摘　　要：通过现场碾压试验,研究粉煤灰用于路堤填料的工程性状。现场压实试验测试项目包括高程测量和压实度、承载板、弯沉测试。试验结果表明,只要控制好粉煤灰的含水率、摊铺厚度和压实工艺,粉煤灰路堤的压实度、回弹模量、弯沉量等指标完全能够满足规范要求。Based on rolling compaction test on site,this paper studies engineering properties of fly ash used as embankment filling.On-site compaction test items include elevation measurement and test of compactness,loading plates and deflection.Test results show that if only moisture content,paving thickness and compaction technology of fly ash are well controlled,indices of fly ash embankment such as compactness,modulus of resilience and amount of deflection,etc.can fully satisfy the requirements of specification.
