detailed information


Product description
    
BORNIT®-Crack Tape consists in polymer modified bitumen, mixed with suitable filling substances. The special mixture of BORNIT®-Crack Tape awards an excellent sealing of cracks in the area of asphalt surfaces. It is permanent flexible and bridges cracks over a long time. It has a high low-temperature flexibility, an excellent adhesion to the asphalt surface and is self adhesive.

Area of Application 
   
BORNIT®-Crack Tape is used for the sealing of open cracks and rips up to 5 mm of breadth in the asphalt road construction. The tape covers the crack or rip area and prevents effectively the penetrating of surface water. The cold processing and therefore easy handling of BORNIT®-Crack Tape is in addition suitable for the build over with asphalt- mixing-materials. Preferably BORNIT®-Crack Tape is using for subordinate streets in the municipal road construction as well as cycle tracks and pathways because fast and simple renovation methods are there in demand.

Technical data

Type bitumen, crack-sealing tape
Base bitumen, polymers, additives
Colour black
Softening point after ring and ball > 80°C

Application 
   
The crack-/rip-area must be dry and free of dirt and unbonded material. Use of an emulsified asphalt tack coat is recommended to achieve an excellent adhesion.
After drying the bonding primer, BORNIT®-Crack Tape must be lay out and pressed on the crack area by roller, car tire or pounder. To avoid the tape sticking at the work equipment, it’s recommended to give some finely ground sand at the surface or remove the separating paper after pressing.
Note: The adhesive strength of the tape can be increased by easily warming the asphalt through a propane flame at underground temperatures below 10° C.

Important note
    
The causes for cracks in the asphalt are normally stresses and forces caused by most different influencing factors (e.g. insufficient bearing capacity of the foundation, defects during asphalting, etc.). Following an object-dependent service life of the repaired areas, cracks may therefore occur again and thus make a repeated treatment with BORNIT® Crack Flex necessary. A permanent repair of these damaged areas is only possible by eliminating the causes. A more durable repair of cracks is possible by proper milling out and subsequent filling with suitable hot sealing compounds (e.g. BORNIT Hot Sealing TL).
