A CONTRIBUTION TO THE ESTABLISHMENT OF DESIGN LOADS FOR THE THICKNESS DESIGN OF FLEXIBLE ROAD PAVEMENTS

Theoretical and empirical research is constantly producing new ideas on flexible pavement design, but these are not being incorporated in the principles used in actual practice for assessing useful design loads. This report is designed to draw attention to research that has been done on the specification of service load data for roads in the Federal Republic of Germany. It also outlines the work that remains to be carried out in the future. It lists initially the requirements that are currently made for loading data for flexible pavement design and indicates possible ways of simplifying data presentation. The report deals with surveys already carried out on service loads: starting with the pattern of stress distribution between truck tires and carriageway surface, it discusses vertical axle loads assessed in permanent surveys as well as sample and indirect surveys. It also deals with the data required on loading periods and loading points. Explanatory measurement examples are cited for various characteristics of truck traffic. Finally, the report takes current loading data requirements and available data as a basis for indicating what still has to be done in flexible pavement design research to establish design criteria for the service loads of roads. /AUTHOR/
