Punt Val Mulinaun, Switzerland

High-quality waterproofing of a bridge is generally carried out using mastic asphalt. This is all the more true if there are increased stresses due to climatic conditions or traffic loads. One example is the Punt-Val-Mulinaun arch bridge on the Oberalpstrasse H19 in Graubünden, Switzerland.

This construction was completed in 2017 and is situated more than 1 000 m above sea level. The company Aeschlimann AG uses project-specific construction systems for the waterproofing; in this case, the bridge pavement consists of 3 layers of mastic asphalt MA 11.

The application work was rail-guided in order to create an even and homogeneous surface. Part of the concept for a durable bridge pavement is the use of Nynas Endura N5, a specially developed Premium PMB, that delivers an optimal balance between workability and resistance to permanent deformations in the asphalt.

Sätaröd-Vä, Sweden

European route 22 (E22) is no less than 5,320 km long, from Holyhead in the UK via the Netherlands, Germany, Sweden and Latvia to Ishim in Russia. The part of the E22 that runs through Sweden plays a major role for the country’s southern region, not least because of the link to the Copenhagen area. The problem is that the road is very busy and accident-prone, and is also close to residential areas that are affected by noise.

The Rotebro Link, Sweden

County road 267 in northern Stockholm is an important, busy link between the E4 and the E18. To improve the traffic flow on this section, the contractor Svevia has been hired by the Swedish Transport Administration to widen a 6 km section from one to two lanes in each direction.
