A road marking and a method for road marking

Abstract

A road marking ( 10 ) has bristles ( 11 ) extending above a road surface level ( 12 ). The bristles ( 11 ) are attached below the road surface level ( 12 ), leaving a recess ( 13 ) between the road surface level ( 12 ) and the bristles ( 11 ). The recess ( 13 ) allows the bristles ( 11 ) to bend below the road surface level ( 12 ) during snowploughing. The forces exerted to the raised road marking ( 10 ) do not pull the bristles ( 11 ) or the whole road marking ( 10 ) assembly off the road surface. The bristles ( 11 ) may be installed into the road surface by cutting a suitable cavity ( 15 ) into the road surface. A bottom portion of the cavity ( 15 ) is filled with a fluid adhesive, leaving the surface of the adhesive below the road surface. The bristles ( 11 ) are inserted in the fluid adhesive. After the adhesive has been cured, the bristles ( 11 ) stand proud from the road surface.

1 . A road marking, comprising:
 bristles extending above a road surface level; and   a first adhesive for the bristles, arranged to a cavity formed below the road surface level;   characterized in that:   the cavity comprises a recess, arranged to the outer perimeter of the road marking, between the bristles and the road surface level, allowing the bristles to bend into the recess below the road surface level.   
     
     
         2 . A road marking according to  claim 1 , characterized in that a second adhesive is configured to adhere to the first adhesive and to the cavity formed in a road surface material. 
     
     
         3 . A road marking according to  claim 1 , characterized in that the first adhesive comprises the same material as the road surface. 
     
     
         4 . A road marking according to  claim 1 , characterized in that the first adhesive comprises bitumen. 
     
     
         5 . A road marking according to  claim 1 , characterized in that the cavity is a V-shaped cavity formed in the road surface material by two blade cuts. 
     
     
         6 . A road marking according to  claim 1 ,
 characterized in that the lower portion of the road marking comprises a lighting element and the bristles allow light from the lighting element to pass through above the road surface level.   
     
     
         7 . A road marking according to  claim 1 , characterized in that the road marking is recyclable in a recycled road surface pavement. 
     
     
         8 . A road marking according to  claim 1 , characterized in that the bristles comprise luminescent, photoluminescent, fluorescent, phosphorescent or light-reflecting material. 
     
     
         9 . A method for a road marking;
 said road marking comprising bristles above a road surface level; and
 a first adhesive for the bristles, arranged below the road surface level; 
 characterized in that the method comprises: 
 forming a cavity into a road surface; 
 providing the first adhesive into the cavity, wherein the first adhesive is fluid and a surface level of the first adhesive is below the road surface level, forming a recess arranged to the outer perimeter of the road marking, between the bristles and the road surface level; and 
 putting the bristles into the first adhesive. 
   
     
     
         10 . A method according to  claim 9 , characterized by providing a second adhesive into the cavity before the first adhesive and adhering the first adhesive onto the second adhesive. 
     
     
         11 . A method according to  claim 9 , characterized in that the first adhesive comprises the same material as the road surface. 
     
     
         12 . A method according to  claim 9 , characterized in that the first adhesive comprises bitumen. 
     
     
         13 . A method according to  claim 9 , characterized by forming the cavity as a V-shaped cavity by two cuttings of the road surface material by two blade cuts. 
     
     
         14 . A method according to  claim 9 , characterized by cutting the bottom portion of the cavity by two intersecting blade cuts. 
     
     
         15 . A method according to  claim 9 , characterized by recycling the road marking in a recycled road surface pavement.
