摘要
二灰土底基层是路面的重要结构物之一,已被广泛的应用于路桥施工中。从二灰土的配合比设计、拌和、摊铺碾压等多方面,阐述了表层起皮、弹簧和裂缝方面施工质量控制,探讨了二灰土易出现的质量问题,并提出了具体的质量控制措施。
As one of the most important structure of pavement, fly ash and lime subgrade has been used for the base layer in road and bridge construction. The construction quality control measures are elaborated from mix proportion design, mixing, spreading and other aspects, in view of the quality problems such as surface peeling and cracking practical quality control measures are proposed.
