Asphaltic binders highly modified with two incompatible polymers, a Styrene Butadiene Styrene triblock copolymer and an Atactic Polypropylene were studied. Using UV fluorescence reflexion microscopy it was shown that natural segregation of the polymers occurred in the binders and in order to obtain maximum effectiveness of both polymers there was an optimum in the polydispersity and mean value of the particle size distribution of the swollen SBS polymer. The fineness of the dispersion of the polymers and the cohesion at the asphalt/polymer phase were highly dependent upon the chemical composition of the asphalt.
