On behalf of the Swedish Transport Administration VTI has performed transverse profile measurements and wear measurements on test sections with polymer modified asphalt pavements on road 47 at Falköping. The purpose of the surveys is to evaluate the different types of wearing course regarding rutting and wear of studded tires and durability / stripping (loss of surface aggregate). Within the rehabilitation project for the road 2011 test sections with various types of surface course where constructed where six test section of 200 meter long was selected for further evaluation. The monitoring of these test sections include, in addition to test sections with polymer modified bitumen type Nypol and Inormix also connecting reference sections with conventional asphalt paving with standard bitumen (std) B70/100. The amount of traffic, AADT, on the test sections is about 4 500–5 000 vehicles. Profile measurements have been conducted annually from 2011 until the spring of 2014. On each test section was wearing of studded tires measured in 5 transverse profiles and profile measurement for rutting with equipment Primal in 10 transverse profiles and measurement of durability / stripping of 1 m2 over the left wheel track and the edge of the track.
