Alkali-Silica-Reaction (ASR) of concrete pavements on roads, bus traffic areas and par- king spaces in the municipal sector

This research project in the field of municipal traffic areas was aimed at basic findings for a practice-oriented classification of the moisture class and the respective assessment of concrete by means of a performance-test. For this purpose concrete pavements without showing signs of a damaging ASR after approx. 10 years of use were tested. From this pavements drill cores were taken and assessed with a procedure especially developed for the moisture classes WA.
