Definitions

  • the invention relates to a method for producing or tracing a horizontal marking on roads, in particular boundary, guiding and warning lines, according to the preamble of claim 1, and also to a horizontal marking produced by this method.
  • Thin-film markings the solids of which are dissolved in a solvent for application, are known (for example "Handbook for Marking Streets", edited by Schönborn and Domhan, Otto Elsner Verlagsgesellschaft, Darmstadt, 1981). After spraying, these marking compounds dry and harden only in the case of one-component paints by evaporation of the solvent or, in the case of multi-component paints, by evaporation of the solvent and by chemical drying.
  • these marking colors are applied with only a relatively small layer thickness, namely with a wet film thickness between a minimum of approximately 0.35 mm and a maximum of approximately 1.5 mm, which means dry film thicknesses of approximately 0.2 mm to approximately Corresponds to 1.0 mm.
  • glass beads with a refractive index of 1.90 to 1.95 are currently available on the market, which are offered by Potters-Ballotini GmbH. Because of their high specific weight, however, such glass beads tend to sink largely into the freshly applied marking. While the general night visibility on dry roads can be improved by the measures mentioned above, achieving good night visibility when wet is a problem which has not yet been solved satisfactorily.
  • the retroreflection of road markings which is partially or completely covered by a film of water in the dark and wet are more or less greatly reduced or practically no longer available, because the headlight light emanating from a vehicle is largely or completely reflecting on the water surface, instead of being retroreflected towards the driver of the vehicle.
  • the visibility of the road markings, especially the boundary lines for the road or lane, as well as the guidance or warning lines is particularly important.
  • the invention has for its object to provide a combination of features and process steps known per se, a thin-layer road marking, which has a surprisingly good night visibility when wet and which can be produced with little effort and rationally and in particular also easily re-marked and maintained can be.
  • the present invention also relates to a road marking produced by this method.
  • the typical property, known per se, of a solvent-containing thin-film marking namely the property that such a marking no longer sticks for a period after the point in time at which it can be driven over, i.e. when it is passed over smeared, can be permanently deformed by a suitably dimensioned pressure.
  • the drying time which determines the time of passability, is generally between 15 minutes and one hour; It generally takes several hours to fully cure, after which practically no permanent deformation is possible.
  • this one-component marking compound contains a binder based on polyvinyl, a highly polymeric plasticizer that has a long-lasting plasticizing effect, ketone resins, fillers in the form of carbonates and silicates as well as ketones and aromatics as solvents.
  • the distance between successive elevations of the surface profile is large enough, for example between 10 and 30 cm, then surface profiles with a profile height that is greater than the dry film thickness can be produced.
  • the raised linear profiles can rise above the level of the remaining mark by 0.8 to 1.0 mm and in the case of larger dry film thicknesses by 1.0 to 2.0 mm.
  • the method according to the invention is particularly interesting in the aftermarking of worn-out color lines if the marking compound used, as in the case of the already mentioned Plastiroute marking products and also other commercially available marking compounds, contains a binder, the hardening of which is reversible, so that the old hard color trace on its surface becomes soft and deformable again through the action of the solvent of the freshly drawn marking.
  • the marking compound used contains a binder, the hardening of which is reversible, so that the old hard color trace on its surface becomes soft and deformable again through the action of the solvent of the freshly drawn marking.
  • profile heights of up to approximately 2.5 mm can be produced.
  • Thin-film markings generally have a drying time of 20 to 40 minutes, with very large wet film thicknesses of 1.0 to 1.5 mm also up to 60 minutes, and only fully harden after a few hours. Therefore, in the production of profiled markings, there is sufficient time to first preferably mark a long distance of, for example, 5 to 8 kilometers in one operation and to coat with glass beads, which takes about 1 hour at marking speeds of generally 5 to 8 km / h , and only then to provide the entire long, newly drawn marking section with a surface profile in a further continuous work step, for which purpose a suitable vehicle is preferably used, the wheel of which rolls on the marking with its appropriately profiled rubber tire.
  • the maximum possible profiling speed of generally 10 to 30 km / h can be driven.
  • This possibility of marking comparatively long road sections in one continuous operation and then in a further continuous operation profiling allows the required work to be carried out quickly and efficiently.
  • the method according to the invention is intended in particular to produce lane boundary lines on motorways and other highways, because the boundary lines, the good recognition of which is particularly important at night and in the wet, are outside the lane and are therefore usually wet and covered with water for longer periods of time.
  • the method according to the invention can also be used to produce center lines or guideline and warning lines.
  • a marking line 2 in the form of a thin-layer marking is first drawn in a known manner from a solvent-containing marking compound on the road surface 1, which is done by means of a Marking vehicle installed spray gun using compressed air or, if necessary, by means of a spray can attached to a hand-held marking vehicle and containing the marking compound.
