BORNIT® Joint Flex® is used to provide flexible and permanent seams upon application of asphalt mix lanes (“hot on cold” as well as “hot on hot”) as well as for seams between asphalt surfaces and construction materials with irregular surfaces (milling edges). Main area of application is the mechanical pre-treatment of the centre seam flanks when applying hot mixes.
For cut asphalt edges, using BORNIT® Joint Tape is recommended!
 
BORNIT® Joint Flex® is a polymer-modified, solvent-free, stable bitumen compound, resistant to frost down to -5 °C. Using BORNIT® Joint Flex®, according to ZTV Asphalt StB 07, highly flexible and permanent seam connections are provided for seams in asphalt road construction. The product is manufactured ready-for-use and is usually applied mechanically with the processing equipment BORNIT® Flexomat 3.1 and Joint Module or, for base and binding layers, with the Edge Module, resp. Layer thicknesses up to 4 mm can also be applied at vertical seam flanks without any problem.
 
solvent-free, thus no impairment of the binding agent in the seam area as with solvent-containing seam adhesives
application of the material quantity specified according to ZTV Asphalt-StB 07 in one go (stable up to 4 mm of layer thickness)
highly flexible, elastic and good adhesive effect also on slightly moist substrates
cost-effective and time-saving machine application
with BORNIT® Flexomat 3.1 + Edge Module, application of the material for base and binding layers over the entire surface is possible in one go
