%X 基于流变学理论研究橡胶粉与不同来源基质沥青的配伍性，采用动态剪切流变仪（DSR）分别对不同基质沥青加工而成的橡胶沥青进行应变扫描、温度扫描、频率扫描等常规动态剪切流变试验，从相位角、复合模量和车辙因子等指标评价橡胶沥青黏弹特性，定性区分沥青四组分对橡胶沥青黏弹特性的影响，并对橡胶沥青进行滞回环试验，运用灰色关联数学分析方法定量给出沥青四组分对橡胶沥青的残余变形、弹性贮能、耗散能、弹性比例和复合弹性模量等指标的影响。结果表明：流变学理论是研究橡胶粉改性剂与基质沥青配伍性的有效方法；从能量角度评价沥青四组分对橡胶沥青黏弹特性指标的影响，沥青质对橡胶沥青残余应变影响较大；胶质组分对橡胶沥青弹性贮能和耗散能影响最大，而芳香分影响最小；沥青质组分对橡胶沥青弹性比例参数影响最大；芳香分含量可以提高橡胶沥青复合模量。 Rubber powder compatibility with different source matrix asphalts was studied based on the rheological theory.Using dynamic shear rheometer, the different matrix asphalts and rubber asphalts were tested by conventional dynamic shear rheological test, such as strain scanning, temperature scanning and frequency scanning.The viscoelastic properties of rubber asphalt were evaluated from the factors such as the phase angle, composite modulus and rutting factors, and the influence of the four components on the rubber asphalt viscoelastic properties was qualitative.Based on the indices such as the residual deformation, elastic energy-storage, elastic ratio and composite elastic modulus, the effects of modifying agent on the modification and viscoelastic properties of rubber asphalt were analyzed using the hysteresis loop back test specimen.The correlation was obtained by using grey correlation mathematical analysis method.The results show that rheological theory is an effective method for studying the compatibility of rubber powder and substrate asphalt.The influence of the four components of asphalt on the viscoelastic properties of rubber asphalt was evaluated from the energy angle, and the effect of asphalt on the residual strain of rubber asphalt is significant; The colloidal components can influence the elastic storage energy and dissipation of rubber asphalt, and the fragrances have the least impact; The asphaltenes have the greatest influence on the rubber asphalt elastic ratio parameters; The aromatic content increases the composite modulus of rubber asphalt. 广西科技计划项目（桂科AC16380112）
