Definitions

  • the present invention relates to a method of repairing a road surface with longitudinal depressions in the shape of wheel tracks.
  • the invention also concerns a road surface with a wheel track repaired and filled according to the method.
  • SD Surface dressing
  • bituminous binder cutback or bitumen emulsion
  • stone materials having well-defined particle size or size fractions in one or more layers. The more layers of stone, the greater the amount of binder to be sprayed.
  • the object of the invention is to provide a method for repairing wheel tracks on road surfaces whereby significantly deeper wheel tracks can be repaired as compared with the prior art. Furthermore it is the purpose to provide a road surface with a wheel track repaired and filled by the inventive method and by which a more even road surface is achieved after the repair work.
  • particle size fraction is meant the particle sizes within a certain range provided by screening the stone material.
  • the invention provides that it becomes possible to repair appreciably deeper wheel tracks that hitherto possible by the prior art, and that a more even road surface is achieved.
  • more binder can be applied at the points where the wheel track is deepest, and less binder can be applied at the edges of the track (which are not so deep).
  • Relatively large stones are laid at the bottom of the wheel track after which spraying is performed at a width corresponding to the total width of the wheel track. Then a layer of smaller stones is laid in the whole width of the track.
  • a Sandwich-SD is provided at the bottom of the wheel track and a 1 SD at the edge.
  • the laying of two layers of stone where the tracks are deepest requires a larger dose of binder which is provided by programming the existing spraying equipment.
  • possible cracks at the bottom of the wheel tracks are closed effectively, and an enhancement of the load capacity of the road is indirectly achieved thereby.
  • the method is cheap to perform, among others because it implies a much reduced consumption of material as compared with milling/cutting up and laying of hot asphalt.
  • the extent of the repair work which is limited to the wheel track itself, means minimal inconvenience to the traffic.
  • bituminous binder e.g. cutback or bitumen emulsion
  • the peculiar feature of the road surface with wheel track repaired according to the invention is that the wheel track is filled with a first layer of stone material with predetermined particle size or particle size fraction at the bottom of the wheel track, that the amount of binder per area unit sprayed or laid in the deepest area of the cross-section of the wheel track is greater than the amount of binder sprayed or laid close to or at the edges of the wheel track, and that a second layer of stone material with predetermined particle size or particle size fraction which is substantially smaller than the particle size or fraction in the first layer is laid upon the first layer of stone material and the binder at least in the entire width of the wheel track.
  • the amount of binder per area unit sprayed on the area of the cross-section of the wheel track where the track is deepest is between 35% and 50% greater than the amount per area unit sprayed on the area of the cross-section of the wheel track which is at or close to the edges of the wheel track.
  • the particle size fraction in the first layer of stone material may overlap the particle size fraction in the second layer of stone material with up to 75%.
  • the particles sizes in the two layers of stone material may be discrete and such that the particle size in the first layer of stone material is up to five times greater than the particle size in the second layer of stone material.
  • the amount of stone material or aggregate laid in the first layer of stone material is in the range 8 to 30 kg/m 2 . Furthermore, it is preferred that the amount of stone material or aggregate in the second layer of stone material is in the range 10 to 17 kg/m 2 .
  • the amount of binder per area unit sprayed close to or at the edges of the wheel track is in the range 0.5 to 2.0 kg/m 2
  • the amount of binder per area unit sprayed on the bottom of the wheel track is in the range 1.5 to 3.5 kg/m 2 .
  • the finished road surface provided by the invention may appear such that the road surface with a filled wheel track immediately after finishing appears with excess height in relation to the surrounding road surface. By this is achieved that the surface may get the same profile as the rest of the road when traffic has compacted the material filled into the wheel track.
  • a lower layer of stone material 3 consisting of particles with relatively large particle size, e.g. size 8/11 (meaning screen fraction size 8-11 mm) is laid.
  • This lower layer covers the deepest parts of the bottom of the wheel track 1 and almost to the edges, where the surface 1 of the wheel tracks continues into the road surface 2 level.
  • the lower layer 3 may e.g. consist of 12 kg/m 2 diabase.
  • the material is applied with a aggregate spreader or sledge.
  • a layer of binder e.g. bitumen, which is not shown on Fig. 2 , but its cross-wise distribution appears on Fig. 1 .
  • a greater amount of binder is sprayed at the deepest point of the wheel track 1, i.e. with more around the centre of the wheel track 1 than at the areas close to the edges of the wheel track.
  • the distributing is performed by programming existing and known spraying equipment which is computer-controlled.
  • the increased amount of binder laid on the lower layer 3 of stone material in the wheel track 1 may be graduated as shown on the curve on Fig. 1 .
  • the binder may e.g. be Biostyrelf TM bitumen where 100% on the vertical axis in Fig. 1 corresponds to 1.4 kg/m 2 .
  • the amount of binder at the deepest point of the track 1 is 2 kg/m 2 , i.e. about 42% more than the amount of binder along the edges of the track.
  • an upper layer of stone material 4 of particles with relatively small particle size e.g. size 4/8 (screen fraction 4 - 8 mm).
  • the upper layer 4 lies in an even layer across the entire width of the wheel track 1 right up to the edges. It is preferred that in the same operation, the layer 4 is also laid in a strip along each side of the track 1 in order thereby to achieve an even transition to the existing road surface 2.
  • the upper layer 4 may e.g. consist of 14 kg/m 2 diabase.
  • an excess height may be provided in relation to the level of the surrounding road surface 2 such that the filled wheel track may achieve the same profile as the road when the traffic has compacted the material.
  • bitumen types used in the binders may be:
  • the stone materials may be:
  • Typical combinations of particle sizes may be fractions in overlapping or discrete sizes, where bottom layer and top layer, respectively, consist of following fractions:
