İSFALT made the mastic asphalt application on 520-meter-long Karamağara Bridge in the Ağın district of Elazığ in 2015. The application on the Karamağara Bridge, one of the largest steel suspension bridges in Türkiye, was implemented using the asphalt produced in Istanbul and transported to the region.

This transportable application of mastic asphalt, which is produced at high temperature and then cooled in molds and transported to the region, was implemented for the first time in Türkiye. Mastic asphalt was produced in ISFALT factories in Istanbul and transported to the region in 1-ton molds, then it was converted in special machines and applied to the Karamağara Bridge.
