沥青是多种有机化合物的复杂混合物,其粘弹性质在许多方面与低分子量聚合物相似,强度和变形性能与温度有很大关系。温度升高时,沥青粘滞度降低、强度变小、变形性能增大,容易流淌;温度降低时,沥青粘滞度增大、强度变大、变形性能减小、变硬而且发脆。人们为了改进沥青材料的性质采取了许多方法和途径,在沥青中加入橡胶类高分子聚合物,是 Asphalt is a complex mixture of many organic compounds, and its viscoelastic properties are similar to low molecular weight polymers in many aspects, and strength and deformation properties are closely related to temperature. When the temperature rises, the viscosity of the asphalt decreases, the strength decreases, the deformation performance increases, and the flow easily occurs. When the temperature decreases, the asphalt viscosity increases, the strength increases, the deformation performance decreases, and the asphalt becomes brittle. In order to improve the properties of asphalt materials, people have taken many methods and approaches. Adding rubber-based macromolecular polymers to asphalt is
