Hebei Expressway GroupRoad Materials Co.，Ltd.， Hengshui，Hebei Province，O532oo China Abstract： Aiming at the technical botleneck of compatibility and thermal stabilityof polymer modified asphalt，a new preparation and performance control system for polymer compositemodified asphalt has been established.A three-dimensional network structure combining physical interlocking and chemical bonding was constructed through multi-component colaborative design，staged shear dispersion，and cross-linking stabilization processes. The evolution of microstructure and rheological response patterns were systematically analyzed，and the significant improvementof thecomposite system inhighand low temperature stability，ruting resistanceand aging resistance was verified， which provides a feasible path for the engineering application of modified asphalt.

Keywords：Polymer composite modified asphalt; Croslinking stabilization; Rheological properties; Microstructure regulation

在道路工程中，聚合物改性沥青具有优异的高温抗车辙与低温抗裂性能，但其结构稳定性仍受相容性差、相分离倾向、热氧老化等因素限制，黏弹响应在宽温域内难以保持一致[1]。（剩余3638字）
