The synthesized PCU was then characterized by infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, small-angle X-ray scattering, and tensile strength measurement. The IR showed that the polymer synthesized by the above two methods both have the polycarbonate-urethane structure and the tensile measurement showed good mechanical performance of the polymer. The DSC and TGA data showed that there is an obvious soft-hard glass transition area, which indicated the existence of the micro-phase separation structure. The extent of the phase separation was affected by the ratio of starting materials, the molecular weight of PCD, and the polymerization method. The decomposition upon heating was observed in two steps. SAXS result showed that the radius (r_2), the distance between domains (d_2), and gyral radius (R_2) of hard segment micro-domain were fairly affected by the starting materials ratio and soft segment content.

Totally 60 semi-circular bending specimens cored from superpave gyratory compactor with three groups of notch depths are tested at the temperature of-10 and 20℃ The experimental results reveal good repeatability in EAM characterization. The tensile strength ratio of SCB to the indirect tensile test is at a range of 1.4 to 1.7, and the ultimate strength of EAM is exponentially dependent on the notch depths. At the test temperatures, the critical J-integral value of EAM is much higher than that of hot mix asphalt with thermoplastic asphalt binder. The response mode of EAM changes from ductile mode to brittle mode and the fracture energy increases 30% when temperature decreases from 20 to-10℃, while its critical J-integral value decreases only 15%.

Weibull distribution function is used to characterize phenomenologically the debonded probability of the interface, which is decided by the tensile stress of the particle. A partially debonded isotropic spherical elastic particle is replaced by an equivalent, perfectly bonded spherical particle, which possesses yet unknown transversely isotropic elastic moduli. The fictitious particles can be determined in such a way that their tensile and shear stresses will only vanish in the debonded direction.
