Anti-skid surface

Abstract

A device to slow down and/or stop means of transport on pavement, in particular a road pavement. The device includes a series of lamellar elements substantially parallel to each other, and provided with upper edges protruding from the upper part of the pavement, or substantially flush with the pavement.

1 . A device to slow down and/or stop means of transport on a pavement, in particular a road pavement, said device comprising a series of lamellar elements substantially parallel to each other, and provided with upper edges protruding from the upper part of, or substantially flush with, said pavement, wherein said upper edges define an anti-skid profile. 
     
     
         2 . The device as in  claim 1 , comprising cross pieces disposed inclined by an angle with respect to said lamellar elements to form a grid-type structure. 
     
     
         3 . The device as in  claim 2 , wherein said cross pieces have upper edges that define an anti-skid profile, said anti-skid profiles of said upper edges together defining an anti-skid surface. 
     
     
         4 . The device as in  claim 2 , wherein said cross pieces have notches mating in slot-in manner with respective notches present on said lamellar elements. 
     
     
         5 . The device as in  claim 1 , wherein said anti-skid profiles of the lamellar elements are made from a series of trapezoidal teeth disposed one after the other. 
     
     
         6 . The device as in  claim 3 , wherein said anti-skid profiles of the cross pieces are made from a series of square teeth disposed one after the other. 
     
     
         7 . An anti-skid pavement comprising at least one device to slow down and/or stop a means of transport as in  claim 1 , inserted in a seating made in the road pavement and partly covered by a covering layer. 
     
     
         8 . The anti-skid pavement as in  claim 7 , wherein the lamellar elements of the device are inclined with respect to the road surface by an angle comprised between 10° and 20°. 
     
     
         9 . The anti-skid pavement as in  claim 7 , wherein the anti-skid profiles of said device protrude with respect to a covering layer and are flush with the road pavement. 
     
     
         10 . A method to lay a device to slow down and/or stop means of transport as in  claim 1 , said laying method comprising:
 making a seating in a road pavement;   inserting said device in said seating;   covering said device with a covering layer, wherein said laying method provides to:   spread a sheet of plastic material over said device and said covering layer;   compress and level the sheet of plastic material in order to compact said covering layer and to insert at least said anti-skid profile inside said sheet of plastic material;   remove said sheet of plastic material so that said anti-skid profile is flush with said road pavement and protrudes by a height from said covering layer.
