Abstract
The data obtained by long time measurements of concrete pavements of test road sections with different structural designs on the A81 highway near Berolzheim and on the A6 at Ansback, with and without the conventional frost protection layer, shows that an increase in rutting, step formation, middle joint opening and loosening-up of the compound structure of concrete and the hydraulically bound carrier layer occur only after several years. The doweling of the heavily traffiched concrete lanes could not be avoided owing to step formation. The doweled concrete superstructure is adequately dimensioned with a concrete top thickness of over 22 cm for an axial load of 10 t. Continuation of long-time measurements is recommended.
