Abstract: This paper presents an image-based testing system called the asphalt foam collapse test (AFCT) to measure parameters that indicate the quality of foamed warm mix asphalt (WMA) binders. The AFCT was used to measure and ...

Abstract: Foam-based Warm Mix Asphalt (WMA) technologies decrease the viscosity of the asphalt so that it is workable during construction. However, after construction, viscosity increases rapidly as the foam disappears and temperature ...
