Effect of hydrated lime on linear viscoelastic properties of asphalt mixtures with glass aggregates subjected to freeze-thaw cycles

Abstract

This paper focuses on the effect of hydrated lime on the linear viscoelastic (LVE) properties of asphalt mixtures with glass aggregates subjected to conditioning: 1) 14 days in hot water and 2) repeated freeze-thaw cycles. Complex modulus test was used to evaluate LVE properties. Three glass aggregates (0%, 20%, 60%) and two hydrated lime (0%, 2%) content were studied. Results show LVE properties of samples with glass aggregates (0% hydrated lime) are greatly affected by conditioning. Adding hydrated lime to samples with glass aggregates significantly reduce the variation of LVE properties due to conditioning.
