Definitions

  • the invention relates to a method for the application of marking stripes in the form of material on a road surface, said marking material being ejected in a plastic state against the road surface from an apparatus which is advanced on the road surface, and wherein the marking material may consist of separate blobs which, when applied, form e.g. a road stripe.
  • step with the increased traffic and speed the need for draining of road surfaces as well as stripes is great, since it is hereby possible to avoid aquaplaning and in frosty weather icing.
  • the requirements with respect to the reflecting properties are great, since these must be visible in both directions of travel and reflect the light from the vehicles in a uniform manner.
  • this reflection must be effective, and to ensure this, the reflecting faces must protrude a suitable distance from the road surface in order for the desired reflection to be achieved.
  • the reason is particularly that the application takes place in such a manner that the material is deformed when it hits and adheres to the road surface. This is caused by the fact that the feed rate of the material is greater than the rate at which the material hits the road surface. Owing to this deformation, it is not possible to achieve a uniform transverse profile of the blob where it is applied in the form of pointwise located blobs.
  • the travelling speed of the application apparatus is therefore relatively low, viz. typically below 5 km/h.
  • This application rate of the pointwise blobs causes a disuniform reflection to be created.
  • the cross-sectional shape of the blobs will be such that the rearmost part of the blob will be raised, so that the reflecting faces are larger on the rear side of the blob than on the front side.
  • the object of the invention is to remedy these defects and drawbacks in a simple manner, and this is achieved according to the invention by a method wherein the blobs of material for forming the stripe are formed by a thermo- plastic material of a high viscosity at the moment of application, and immediately after the application to the road surface it is sprinkled with a granulate over the entire surface of the individual blobs of material, and the blobs of material and the granulate are ejected from the apparatus in a rearward direction and at a rate which corresponds to the travelling speed of the apparatus.
  • the draining properties are brought about by the high viscosity of the application material, which ensures an "open” surface so that the material is better able to absorb and drain off water.
  • the shape-forming properties are achieved in that the application takes place in such a manner that the material hits the road surface at a speed which is very low and preferably zero, whereby deformation can be avoided. This also applies to the subsequent application of the reflecting material, which will be distributed evenly across the entire surface of the profile.
  • the application rate may be increased con- siderably over the previous rate, that the draining as well as the reflecting properties are optimum, and that the reflecting effect is the same in both directions.
  • fig. 1 shows equipment for performing the method according to the invention
  • fig. 2 shows basic sketches of the various application means
  • fig. 3 shows the vectors of movement for a blob of material
  • fig. 4 shows an example of a stripe composed of blobs, seen from above.
  • the apparatus comprises a vehicle, a truck 1 , which is preferably provided with dual steering so that the vehicle may be steered at the selected side in both travelling directions.
  • this first application is a nozzle 2' which sprays a thermoplastic fluid primer 2 on to the road surface 12, which settles as a dense covering layer 5.
  • the actual marking material 3 is applied to this layer 5 via an ejector appliance 3'.
  • This appliance may consist of a rotating ejector having resilient ejector fingers for separate ejection of blobs of material 6.
  • the material consists of a likewise thermoplastic mass of high viscosity to form an "open" surface.
  • these blobs 6 may be provided with a reflecting, friction-imparting granulate 4, which is ejected from the rear appliance 4' so that it can ad- here firmly to the surface of the blobs 6 before these solidify.
  • Fig. 2 shows the three application stages in outline. All three stages are arranged such that the direction of application and the rate 10 for the individual materials 2, 3, 4 are rearwardly directed and opposite to the travelling direction and speed 9 of the vehicle 1.
  • the vectors 9 and 10 will neutralize each other, and the resulting vector 11 will therefore be a straight drop on the road surface 12.
  • the result of this method is that the application is controllable, thereby allowing a high-profiled material to be applied with a uniform and relatively high elevation on the road surface 12.
  • the blob 6 just ejected will be uniformly deformed to form a round raised blob having an evenly extending surface, which essentially forms a plane resultant stripe.
  • the method provides a considerably more traffic safe stripe, just as it may be applied at a relatively high travelling-application speed. Tests have shown that the application may be carried out at a speed of up to 45 km/h. This reduces the inconvenience to the traffic and the operators considerably.

Abstract

L'invention concerne un procédé d'application de bandes de marquage (8) dans lequel la bande est formée par des éléments sous forme de boulettes (3, 6), qui sont ultérieurement recouvertes de granulés réfléchissants (4) conférant une résistance de frottement. La matière est appliquée à une vitesse (10) correspondant à la vitesse de déplacement (9) d'un dispositif (1), et dans le sens opposé à la marche de celui-ci. Ce système assure une application complètement uniforme, car les boulettes (3, 6) ne sont pas déformées et les granulés (4) recouvrent la surface entière. La propriété réfléchissante est ainsi uniforme dans toutes les directions. Une couche primaire (5) peut éventuellement être appliquée sur la surface de la route (12) avant l'application de la matière.
