Experimental Study on the Viscoelastic Properties of Asphalt Concrete under Chloride Corrosion

Abstract:

In the paper, uniaxial compression creep tests were carried out at 25°C after the asphalt concrete corroded by different chloride solution concentrations, suffering different times of diurnal temperature variation cycle. Creep stiffness module and the ratio of residual strain were employed to evaluate the viscoelastic properties of asphalt concrete. According to the winter in Wuhan district, the viscoelastic properties of asphalt concrete under the action of chloride corrosion together with day-night cycle were preliminarily studied, and the corresponding viscoelastic parameters were determined with the help of Burgers model. The results show that chloride corrosion and day-night cycle can separately affect the viscoelastic properties of asphalt concrete, and the influence becomes severer while they act together.
