Asphalt - an overview ScienceDirect Topics

Asphalt exhibits an absolute elasticity at an extremely low temperature but becomes a fully viscous fluid at a relatively high temperature. Within the range of common service temperature, asphalt is a typical viscoelastic material whose rheological properties are dependent on two factors: temperature and time.

First, the binder designated as 90A was heated to 155°C (or SBS MA was heated to 170°C); then the design contents of the GO (1.0 wt% or 3.0 wt%) were added to the asphalt binder by using a high speed shear mixing machine (4000 r/min) for 30 min. Since the heating of the preparation process causes some aging of the asphalt binder, it was ...

Aged Asphalt - an overview ScienceDirect Topics

The development and implementation of the Superpave binder specification has caused G ∗ to replace viscosity as the primary asphalt binder property in much of the United States. The AR calculated from G ∗, unlike that calculated from viscosity, is a function of both frequency and temperature.Because the low end of the temperature range of interest (− 10 °C) cannot be accurately measured ...

Binder Film - an overview ScienceDirect Topics

For asphalt mixtures, it has been observed that long conditioning periods can cause emulsification at the surfaces of the samples, which are in direct contact with water. In this case, water diffuses into the asphalt specimen, weakens the binder, and forms water-bitumen emulsions for asphalt binders that are unstable in water.
