Effects of non-foaming WMA additives on asphalt binders at high performance temperatures

► We studied rheology of eight binders and four non-foaming WMA additives. ► WMA additive reduces viscosity of an asphalt binder at various test temperatures. ► Binders containing non-foam additive slightly increase high failure temperatures. ► FTIR results indicate that the binder type affects the rheology of WMA binders.
