ABSTRACT
The so-called RSOs are the first set of standardized guidelines in Germany to describe a systematic approach to structural assessment of pavements at project level. The target group includes both public road construction authorities and private operators. For asphalt pavements, the procedure is fully described; for concrete pavements, the rules and regulations are currently being drawn up. The method is based on the principles of mechanistically-empirical pavement design and requires testing on drill core samples within predefined structurally homogeneous sections. For the formation of the sections, non-destructive testing methods are used in particular, which will also play a greater role in the assessment in the future. The transfer of the principles described for application at the project level to the network level is a goal that is pursued in ongoing research projects. The paper describes the method.
