For many years, there has been a growing need in Norway for improved expertise in road technology. Many older roads need reconstruction or strengthening, and premature failures are occurring too often on new roads—sometimes because of low-quality work and the improper use of materials. In addition, changes in traffic loading, climate, and materials, as well as in production methods and equipment, have made it necessary to revise current guidelines.
The Norwegian Public Roads Administration (NPRA) launched the Durable Roads program in 2011. The goal of the four-year research program, which wrapped up in 2014, was to achieve increased pavement service life and reduced annual cost for the Norwegian road network. The program focused on three main topic areas: road surfacing, structural design and strengthening, and knowledge dissemination and implementation.
