Shear behavior of hydraulic asphalt concrete at different temperatures and strain rates
Highlights Slant shear apparatus developed for testing asphalt concrete. Shear tests conducted at different temperatures and shear strain rates. Time-temperature superposition principle is confirmed. Shear modulus and strength values to be used for different loading conditions.
Abstract Asphalt concrete is a viscoelastoplastic material and its behavior depends on temperature and time. Asphalt concrete used as impervious core in embankment dams is subjected to different loading conditions at different temperatures. A shear apparatus is described and used to investigate the stress-strain-strength behavior of asphalt concrete by carrying out shear tests at different temperatures and shear strain rates. The domains of shear modulus and shear strength values of asphalt concrete are established by applying the time-temperature superposition principle. Shear modulus and shear strength values of asphalt concrete for different loading conditions are compared. The documented behavior can be used in the design of the asphalt core in embankment dams.
