Definitions

  • the invention relates to a surface covering adapted for application on surfaces, such as road surfaces, side walk surfaces, foot and bicycle way surfaces, playground surfaces, parking lot surfaces, parking house floor surfaces, or sports ground surfaces, the covering comprising a thermoplastic sheet.
  • the invention also relates to a method for application of a surface covering to a surface, such as road surfaces, side walk surfaces, foot and bicycle way surfaces, playground surfaces, parking lot surfaces, parking house floor surfaces, or sports ground surfaces.
  • the invention also relates to a kit of parts for application of a surface covering on surfaces, such as road surfaces, side walk surfaces, foot and bicycle way surfaces, playground surfaces, parking lot surfaces, parking house floor surfaces, or sports ground surface.
  • thermoplastic markings having the shape of the total intended marking or having the shape of a part of the intended marking.
  • Such pre-manufactured thermoplastic markings may e.g. be adapted to be placed on road surfaces or the like and then be subjected to heat, e.g. by the use of a blow torch, until it reaches an almost liquefied state sufficient for it to adhere to the road surface.
  • Pre-manufactured thermoplastic markings are e.g. known from GB-A-2 030 586 , SE-B-399 575 , SE-B-341 873 , and US-4 708 518 .
  • thermoplastic markings with so-called temperature indicators, e.g. by providing colour changing indicators or by providing deformations in the surface of the pre-manufactured thermoplastic markings by scoring or punching.
  • a pre-manufactured thermoplastic marking is e.g. known from EP 0 882 159 B1 , in which it is disclosed to provide deformations on the upper surface of the pre-formed thermoplastic marking.
  • the temperature indicators are intended to indicate to the road worker when the pre-formed thermoplastic marking has been heated sufficiently to adhere to intended extent to the road surface.

  • the indicator By providing an indicator at the intended lower surface and by choosing the materials such that the indicator has a density lower than the density of the thermoplastic sheet, the indicator will, in response to the thermoplastic sheet being heated to an at least partly molten state, rise through the thermoplastic sheet and form a visible indication. By providing the indicator at the intended lower surface of the thermoplastic sheet, the indicator will thereby indicate that the intended lower surface actually has reached the intended temperature, or otherwise the indicator would still be stuck in the thermoplastic material.
  • the thermoplastic sheet may be basically any kind of thermoplastic material suitable for use as surface coverings adapted for application on road surfaces, side walk surfaces, foot and bicycle way surfaces, playground surfaces, parking lot surfaces, parking house floor surfaces, or sports ground surfaces.
  • the thermoplastic material is preferably chosen from the group consisting of thermoplastic resins and thermoplastic polymers. Such materials are suitable for mixing with filler and pigments to provide a wear resistant road marking.

  • the thermoplastic sheet may be formed e.g. from so-called C5 based, C9 based and alkyd based thermoplastic materials.
  • the polymers may e.g. be EVA or SIS.
  • the indicators may provide a visible indication by having a shape providing contrast to the upper surface of the thermoplastic sheet. This may e.g. be accomplished by the indicator being formed of bodies rising through the thermoplastic sheet. Examples of such bodies are e.g. solid or hollow glass beads having a density lower than the density of the thermoplastic sheet. Such indicators may be arranged to be worn off for example by applying active wear on the surface covering, or by normal wear after a short period of time relative to the lifetime of the surface covering.

  • the low density indicator need not be provided alone on the intended lower side of the thermoplastic sheet; the low density indicator may be mixed with or mixed into other substances. Such other substances may be provided for facilitating the rise and/or for other purposes.
  • the rise of low density bodies may e.g. be facilitated by mixing them into a low density wax that melts and facilitates the rise of the bodies through the thermoplastic sheet.
  • a wax may be transparent or may be pigmented to provide a contrast in itself.
  • the piece of material at the intended lower side of the thermoplastic sheet has a low density.
  • the low density indicator may be mixed into or mixed with heavy materials serving other purposes as long as the low density indicators are released and allowed to rise through the thermoplastic sheet when the thermoplastic sheet is subjected to the above mentioned heating.
  • a low density indicator in the form of low density bodies, such as glass beads, may be mixed into a heavy substance, where the heavy substance is adapted to melt and release the low density indicators.
  • a low density indicator in the form of a low density material melting and rising through the thermoplastic sheet may e.g. be mixed with heavy particles, which particles will be left behind when the low density melting material, such as wax and pigments, rise as a low density indicator through the thermoplastic sheet.
  • the indicator may comprise pigment providing contrast between the indicator and the thermoplastic sheet.
  • the use of a pigment is a robust manner of providing a distinct contrast that is clearly visible to the user.
  • the pigment may have colour contrasting to the colour of the thermoplastic sheet.
  • the contrast may be in the form of the pigment having a different gloss.
  • the pigment may e.g. be ultramarine blue.
  • the pigment may be an integral part of the indicator.
  • the indicator further may comprise a carrier substance mixed with the pigment.
  • the carrier substance may be a wax, resin, oil, lubricant and/or polymer.
  • the indicator may comprise, preferably as a major constituent comprises, a material having a melting temperature within a temperature range reached by the indicator during application of heat to the surface covering for attachment of the surface covering to the surfaces.

  • Such melting may be used to facilitate the indicator rising through the thermoplastic sheet.
  • the thermoplastic sheet may e.g. have a melting temperature that is slightly higher than a melting temperature of the above mentioned material of the indicator. With such a choice of melting temperatures, the indicator will melt shortly before the thermoplastic sheet reaches its melting temperature and as soon as the thermoplastic sheet reaches an at least partly molten state, the indicator may rise through the thermoplastic sheet.
  • thermoplastic sheet may e.g. have a melting temperature slightly lower than the melting temperature of the indicator. This may be used to provide small indicators rising through the thermoplastic sheet as bodies and which indicators then melts and flows out and forms a relatively large spot of contrasting colour on the upper surface of the thermoplastic sheet.
  • the material of the indicator may be a carrier substance or a material forming an indicator body.
  • the material with the melting temperature may e.g. be a glass material or plastic material out of which beads may be formed. Such indicators maintain its shape to a certain temperature threshold.

  • the indicator, the carrier substance and/or the pigment may be non heat resistant at a temperature threshold being slightly greater than the melting temperature of the thermoplastic sheet.
  • This may be used to secure that the thermoplastic sheet has reached the desired molten state before the indicator starts to disappear.
  • the visibility will be reduced.
  • the visibility will be reduced with increased strength of the exposure, such as higher temperature, and/or with increased exposure time.
  • Less visibility in respect of pigments may be referred to as providing a Michelson contrast being less than
  • the Michelson contrast is calculated by the formula (L1-L2)/(L1+L2), where L1 is the luminescence of the indicator when the indicators have risen through the thermoplastic sheet and L2 is the luminescence of the indicator when has been rendered less visible.
