Betongbeläggning i tungt trafikerade körfält på motorväg: exempel och erfarenheter från några olika länder

On Swedish motorways the majority of traffic tends to drive in the right hand side lane. The left hand side lane is used mainly for overtaking and by light traffic. Traffic loading conditions are therefore very different in the two lanes. For an optimal road design, each lane would be designed to match the traffic load associated with that lane. This means that a stronger construction should be designed for the right hand side lane. An optimal solution could be to use a combination pavement with a concrete construction in the right hand side lane and a bituminous construction in the left hand side lane. The purpose of this project is to develop a combination pavement with asphalt next to concrete as is being used abroad, but only been tested in a small scale in Sweden. By using a concrete pavement in the heavier trafficked right hand side lane and asphalt in the left hand side lane the two materials will be used in an optimal way. The method being used is a literary survey, practical experience, national and international experiences.
