Abstract
This paper presents the laboratory investigation of properties of warm mix asphalt (WMA) binders and WMA binders containing
polyphosphoric acid (PPA).Two types of warm mix additives were used to produce the WMA binders. Superpave tests were carried
out on original and short-term aged binders through the rotational viscometer, the dynamic shear rheomet
