摘要
阐述了试验原材料的选择以及低温粘度和玻璃化温度的测试方法,并选择了三种不同标号的沥青及掺量为5%SBS改性沥青,测定了其-10℃、0℃、10℃粘度及玻璃化温度,通过分析对比,评价了SBS改性沥青的低温性能。
The article describes how to select raw materials and the test methods for low temperature viscosity and glass transition temperature. Three different grades of asphalt and modified asphalt adding 5% SBS are chosen,and measures their- 10 ℃,0 ℃,10 ℃viscosity and glass transition temperature. Through analysis and comparison,low temperature performance of SBS modified asphalt is evaluated.
