MAURER XW1 - Expansion Joint The wave shaped MAURER Single Seal Expansion Joint Gap width up to 100 mm – like XL 1-Expansion Joints Reduced noise emission – like XL 1-Expansion Joints Maintenance free – like standard single seal expansion joints Type approved according German specification TL/TP FÜ This further development of the single seal expansion joints combines the relatively simple design principle of the known strip seal expansion joint (2 edge beams + 1 strip seal) with level difference when passing this expansion joints, in relation to the undisturbed asphalted carriageway. MAURER XW1 MAURER XW1 wave shaped Expansion Joint the advantages of the XL-1 expansion joint (reduced noise emission+ maximum gap width 100 mm. Instead of bolted and wave shaped edge plates, the edge beams which are firmly anchored into the adjacent concrete are being designed in a wave shape. This way the role of the “kerb unit” which is taken by the straight edge beams of the expansion joints is being dissolved, and an optimum of noise protection is attained. Comparing the noise emission of this design with earlier measurements of the noise level leads to the result that this design emits the lowest noise MAURER XL1 MAURER D80 Finger Joint MAURER D 400 GO MAURER D 400 0 Noise level difference between expansion joint and carriageway [BASt-Study 96 221/B2-V3 and Müller BBM-Report M90 658/1]

MAURER XW1 – Expansion Joint The wave shaped MAURER Single Seal Expansion Joint In addition to the known advantages of the XL1 design like the redundancy of the maintenance access in case of movements of up to 95 mm (movement range 5 mm to 95 mm) and reduced noise emission for the neighbourhood, the system “XW1” displays the following features: No additional bolted wave plates are required in order to reduce the noise emission – thus the self cleaning effect of the gap is no longer reduced. No more bolted connections to check. The patented and flexible sealing element gurarantees by way of a...
