    The aim of the HVS tests was to study the influence of the road cross section and edge effects on the structural strength and permanent deformations of low-volume roads. The test consisted of three test sections: one without slope, one with 1:3 slope and one with 1:1,5 slope. The test sections were loaded with Super single wheel and the loading changed from 30 kN to 50 kN. Also the level of the water were changed during the test. The biggest part of the permanent deformations happened in the base layer of crushed rock in the depth between 50 to 450 mms. A factor of geometry was introduced to be able to estimate the effect of width of the road the steepness of the sideslope to rutting speed. A clear growth in the deformations was detected once the elastic deforamtions corresponding to the certain stress state had crossed a particular threshold value. This means that the 'shakedown' value was crossed.
