Slitage på skogsbilvägar vid virkestransporter
This report discusses questions concerning wear on forest roads. The purpose of the work is to investigate if the wear on the roads will decrease when the speed limit gets lower for the trucks that transport the wood. A normal forest road, class B, was used in the study. In total 5000 m3f timber was transported on the road. Data about the road was measured with a profilograph car before and after the timber transport. Information about mark deep, IRI and texture was collected. The road was split in two parts, one with lower speed restriction than the other.
In conclusion there was no large wear difference between the two parts of the road. IRI was a little bit larger on the road where the speed limit was higher. The rut depth was almost the same before and after the test. One further result is that the mega texture was better after completing the transport than before.
