摘要

研究重点是评估在热拌沥青(HMA)生产中使用微波辐射作为再生沥青路面(RAP)替代加热方法的潜力。最近关于微波辐射在道路工程中应用的研究大多集中在裂缝沥青路面上。在这项研究中,根据含有不同水分的不同 RAP 含量的 HMA 的物理和机械特性对微波加热性能进行了评估。试验结果与含有大量 RAP 和苯乙烯-丁二烯-苯乙烯(SBS)聚合物改性粘结剂的 HMA 进行了比较。测试结果证实了利用微波加热 HMA 而不会对其基本特性产生不利影响的可能性。研究还显示了在 HMA 生产过程中加热 RAP 的可能性,特别是当 RAP 的水分含量超过 3% 时。此外,在使用湿 RAP 生产 HMA 的情况下,对 HMA 的测试并未发现微波加热会产生任何负面影响。通过比较两种 HMA 在微波影响下的表现,可以看出 SBS 聚合物对微波辐射的敏感性。在相同的微波加热时间内,含有改性沥青的 HMA 似乎比未改性沥青的 HMA 温度更高。

Analysis of Reclaimed Asphalt Pavement Heating with Microwave Radiation

Analysis of Reclaimed Asphalt Pavement Heating with Microwave Radiation

The research focuses on the assessment of the potential use of microwave radiation as alternative heating method for reclaimed asphalt pavement (RAP) in hot mix asphalt (HMA) production. Recent studies on the use of microwave radiation in road engineering mostly focused on the cracked asphalt pavement. In the study, microwave heating performance was assessed based on the physical and mechanical characteristics of HMA with different RAP contents containing various amount of moisture. Results were compared to the HMA consisting of high amount of RAP containing Styrene–Butadiene–Styrene (SBS) polymer modified binder. The test results confirmed the possibility of microwaves utilization in order to heat the HMA without adversely affecting its basic properties. The research also shows the possibility of heating RAP in the process of HMA production, especially if the RAP moisture level is above 3%. In addition, the tests on HMA did not reveal any negative impact of microwave heating in the case of using wet RAP for the production of HMA. The susceptibility of the SBS polymer to microwave radiation was indicated by comparing the behavior of the two HMA types under its influence. HMA containing modified bitumen appears to achieve higher temperatures than HMA with unmodified bitumen after the same time of microwave heating.
