This examination paper has been written by direction of Vägverket Region Syd. Swedish road network is being adapted to the European standard, but there are still many restrictions left on minor roads. We don’t have sufficiente knowledge of what problems these restrictions involves for heavy transports and Vägverket is anxious to map and find out what advantage it should be to do reinforcements. I have investigated a rural district in the South of Östergötland and the restrictions that exists here on several roads are low carrying capacity, especially on bridges, and high risk for frost damages. The purpose of this investigation is to map out the heavy transports and the problems that the restrictions on the roads leads to. I have used both theoretical and empirical studies. The theoretical studies can be divided in: · Common technical description for road contractions · Laws and regulations for heavy vehicles · Information and reports from Vägverket · Earlier investigations The empirical studies consist of interviews with different conveyors in the area. The interviews have been made to get a picture of how the conveyors takes the restrictions of the road network and how it affects their activity both practically and economically. I have interviewed both big companies as Södra Skog, Arla and Odal and smaller road carries with a few lorries. My conclusions are: · There are four roads in the investigated area that should be given priority to reinforcements and to secure from frost damages. · Vägverket should investigate the possibilities to guarantee an easy and flexible contact between the road carriers and the ones that are responsible for the maintenance of the roads. · It seems better to keep the smaller gravel roads that still exists and maintain them better with planing, gravel and perhaps draining instead of putting on a thin asphalt surface, which is very sensitive to heavy traffic and frost damages.
