摘　　要：粉煤灰是煤在生产利用过程中产生的工业固体废物,处置不当不仅会污染环境,还会占据大量土地资源。目前,粉煤灰的资源化利用主要包括改良土壤、制作肥料以及制造建材。已有研究表明,粉煤灰在道路工程中具有良好的应用前景。为显著提高粉煤灰的利用率,急需开展粉煤灰在道路工程中的应用研究。对已有研究成果进行综述是进一步深入研究的前提。本文结合粉煤灰的物化性质,综述粉煤灰在道路工程中的应用研究现状及应用方法,指出目前研究存在的不足,并提出进一步研究的建议与展望,为粉煤灰在道路工程中的资源化利用提供参考。Fly ash is an industrial solid waste generated during the production and utilization of coal,improper disposal not only pollutes the environment,but also occupies a large amount of land resources.At present,the resource utilization of fly ash mainly includes improving soil,making fertilizers,and manufacturing building materials.Previous studies have shown that fly ash has good application prospects in road engineering.In order to significantly improve the utilization rate of fly ash,it is urgent to carry out research on the application of fly ash in road engineering.A review of existing research results is a prerequisite for further in-depth research.Based on the physicochemical properties of fly ash,this paper summarizes the current research status and methods of its application in road engineering,points out the shortcomings of current research,and proposes suggestions and prospects for further research,thus providing reference for the resource utilization of fly ash in road engineering.
