摘要
水泥冷再生技术是一种环保型、经济型新技术,在海滨大道维修工程得以应用。从工程经济性和现场拌合、施工工艺考虑,混合料配合比设计中确定的水泥与再生混合料的比例为4∶100。在拌合场,控制水泥冷再生施工质量需要进行原材检测、级配与水泥剂量检查和含水量控制。在施工现场,通过碾压、摊铺和养生进行质量控制。检测结果表明,混合料水泥剂量、含水量和级配控制均相对稳定,能够满足施工和设计要求;现场碾压效果良好,压实度能满足施工要求。
Cement cold regeneration technology is a kind of environmentally friendly and economical new technology and has been used in the maintenance engineering of beach road. In consideration of the engineering economy, field mixing and construction technology, ratio of cement and regeneration mixture is determined in the mix design to be 4：100. The controlling of cement cold regeneration quality requires detection of the raw materi- als, inspection of grading and cement dose, and control of water content in the mixing plant. It is realized by rolling, paving and maintaining. The detection results show that the controlling of cement dose, water content and grading is good is relatively stable, and can meet the requirements of design and construction; the field compaction effect and the compaction degree can meet the construction requirements.
