Installation Guidelines Lefix Banquette slabs

General Guidelines

  1. The proper tools should be used for the installation of the banquette slabs, ( e.g. BG installation tools) for banquette slabs from BG Graspointner) and the corresponding hoisting gear (e.g. Mobile crane, excavator etc...).

  2. The roadway connection should have a constant height of min. 5 mm higher than the surface of the banquette slab  

  3. Existing insertion apertures for the sign posts have to be kept free, respectively made deeper. 

  4. Not only does the banquette slab serve as a road widener, but also as a safeguard for the roadway verge in the area of the banquette. (Constant driving on the shoulder should be avoided)

New building constructions:

  1.  A bedding capable of withholding constant heavy load capacities must be made according to the current road building regulations and the weight classes which are to be expected.

  2. The banquette slabs are laid on a bed of gravel (5/8) having been made compact using a pile-driver. The slabs can be laid in the same way in an earth-moist concrete substructure. Pay attention to the fact that the banquette slabs are inserted with a total surface contact.
  3. A rear buttress (e.g. concrete) should be inserted to avoid any potential sideways shifting of the slabs.

  4. When constructing the road surface (bitumen wear and tear layer, concrete surface) it is most important that the banquette slab be connected in close proximity.

Restoration:

  1. The soft shoulder should be cut or mowed, to create a clean feeder line enabling damaged road surface to be professionally removed.

  2. Removal of previous banquette material.

  6. The gaps between (the cut) verge of the roadway and the banquette slabs, must be filled with adequate socketing mass (mastic asphalt or asphalt emulsion).
