed for the manufacture of the body 15, the Eincatzütacke 14, suitable adhesive for connecting the üin- Set pieces to bind with the body and finally by glue suitable for attaching the body of the marker strip on the bitumen surface of the street.
