摘要
在公路工程建设中,尤其是在公路兼顾城市道路功能的老路拓宽改造项目中,构造物回填质量是保证工程建设质量的关键。文章基于固化粉煤灰在以往工程中的应用及水泥粉煤灰试验研究成果,结合238省道镇江段拓宽改造工程实际,阐述了利用水泥粉煤灰作为构造物回填材料的技术及使用效果,以供参考。
Quality of structure backfill is important in highway engineering construction, especially in the road broaden program which has urban road function. Based on the research results of solidified fly ash in previous engineering application and experiment research, the technique and application effects of structure backfill with cement fly ash are introduced combining with reconstruction project of No. 238 provincial road Zhenjiang section, which could be taken as reference.
