Mastic asphalt is an ideal construction material for absorbing dynamic stresses that occur on bridges. It meets the required elasticity values and, on the other hand, simultaneously ensures the necessary stableness of the bridge. The results are a permanent waterproofing and a long life. Mastic asphalt can be used on steel bridges, concrete bridges and wooden bridges. In a life cycle cost analysis, mastic asphalt always swings out at the top of bridges; the use of mastic asphalt always pays off.
