• Abstract:
  As part of the FHWA ASR Development and Deployment Program, two sites were built to study ASR in new concrete construction. Concrete blocks were produced with a range of aggregates and cementitious materials and placed on outdoor exposure sites at the University of Hawaii in Manoa on the island of Oahu and at a DOT storage facility in Lawrence, Massachusetts. The main purpose of these studies was to (i) provide information on the reactivity of local aggregates which could be used as a benchmark to calibrate standard laboratory tests, (ii) determine the efficacy of various preventive measures for controlling ASR expansion, and (iii) provide data to validate guidelines such as AASHTO PP65-11. This document presents the preliminary findings from the Oahu and Lawrence exposure sites.
