compatibility  
Summary:
The primary objective of this work is to evaluate several significant factors controlling compatibility between asphalt and
synthetic polymers.  Employing NMR, FTIR, differential scanning calorimetric, dynamic mechanical spectrometry and
thermo-mechanical analysis techniques, we have determined the composition and crystallinity of representative
asphalts along with their dynamic physical properties.
