Areas of application
BORNIT® Joint Tape 7 CSA is particularly suited for use at rectangular joints and connections in new construction and refurbishment of asphalt roads for:
• better bonding for lateral connections (roadway extension, etc.)
• utility trench construction (re-closure of the trenches with hot asphalt)
• more durable winter and pothole repairs and for achievement of better flexibility between
• old (cold) and new (hot) asphalt
• secure connection to roadway installations, like manhole covers, valve and hydrant
• covers, road drains

Type and properties
BORNIT® Joint Tape 7 CSA is a polymer-modified, bituminous and cold self-adhesive joint tape for asphalt road construction.
BORNIT® Joint Tape 7 CSA is a patented special profile with a strong adhesive layer on the assembly side. The special shape in combination with the adhesive coating guarantees easy, fast and secure application, in particular for joint flanks at right angles (e.g. cut). Due to the adhesive layer, the tape is fixedly attached to the joint flank. With its special shape, insertion with a defined assembly protrusion (for secure formation of rivet heads) is simultaneously guaranteed. This substantially facilitates the formation of a uniform joint pattern and thus professional waterproofing of asphalt seams and connections. Since flame heating is not required, the joint tape can be easily and quickly laid by one person.

BORNIT® Joint Tape 7 CSA has been tested according to ZTV Fug-StB 15.

Processing
Free the vertical and straight joint edges and roadway installations from adhering dirt or rust, if applicable. Unroll BORNIT® Joint Tape 7 CSA, cut it to length and press it onto the contact surface with its adhesive side using a flat tool or by hand. Due to the special shape (“designed assembly claw”), the joint tape is provided with its defined protrusion at the joint flank. At the corner points of an opening, the tape is blunted. The secure connection of the joint tape between old and new asphalt is supported by the asphalt mix to be applied hot. The narrower joint tape shape in the lower area minimises the risk of voids in the asphalt below the joint tape. Following insertion of the hot mix, the protrusion of the joint tape is rolled to obtain a smooth surface.

If the asphalt delivered should not have the necessary application temperature, this may also affect the seam connection! In order to achieve an even better flank adhesion, e.g. in case of contaminated and dusty substrates, priming with BORNIT® Hot Compound Primer or BORNIT® Hot Compound Primer Fix is recommended.