  • a Marking vehicle installed spray gun using compressed air or, if necessary, by means of a spray can attached to a hand-held marking vehicle and containing the marking compound.
  • the proportion of glass beads with a high refractive index which can generally be between about 1.9 and 2.0, is expediently between 301 and 70%, preferably about 50 /, and is chosen according to the respective conditions or wishes.
  • glass beads with high refraction can be used; however, since these are more expensive than normal refractive glass beads, a mixture is less expensive, and in general such a mixture of high and normal refractive glass beads also provides a surprising improvement in retroreflection.
  • the marking compound is applied, for example, with a wet film thickness of 0.6 mm, which results in a dry film thickness of, for example, 0.38 mm after drying, that is to say after the solvent has evaporated.
  • the drying time, after which the marking can be passed without the risk of damage or smearing, when using a marking compound known under the trade name Plastiroute, if the air humidity is not too high, is between 20 and 30 minutes.
  • the marking compound remains plastically deformable from the point at which it can be driven on until it has fully hardened. Only after complete hardening, up to which a time span of several hours, in particular three to five hours, can the marking practically no longer be deformed.
  • the surface of the marking line 2 is then profiled in the desired manner after the drying time has elapsed and before it has fully cured, starting at the earliest about 30 minutes after application.
  • the surface profile consists of linear elevations 3 which run obliquely to the roadway and which have an approximately trapezoidal cross-section which tapers upwards and have an average width of about 1 to 3 mm and are at a distance of about 20 cm from one another.
  • a vehicle with a correspondingly profiled rubber tire 4 can preferably be used to produce this profiling are on the tread the grooves 3 corresponding to the ridges 3 are provided and which can be rolled while driving on the marking line 2.
  • the contact pressure of the tire or the vehicle weight acting on the wheel axle in question must be dimensioned accordingly.
  • the deformable marking compound is advanced with the formation of an increasing undulating elevation until it is covered by the following groove 5 and is therefore pressed into it.
  • this is Profile height that is the height of the profile elevation 3, which is above the level of the other marking line 2, approximately 0.8 mm to 1 mm.
  • Triangular or arc-shaped profiles can also be selected, it is important to create profile surface sections that are as steep as possible, preferably approximately perpendicular to the incident headlight, so that due to the low or vanishing angle of incidence, the normal specular reflection also contributes to retroreflection.
  • the glass beads are pressed a little into the marking compound by the subsequent rolling over with the rubber tire, so that they adhere well to it.
  • the subsequent complete hardening there is still a slight shrinkage of the marking compound in such a way that at least some of the beads on the surface increase the size of the protruding segment somewhat.
  • the glass beads located on the steep surface section of the elevations 3 facing an incoming vehicle are also, due to this position, fairly protected from excessive stress, which could tear them out of the marking mass, so that the retroreflectivity, which is optimal due to the favorable angle of incidence, has a steep orientation
  • Surface sections has a long service life.
  • the wet film thickness of thin Layer markings which are suitable for producing profiled marking lines according to the invention are between approximately 0.35 mm and 1.5 mm, which corresponds to dry film thicknesses of approximately 0.2 mm to 1.0 mm.
  • the profile heights that can be achieved when drawing a new color trace for the first time can be between approximately 0.5 and 2.0 mm, preferably between 0.8 and 1.5 mm.
  • profile heights between about 0.5 and 3.0 mm, preferably between 1.0 and 2.0 mm can be produced. If the old color line to be renewed, which in turn can of course have already been renewed one or more times, has a dry film thickness of approximately 1 mm and the dry film thickness of the newly applied marking line is approximately 0.4 mm, then profile heights can easily be achieved Shape approximately 2 mm to 2.5 mm.
  • the invention is not restricted to the exemplary embodiment described, but rather allows for numerous variants with regard to the shape and the geometry of the surface profiles produced and the type of their production.
  • Various such surface profiles and devices for their production are the same in DE-OS 1 534 209 Described by the applicant.
  • the distances between the elevations 3 according to FIGS. 1 and 2 can be chosen as desired, preferably between 10 and 30 cm, and the cross sections and the widths of the raised profile areas can also be different.
  • the surface profile can consist of alternating raised and recessed areas with approximately the same dimensions in the direction of travel. If necessary, depressions can also be pressed into the marking line at greater distances, the cross-sectional width of which is smaller than the distance between successive depressions. All of these possible surface profiles can be easily created with a correspondingly profiled car tire.
  • the surface profiling is preferably selected such that as many surface areas as possible are at least approximately perpendicular to the direction of incidence of the headlight light and are already irradiated from a greater distance therefrom and that the water can run off well between the elevations; As far as possible, no water should be able to accumulate on the elevations, so that these elevations should expediently be sufficiently narrow and their mean widths should not exceed a maximum of 10 mm, preferably 1 mm to 5 mm.
