- Abstract:
- The performance evaluation and chemical property analysis of the recycled warm mix asphalt(RWMA)binders containing 100% artificial reclaimed asphalt(RA)are presented, and the combined effects of different percentages of the rejuvenator and warm mix additive(WMA)additives on RWMA binders are analyzed through laboratory tests. Three types of WMA additives and one commercial rejuvenator named GST were selected to restore the artificial RA. The laboratory performance tests including the penetration test, softening test and rotary viscosity(RV)test were carried out. In addition, the Fourier transform infrared spectroscopy(FTIR)test was performed to explore the chemical property of RWMA binders. The results of the performance tests indicate that the rejuvenator GST has the ability to restore the artificial RA; choosing the optimum content of WMA additives and rejuvenator is the key to restoring 100% artificial RA, since the combined effects of them play an important role in determining the basic laboratory performance of RWMA binders. The FTIR tests show that the process of recycling mainly adjusts the chemical component of aged asphalt and no remarkable change is observed in the FTIR spectra of RWMA binders in terms of chemical functional groups with the introduction of WMA additives.
- 通过试验分析不同比例的再生剂和温拌剂对于温拌再生沥青的共同作用, 对含有100%人工老化沥青的温拌再生沥青的性能与化学特性进行了分析评价.选用3种温拌添加剂与1种商业再生剂GST来再生人工的老化沥青.再生结合料的性能试验包括针入度、软化点以及旋转黏度试验, 傅里叶红外光谱试验则用来探讨再生结合料的化学特性.性能试验结果表明, 再生剂GST具有再生人工老化沥青的能力;由于再生剂与温拌添加剂的共同作用对于100%老化沥青的再生性能有很大的影响, 因此选择两者的合适用量是再生100%老化沥青的关键.红外光谱试验结果表明, 再生主要是一种调节化学组分的过程, 而且随着温拌添加剂的加入, 温拌再生沥青的红外谱图在化学官能图方面并没有发生明显的变化.
