Description
| - Alkali-silica reaction produces deterioration of concrete, visible on the macro-and micro-scale. Macro-indicators of alkali-silica reaction are important in the field inspection of concrete. Micro-indicators help to verify the presence of alkali-silica reaction and make it easier to distinguish ASR from other degradation mechanisms. Three parameters were determined to evaluate the deterioration of concrete pavements: the specific length of cracks measured on the pavement surface; the specific length of cracks in the drill cores; and the volume of alkali-silica gels and microcracks in thin sections. According to these indicators, it was possible to distinguish two types of pavement degradation: degradation mainly associated by ASR and degradation connected with another mechanism. The macro-and micro-indicators linked the deterioration to alkali-silica reaction in six sites on the Czech highways. One site was attributed to another degradation mechanism. The rock types (and/or quartz recrystallisation of aggregates) affecting ASR were determined.
