The main objective of the R&D project is to propose a set of more reliable ASR performance test methods for national and international application (via RILEM TC "258-AAA" on ASR (2014-2019), in which Norway has the leadership). The basis for the research work is results from the COIN program (2007-2014).

A central part of the R&D project is to calibrate results obtained in accelerated laboratory testing against long-term field behaviour, primarily by annually following up the about 95 monitored concrete cubes exposed at the two established field exposure sites in Trondheim and Lisbon.

As part of the co-operation with RILEM TC 258-AAA, the project has produced 81 supplementary monitored cubes that are being exposed on 10 field exposure sites in Europe and North America (incl. Trondheim and Lisbon). In November, the two years results for the latter cubes were presented for the RILEM TC and the project partners.
