Product CharacteristicsPrinciple The TENSA®POLYFLEX®Advanced PU Flexible Plug Expansion Joint System achieves a completely new standard in terms of quality and service life. Compared to other expansion joint designs, flexible plug expansion joints offer several advantages including: unsurpassed driver comfort, no added noise emission, watertight, installable in sections (e.g. lane-by-lane), etc. Traditional bituminous based expansion joint materials have several disadvantages. Softer materials with lower reaction forces are not sufficiently stable and deform plastically at high temperatures and...

Client Benefits Advantages & Properties • Exceptional long service life, longer than adjacent surfaces • Highest possible driver comfort • No noise from crossing traffic due to surface that is flush with adjacent road • Maintenance-free; cleaning not required • Suitable for new structures and refur-bishments • Quickly installed lane-by-lane with minimal impact on traffic, drivable after a few hours (overnight installation) • Installation within a wide temperature range (5 °C to 35 °C/41 °F to 95 °F) • Wear-resistant; no mechanical wear parts • No rutting, high resistance to abrasion (e.g. braking...

Design Details & Movement CapacityDesign Principles The TENSA®POLYFLEX®Advanced PU filling material shows excellent adhesion to the supporting structure as well as to the adjacent surfacing, and is therefore capable of safely transferring horizontal loads to the structure. Additionally, perforated steel angles, which are fully embedded within the joint material, are bolted to the structure and can transfer even the highest loads (e.g. from heavy vehicles braking on the joint at downward slopes). These steel angles also support the adjacent surfacing so as to prevent the asphalt from being depressed...

Testing and Verification Estimation of working life: Wheel tracking comparison test A wheel tracking test according to EN 12697-22 was performed by the Testing Institute MAPAG in August of 2009. Testing was done on two different plug joint systems with the following results: In practice, this means that the expected service life for TENSA®POLYFLEX® Advanced PU flexible plug expansion joints will be more than 2 times higher than the service life of the adjacent road surfacing. At the testing facility of Technical University of Munich, Germany (Prufamt fur Verkehrswegebau, TU Munchen) tests of...

Expansion joints Testing and Verification Movement Capacity Test & Material Characteristics test At the Federal Institute for Materials Research and Testing (BAM) in Berlin, Germany, movement capacity tests according to ETAG 032-3, Annex 3-N have been carried out on a test sample of a PA 50 TENSA®POLYFLEX®Advanced PU expansion joint. During test method a) “Movement capacity under slow occurring movements“, the temperature of the specimen was controlled according to the applied movements. Therefore, the maximum tension of 33 mm was applied at -40 °C (-40 °F) and the maximum compression of 17 mm...

Expansion joints Materials & Installation Material Description TENSA®POLYFLEX®Advanced PU is an elastic, solvent-free 2-component grout system developed for the application of flexible plug expansion joint systems. The polymer concrete recommended for the support is a cold processed grout system adapted to the TENSA®POLYFLEX®Advanced PU joint in terms of workability and endurance. Technical data of PU material*) *) indications only.

Expansion joints Quality & Support Installation For new structures, the bituminous surfacing shall be made in advance. For concrete surfacing and at edge beams, adequate recesses shall be provided. mageba offers full technical support to help determine the proper joint width and details with consideration of all technical and economic aspects in order to calculate the optimum and most cost-effective solution. If the joint is installed upon a concrete support, the minimal nominal compressive strength must be 25 N/mm². To ensure watertightness of the whole system, the waterproofing membrane shall...
