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: Most studies addressing the use of recycled asphalt materials in asphalt paving mixtures are based on experimental tests and performance evaluation. Investigating the effect of adding recycled materials to the microstructure ...

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: Two methods are proposed to correct stresses measured with the thermal stress restrained specimen test (TSRST) due to specimen bending. The first method estimates the bending stress from the angle of rotation of the specimen ...

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 ...

Abstract: An investigation of various factors that can affect the fracture resistance of asphalt mixtures at low temperatures was conducted. The fracture resistance of 28 asphalt mixtures—which represent a combination of factors ...
