MODELS FOR PREDICTING RUTTING ON ASPHALT ROADS. ANALYSIS OF ASTO TEST ROAD DATA 1990-1997

The aim of this study was to develop models for predicting rutting. The data consists of rut depth and wearing area measurements which were made on 14 roads between 1990 and 1997. Wearing has decreased by 30 % on average since 1991-1994. Weather conditions have a great influence on wearing.
