摘要
沥青作为一种组成复杂的有机胶凝材料,在拌合、运输和摊铺过程中受热会释放挥发性有机化合物(Volatile organic compounds,VOCs),不仅影响周围空气质量,还可能对施工人员造成健康隐患。因此,对沥青VOCs的排放特性和抑制措施进行深入研究,是加快推进道路工程污染防治和实现绿色交通建设的重要途径之一。针对沥青VOCs的排放特性和抑制技术,围绕沥青VOCs的组分分析、影响因素和抑制技术研究,梳理了沥青VOCs的组分特征、抑制机理和抑制技术,结果表明,VOCs的释放特性未能与沥青内在组分建立联系;现有沥青VOCs抑制技术仍存在较大的改进空间,并且抑制剂对沥青及沥青混合料路用性能的影响研究有待进一步深化。
As an organic cementitious material with a complex composition,asphalt releases volatile organic compounds(VOCs)during mixing,transportation,and paving processes at high temperatures,which is undoubtedly detrimental to environmental pollution and the health of construction workers.Therefore,it is crucial to investigate the release characteristics and inhibition measures of asphalt VOCs for preventing pollution and realizing the sustainable transportation construction of pavement engineering.The component characteristics and inhibition mechanisms of asphalt VOCs were summarized by sorting out the release characteristics,influencing factors and inhibition techniques of asphalt VOCs.The results show that the release characteristics of VOCs are not related to the intrinsic components of asphalt materials.Moreover,the existing inhibition technologies of asphalt VOCs need further investigation,and researches on the influence of inhibitors on the pavement performance of asphalt and asphalt mixture need to be further deepened.
