The results of measuring the concrete expansive strains due to Alkali-Silica Reaction (ASR) are presented for four high strength concrete bridge structures. It is concluded that some of the structures are expanding at significant rates at an age of 10 years even though they are already severely cracked due to ASR. Other structures have stabilised at an age of 10 years and subsequent expansion is expected to be minimal. The collection of this field data indicated that the concrete structure by ASR exhibited a maximum strain in the vicinity of 5000 microstrain after 12 years. This is important information to input into an accelerated testing programme for ASR and forms the basis of another paper in this series.
