水泥混凝土路面填缝材料的研究

Research on Joint Sealants for Cemcent Concrete Pavement

对国内水泥混凝土路面填缝材料的现状做了详细的阐述,对相继出现的焦油型聚氨酯、聚氨酯、有机 硅、有机硅改性聚氨酯等填缝胶的各种性能做了系统的比较。通过综合比较,确认有机硅改性聚氨酯是比较适合中 国公路情况的填缝材料。

In this paper, developments and researches of joint sealants for cement concrete pavements are reviewed particularly and the characters of Tar-based Polyurethane,Polyurethane, Organosilicon,Polyurethane modified by organosilicon and so on sealants are compared as sealants. By the comparison, polyurethane modified by organosilicon is the better sealant fitting the cement concrete pavements of china.
