Alkali Silica Reactivity Surveying and Tracking Guidelines
Primary Topic: Materials-Concrete
Description: This document is intended to serve as guidelines for State highway agencies (SHAs) to survey and track transportation infrastructure affected by alkali-silica reactivity (ASR). The focus of the guidelines is to assist engineers, inspectors, and users in tracking and surveying ASR induced expansion and cracking in bridges, pavements, and tunnels. The guidelines are simple and are intended to collect, quantify, and rank typical signs of ASR distress, based primarily on visual inspection.
