天然气在路面工程沥青混合料加热中的应用

Application of Natural Gas in Pavement Engineering Construction for Heating of Asphalt Mixture

阐述了压缩天然气的优点,结合连霍高速公路(G30)改扩建项目,分别对采用天然气和重油加热沥青混合料进行社会效益和经济效益分析,结果表明,天然气在沥青混合料加热过程中,表现出强大的节能环保优势,同时,经济效益也大于采用重油加热方式,可为沥青混凝土路面施工加热材料的选择提供参考。

The merits of compressed natural gas are elaborated. In combination with the reconstruction and expansion project of Lianhuo Expressway（ G30）,the analyses on the social benefit and economic benefit are respectively made by adopting natural gas and heavy oil to heat the asphalt mixture. The results show that,during the heating procedure of asphalt mixture,natural gas has large energy-saving and eco-friendly advantages,and meanwhile economic benefit is also larger than that by adopting heavy oil heating mode,so as to provide reference for the selection of heating material for asphalt concrete pavement construction.
