| Abstract: | 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. |

| Keywords: | fly ash on-site test compactness modulus of resilience deflection |
