Abstract: This paper presents the result of an effort to characterize asphalt emulsions that are typically used in cold in-place recycling applications using the current specifications for asphalt binders. Four asphalt emulsions ...

Abstract: The low temperature fracture properties of polyphosphoric acid (PPA) modified mixtures are evaluated and compared with those of polymer modified mixtures. The main objective is to determine whether PPA can partially or ...

Abstract: This research work investigates approaches for computing the average asphalt film thickness in asphalt mixtures and examines whether the in-place asphalt film thickness has a rational relationship with the performance of ...
