| 3 | Bio-based and nature inspired solutions: A step toward carbon-neutral economy显示文摘Bio-based and nature-inspired solutions have been investigated recently to develop sustainable,resilient,and durable construction including but not limited to roadway infrastructures.This paper reviews state-of-the-art studies on self-healing,self-cleaning and self-rejuvenating asphalt,and concrete construction.This review draws three conclusions.(1)Self-healing construction materials have the potential to significantly extend the service life of construction elements.Urban and industrial wastes such as food waste,biomass,metals have been used to create self-healing construction materials that are more environmentally friendly.(2)Self-cleaning construction materials not only remove pollution by repelling water on their superhydrophobic surface,but also cut building and infrastructure maintenance costs,while improving cities'air quality by degrading pollutants such as NOx.Pavement engineers have exploited self-cleaning characteristic to facilitate the de-icing of pavements and lengthening the service life of pavements.(3)Self-rejuvenating materials including bio-oils can revitalize materials and delay aging;bio-oils can also be used to make bio-binders,thereby reducing the need for petroleumbased binders.The optimum concentration of bio-oil for asphalt modification depends on the chemical structure of oils.Still,regardless of dosage,self-rejuvenating binders improve asphalt workability and performance at low temperatures and increase the resistance of the asphalt mix to fatigue and cracking.This review also identified critical research gaps,including(1)the lack of a reliable,unified,and standard method to accurately measure construction materials’self-healing,self-cleaning and self-rejuvenating properties;(2)the lack of longterm field performance data to conduct comprehensive life cycle assessment and life cycle analysis;(3)the lack of accurate technoeconomic analysis to facilitate market entry of abovementioned solutions.Addressing these gaps and determining contribution of nature-inspired and bio-based technologies to a carbon neutral economy along with issuing carbon certificates can facilitate the widespread application of these technologies while promoting resource conservation and sustainability. | Mohammadjavad Kazemi Hainian Wang Elham Fini | 2022 | Journal of Road Engineering2022，2，3： | 1 |

| 6 | 养生作用对硫沥青性能影响分析显示文摘硫磺部分替代传统石油沥青用于道路工程建设可减少石油沥青用量,降低施工能源消耗,促进工业废渣中硫磺的回收利用,具有较高的经济和环保价值。为探究硫磺掺量(质量分数)及养生作用对硫沥青(SEA)性能的影响,采用差示扫描量热仪(DSC)验证硫沥青中硫磺的重结晶现象,对养生前后硫沥青的基本物理性能和黏度进行分析,并采用动态剪切流变仪(DSR)和弯曲梁流变仪(BBR)对养生前后硫沥青的流变特性和疲劳性能进行评价,最后借助荧光显微镜(FM)观察养生前、后硫磺在沥青中的微观分布特性。研究结果表明:养生后高硫磺掺量的硫沥青DSC曲线出现吸热峰,硫沥青(特别是高硫磺掺量下)的劲度有所增加,因此对硫沥青进行养生使其性能稳定后再进行相关性能评价更具现实意义;硫磺掺量较低(≤10%)时,硫磺主要以溶解硫的形式存在于沥青中起到软化沥青的作用,因此沥青的低温变形能力有所改善,但其高温抗变形能力有所降低;当硫磺掺量较高(≥35%)时,硫磺主要以重结晶的形式悬浮在沥青中使沥青变硬,在增加沥青高温抗变形能力的同时也牺牲了其低温抗裂能力;硫磺掺量较低时,硫沥青黏度随着硫磺掺量的增加而降低;硫磺掺量较高时,硫沥青90℃和105℃黏度随着硫磺掺量的增加而增加,但硫沥青120℃和135℃黏度相差不大,同时硫磺加入最高可降低沥青的施工温度达20℃;线性振幅扫描(LAS)试验结果表明,养生后的硫沥青疲劳寿命比基质沥青长,其中35%硫沥青疲劳性能最佳;硫磺掺量进一步增加,硫沥青疲劳寿命缩短至与基质沥青相近;FM分析表明,硫磺掺量不高于5%时,硫磺全部溶解于沥青中,且养生后硫磺未重结晶,相应硫沥青无荧光性;硫磺掺量高于5%时,硫磺在沥青中分布均匀,养生后10%硫沥青中硫晶斑尺寸和面积显著增大,高硫磺掺量硫沥青中硫晶斑面积仅略有增加。 | 解赛楠 易军艳 冯德成 周涛 FINI Elham H | 2021 | 中国公路学报2021，34，10： | 1 |
