Definitions

  • the invention is concerned with a surfacing that is fluorescent in ultraviolet light.
  • the invention is concerned with a binder for asphalt or other surfacing, made from material that is fluorescent in ultraviolet radiation.
  • Asphalt, chip coating, slurry seal or other bituminous coats which as an abrasion resistant component contain stone material, generally filling powder, sand or gravel and binder component, generally bitumen from crude oil that contains high molecular paraffinic, naphtenic and aromatic hydrogen carbons.
  • the visibility can be improved to a given amount by choosing light stone material for the asphalt but it does not eliminate the problem with the visi ⁇ bility.
  • the solution to this problem as suggested by SE-462 109 is to illuminate the surface of the road surface by ultraviolet light that in the above conditions is absorbed better than visible light through the air that contains water drops and by making the road coating fluorescent in the above mentioned UV-radiation by adding mineral which is fluorescent in UV-light as a filler to the asphalt, whereat the road and changes in the road and objects on it are clearer distinguished for an observer.
  • the field of vision of the chauffeur is improved with having UV-light lamps in the cars so that the opposite traffic does not become dazzled.
  • the object of this invention is a fluorescent coating that is better than previous coatings.
  • the coating of the invention is mainly characterized in that the binder contains hydrogencarbon component that is fluorescent in ultraviolet light.
  • a crude oil fraction that is fluorescent in UV-light is chosen for the binder of the asphalt such a coating can be achieved for the street, road and the like that is distinguishable, being fluor ⁇ escent even in bad conditions.
  • a crude oil fraction contains fluorescent compounds which typically are aromatic compounds.
  • the asphaltenes damp the fluorescence why big amounts of them should not be used or most preferably no such materials should be used at all.
  • Bitumens that are used as binder for asphalt always contain asphaltenes and thus they are not fluorescent materials.
  • the distillation range of a fluorescent oil fraction suitable for use as a binder typically begins at ca 350°C and does not essentially contain asphaltenes, which remain in the distillation rest. The distillation range can begin at 300°C and even at a lower temperature but the effect of these fractions in view of the binder properties are harmful and neither do they help in strengthening the fluor ⁇ escence.
  • the quality of the asphalt or the coating of the invention is similar to conven ⁇ tional asphalt coatings why similar spreading and other treating devices can be used.
  • a fluorescent oil fraction is too light for use as asphalt or surfacing why its binder properties are weak.
  • the binder properties can be improved by adding different rubbers, polymers or resins in the fluorescent oil. Solutions and emul- sions can be prepared from the fluorescent binder in the same way as from bitumen products.
  • the fluorescent layer is not necessary thick, therefore a very thin layer is enough in view of the fluorescence.
  • Thin coatings can be used as fluorescent layers and in extreme cases a mere spreading of a fluorescent oil fraction, by for example spraying, is enough to the existing road surface or a corresponding surface, which is wished to make visible in UV-light.
  • An asphalt binder was prepared by mixing in one hour at the temperature of 150°C, 70% tall-oil resin with 30% of the heaviest distillation fraction from a vacuum distillation, the viscosity of which in 50°C was 85 mm /s and the distillation range of which began from 380°C according to the method of ASTM D 1160 and the asphaltene content of which was below 0,5% according to the method IP 143.
  • the softening point of the prepared binder was 48,5°C defined with the method of ASTM D 36 and the penetration in 25°C was 34 1/10 mm defined with the method of ASTM D 5.
  • the binder gave a white fluorescence when observed in dark with UV-light, the wave length of which was 360 nm.
  • SUBSTITUTE SHEET made with the above mentioned binder.
  • the binder content was 5,7 % of weight.
  • the asphalt gave a white fluorescence when observed in dark with UV-light when the corresponding mass AB20/IV used as a comparison made of conven ⁇ tional bitumen B120 was completely dark.
  • a binder for asphalt was prepared by mixing 90% of an oil fraction used in Example 1 and 10% SBS-rubber Finaprene 416 in a temperature of 180°C during two hours.
  • the softening point of the prepared binder was 41°C (ASTM D 5).
  • the binder and the AB20/IV asphalt mixture made with this binder gave a white fluorescence by observing in dark with UV-light with a wave length of 360 nm.
  • a water emulsion was prepared from the binder used in Example 1 by using diamine-hydrogen chloride acid-mixture as emulgator.
  • the binder content of the emulsion was 62%.
  • the emulsion was used to prepare a chip coating SIP 4-8 according to the Finnish Asphalt Norms 1987.
  • a white fluorescence was achieved in the prepared chip coating by observing in dark with UV-light with the vawe length of 360 nm.
  • a corresponding chip coating made by a commercially avail ⁇ able bitumen based chip coating emulsion BIE-1-SIP (Neste Oy) was not fluorescent in UV-light.

Abstract

Asphalte ou autre revêtement contenant du bitume à titre de liant. On peut le rendre visible lorsqu'il est éclairé par des radiations ultraviolettes en y ajoutant un constituant huileux fluorescent à la lumière U.V. que l'on obtient par exemple par la distillation du pétrole. Afin d'améliorer les caractéristiques du liant, on peut ajouter au constituant huileux diverses matières macromoléculaires naturelles et synthétiques.
