降粘剂Sasobit对温拌沥青的性能影响与评价

降粘剂Sasobit是可实现沥青混合料温拌化的一种新型材料。通过对掺有降粘剂Sasobit沥青的常规性能、流变性能和粘度指标测试,分析降粘剂Sasobit掺入前后的沥青性能变化及其掺量影响。结果表明,降粘剂Sasobit可显著提高沥青高温性能,对低温性能略有降低。降低沥青高温粘度,提高低温粘度,可实现沥青混合料的温拌化,且其最佳掺量为2%

Evaluation on the Performance of Asphalt with Sasobit

Sasobit additive is a new type of material that it can realize warm asphalt mixture.Paper analyze on performance changes and quantity affect of asphalt with viscosity Sasobit by convention performance and rheological behaviour and viscosity.Results show that viscosity Sasobit can significantly improve the high temperature performance of asphalt and a slightly lower temperature properties.The viscosity Sasobit reduce high viscosity and improve low viscosity that realize warm asphalt mixture and the best admi...
