Expansion joints mageba flexible plug expansion joint – the new generation maximum driving comfort, wear-resistant, watertight

Expansion joints Product Characteristics Principle The new POLYFLEX®ADVANCED PU Flexible Plug Expansion Joint System achieves a completely new standard in terms of quality and working life. The POLYFLEX®Advanced joint uses a durable fully elastic material with an enormous tear resistance and low reaction forces. Perforated steel angles within the PUmaterial help to accommodate horizontal braking and reaction forces and allow for a clean bond between surfaces free of leakages from ingressing water. Compared to other expansion joint designs, flexible plug expansion joints offer several advantages...

Client Benefits Advantages & Properties • Exceptional long working life, longer than adjacent surfaces • Highest possible driver comfort • No noise from crossing traffic due to surface that is flush with adjacent road • Watertight • 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....

Design Details & Movement Capacity Design Principles The 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...

Expansion joints Testing and Verification 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 flexible plug joint systems with the following results: Estimation of working life: conventional asphaltic plug expansion joints (picture ①) BT 16 HS LKS (common asphaltic surfacing) POLYFLEX®ADVANCED PU (picture ②) In practice, this means that the expected working life for POLYFLEX®ADVANCED PU flexible plug expansion joints will be more than 2 times higher than the working life...

Expansion joints 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 POLYFLEX® Advanded 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 at 60 °C (140 °F). Reaction...

Expansion joints Materials & Installation Material Description 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 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. If the joint is installed upon a concrete support, the minimal nominal compressive strength must be 25 N/mm!. To ensure watertightness of the whole system, the waterproofing membrane shall be applied up to the bridge gap. During installation of the POLYFLEX®ADVANCED PU joint, the waterproofing is cut and integrated into the PU material or the polymer concrete substructure. Consulting mageba offers...
