Abstract [sv]

Today the Swedish Road Administration (SRA) regularly follows up the condition of the state roads by means of road surface measurements. It is mainly rut depth (mm) and roughness expressed in the measure International Roughness Index (IRI, mm/m) that is the bases for assessment of the road surface condition. Based on these measurements it can generally be said that the condition of the roads neither have considerably improved nor become considerably worse over the years. The trend however looks a bit different in the different SRA Regions. At the same time it is also yearly investigated how content or discontent the road users are with the maintenance of the state roads. The road users are asked about their opinion on the operation and maintenance of the roads in general as well as more specifically about their opinion concerning rutting and unevenness, i.e. the factors that are followed up by measurements. The general tendency, except for the last year, is the percentage of satisfied road users is decreasing. The percentage of satisfied road users is also low. This applies not least that the professional drivers. The agreement between the objective measurements of the condition of roads (or rather the condition measures that are used) that are done and the opinions given by the road users is not very good. There is reason to go deeper into this question and examine what requirements and expectations the road users have on the roads/road surface condition and also what measures are needed to describe the condition in a satisfactory way.
