Laboratory Reproduction of Pavements with Good Long-Term Performance in the Field: Methods, Goals, and Outlook

Normally, when designing a new mix, testing is done using new components. Testing can include standardized aging of mix or binder in some cases. An example is the short and long term aging developed during the SHRP-project. Since there are dam-ages linked preferably to early life as well as later life, the investigation of such an artificially aged pavement is of considerable interest. In the framework of a research project focusing on durability of components as part of the mix, highway sections which were in use under heavy traffic for many years were investigated. To study the link between components and the compacted material, selected layers of these successful sections were reproduced in the lab. To this end, an appropriate aging method depending on the state of the pavement had to be developed. In addition, the original materials were no longer available in the strict sense of the word. Consequently, new material had to be used. The goal was to find clues to why the road sections were so successful and to correlate their observed damages with the findings about their lab counterparts
