Study on frost resistance of roller compacted concrete pavement

摘要

This paper presents the findings of the study on frost Resistance of roller compacted concrete pavement. Effective measures to improve frost Resistance of roller compacted concrete pavement by air entrapment are put forward based on test and study and successful solution of air entrapment and air content measurement technology. The mechanism of improvement of flexural strength and frost Resistance by air entrapment is expounded in terms of microstructure of the pavement.
