Microstructural transformation of a poly(styrene-b-butadiene-b-styrene), SBS, triblock copolymer blended with asphalt was studied as the asphalt composition was varied from 0 wt% to 96 wt%. Transmission electron microscopy (TEM), dynamic mechanical spectrometry (DMS), and differential scanning calorimetry (DSC) were used. The blends were made in batch mixers at 200 [degrees] C, or by solution casting from a nonselective solvent (trichloroethane) at [approximately]28 [degrees] C. Asphalt parti...
