Abstract:

In order to explore the influence of salts on the low-temperature rheological properties and adhesion properties of asphalt mortars, preparation method of asphalt mortars with salt particles replacing mineral powder by volume ratio 1:1 and the bending beam rheological test (BBR) were used to study the effects of different salt-doped asphalt mortars on the low-temperature rheological properties at 30 d and 120 d test age. The corresponding Burgers model was built to analyze the effect of salinity on low temperature viscoelasticity of asphalt. Through the contact angle test, the surface energy parameters of asphalt were obtained, and the adhesion characteristics of different asphalt mortar were evaluated. Scanning electron microscopy (SEM) and infrared spectroscopy (FTIR) were used to explore the microscopic mechanism of salt-doped asphalt mortars. The results showed that compared with control asphalt, the rheological property of salt-doped asphalt mortars at low temperature decreases with the increase of age. At the age of 120d, the contact angles of asphalt increase obviously, the surface energy of salt-doped asphalt mortars decreases and its adhesion property degrades. The dissolution and crystallization process of salt particle and its salt aging effect are the main inducing factors of performance deterioration of salt-doped asphalt mortars.

Key words: road engineering, salt, asphalt mortar, low temperature rheological characteristic, contact angle, adhesion characteristic, salt aging effect
