The handbook provides guidance for the field identification of alkali-silica reactivity (ASR) in portland cement concrete structures, such as highway pavements and bridges. ASR development is assessed on two bases: the occurrence and disposition of cracking and displacement of concrete, and the presence of reaction products from ASR. The handbook is divided into four sections. Section 1 describes the nature of ASR and its causes and effects. Section 2 shows the manifestations of ASR-related volume changes in highway pavements. Section 3 covers ASR in bridge structures. Section 4 describes a rapid field test to identify the presence of ASR reaction products in concrete. Color photographs show the results of ASR damage, as well as the results of the rapid field indicator test.
