Bridge sealing Schettelbach bridge

Road sealing despite cold ensures successful opening

Until now, the federal highway 29 (B 29) ran through the village of Mögglingen. In 2015, construction began on the new bypass, which will massively reduce traffic in the town. The local bypass crosses 14 new bridges, including the Schettelbach Bridge with bridge areas of 912 and 928 m² as well as Structure 9 with approx. 200 m². The inauguration of the bypass was scheduled for April 2019. However, since temperatures around -5 °C prevailed at night and +8 °C during the day around the sealing of the two bridges, the use of a material that cures in only 20 minutes under such weather conditions was required. The choice fell on the PMMA system structure with Wecryl 123 primer resin as sealer, Vedag VEDAPONT BE polymer bitumen sheeting and two layers of mastic asphalt. In this way, the specifications of ZTV-ING 7.1 could be realized.
