After two intensive years, the construction company NCC has finished asphalting the 23 km stretch of the E18 between Arendal and Tvedestrand in southern Norway.
The Danish State is currently building the new Storstrøm Bridge between Zealand and Falster. The bridge, which is part of the planned Fehmarn Belt link between Denmark and Germany, has a budget of approx. EUR 560 million and will open for traffic in 2022.
Skanska has been renovating large parts of the runway at Göteborg Landvetter Airport. Bitumen Matters was there to experience an intensive night of work as renovations progressed.
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.
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.
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.
In summer 2017, Nynas delivered a carefully chosen PMB grade, Nypol 25, for asphalt layers of a test track.
“Traditional but innovative” might sound like something of a contradiction, but it is actually the formula for a successful asset management strategy for highway maintenance.
Combining a polymer-modified emulsion with two aggregate fractions gives you an especially durable surface. This was one of the main reasons why the contractor Skanska and the Swedish Transport Administration chose to use this technique on a road project in northern Sweden.
Most local authorities in the UK think of cold mix asphalt as a new and relatively untested road construction material. But it has been used successfully in the UK for more than 10 years, including a section of trunk road in Scotland built with a cold mix asphalt base course in 2008.
From this spring until October 2019, NCC will be laying no less than 300 000 tonnes of asphalt on a new section of motorway along the south-eastern coast of Norway.
A successful collaboration between Nynas and volumetric concrete mixer manufacturer Armcon has resulted in a mobile patching machine that can produce cold mix asphalt for repairs and maintenance.
The Hålogaland bridge is located 300 km north of the Arctic Circle, and crosses a fjord by the city of Narvik in northern Norway.
When a new bridge is built it involves major investments, strict quality requirements and an ability to efficiently coordinate different technical teams.
