TRIBOLOGICAL TESTING OF TRADITIONAL ROAD-GRADING STEELS LEADING TO THE EVALUATION OF NEW ROAD PREPARATION CONCEPTS

In 1983 conventional road-grader steels of major nordic manufacturers were evaluated in a number of laboratory tests as well as by extensive field testing. The overall conclusion was that there were no significant tribological differences between the tested steel grades. This result inspired a broader tribological approach to the improvement of the economics and performance of road-grading and ice-cutting equipment. This paper presents the technical requirements for the grader blade. It also defines a number of important tribological rules to be obeyed in the design and choice of material for novel grader blades. Finally, a number of new improved tools, meeting these technical requirements and tribological rules are presented. The novel systems have been successfully introduced in the scandinavian countries. The technological and economic benefits are presented. (TRRL)
