Расчет напряженного состояния Богучанской плотины с помощью новой модели асфальтобетона

Application of new model of asphaltic concrete for analysis of behavior of rockfill dam with asphaltic concrete core

The new two-phases visco-elasto-plastic model of asphaltic concrete (AC) was developed. The model consists of liquid (bitumen) and solid phases (aggregates). Behavior of bitumen was simulated by visco-plastic Maxwell-Norton model and behavior of aggregates - by elasto-plasic Cam-Clay model. New model was used in analysis of stress-strain state of Boguchansk rockfill dam with AC core, which is under construction note»
