SBS改性沥青热储存过程中软化点衰减机理分析

Research on the Softening Point Decreasing Mechanism of SBSModified Asphalt during Hot Storage

对多种 SBS改性沥青热储存过程中软化点变化进行了试验 ,发现软化点的衰减虽然是 SBS改性沥青的共性 。

The softening point decreasing mechanism of SBS modified asphalt during its hot storage was studied and the result show that the decreasing behavior bears much relation to the properties of base asphalt even though this phenomena occurs in all types of SBS modified asphalt.
