摘要
为了确保所铺设路面的质量，文章对吉怀高速所选用的50#，70#沥青和SBS政性沥青的基本性能进行了研究，结果表明这三种沥青均符合技术规范要求。采用热失重分析方法对三种沥青进行热失重分析，研究表明，在O～200℃三种沥青的质量变化不大，均小于5％，这表明这三种沥青的热稳定性比较好。另外，运用热失重分析法对三种沥青组分进行划分，并确定了沥青分解温度，以此来判断沥青稳定性的优劣。
In order to ensure the pavement quality of Jihuai expressway, the physical properties of 50#, 70# and SBS modified asphalt was studied, the results showed that the quality of the three kind of asphalt was found in conformity with the technical documentation. The thermo gravimetric analysis of 50#, 70# and SBS modified asphalt had been studied by thermo gravimetric with a weight losses were not exceeded 5% under 0-200℃, which indicated that the three kind of asphalt have good stability in high temperature.
