摘　　要：援建巴布亚新几内亚(以下简称“巴新”)“独立大道”项目,为双向六车道,总长约1.06km,其道路两侧设有人行道,为现浇水泥混凝土形式,设计宽度为5m,总长2120m.对于道面的抗滑构造工艺,巴新普遍是在混凝土处于塑性状态时,利用硬质扫把将表层进行拉毛处理,效果不佳.为了改观人行道的外观质量,提高工程的总体效果,文章将重点对细毛压槽新工艺在人行道施工中的应用做全面介绍.The"independent Avenue"project of aiding the construction of Papua New Guinea(hereinafter referred to as"Papua New Guinea")is a two-way six lane project with a total length of about 1.06 km.Sidewalks are set on both sides of the road in the form of cast-inplace cement concrete with a design width of 5 m and a total length of 2120 m.As for the anti-sliding construction technology of pavement in Papua New Guinea,generally,when the concrete is in the plastic state,the surface layer is roughened by hard broom,and the effect is not good.In order to improve the appearance quality of the sidewalk and improve the overall effect of the project,this paper will focus on the application of the new technology of fifine wool pressing groove in sidewalk construction.
