Some concrete pavements commonly used at airports are susceptible to the destructive effects of alkali-silica reaction (ASR). The presence of ASR on concrete pavements can have a devastating effect on pavement performance, not only in terms of reduced functionality, but also in terms of shortened service lives.
The focus of ACRP Synthesis 96: Practices to Mitigate Alkali-Silica Reaction (ASR) Affected Pavements at Airports is on current practices for mitigating ASR in affected pavements at airports. Given the substantial initial investment required for pavement, airports are interested in using mitigations to slow the effects of ASR and prolong the life of airfield concrete pavements.
This synthesis identifies the current state of the practice regarding the mitigation measures used on existing ASR-affected airport pavements that service aircraft and summarizes the experiences and practices of airports in dealing with the distress (including conventional treatments, but also any new or emerging technologies).
