Constantly increasing traffic densities and loa-dings lead to shorter intervals between rehabilitation and maintenance for standard traffic pavement construction me-thods. Therefore, the use of a more durable construction me-thod offers enormous potential in this context and in terms of economic aspects. While continuously reinforced concrete pavements have been used abroad in a long time, their application is still limited to a few road sections in Germany. Missing technical specifications as well as a systematic consideration of the optimisation potential, especially with regard to crack control, restrict the practical application. In the course of this paper findings on cracking mechanisms and influencing factors on the cracking initiation in continuously reinforced concrete pavements will be given. Experiments with different boundary conditions are evaluated with regard to crack formation and crack propagation as a result of different actions, e.g. from concrete hydration, varying environmental conditions and traffic loads. Furthermore, numerical investigations are carried out regarding the influence of concrete hydration in re-lation with the begin of concrete hardening at different dayti-mes and varying fresh concrete temperatures.
