Quality Control for Fine Lime-fly-ash Macadam Spreading with Machine 

Shen Ming

   Abstract: This article analyzed processing of lime-fly-ash macadam filler through allocating, material sellection, mixture controlling, spreading and compacting mechanization, loose coefficient, thickness, water content control and segregation treatment etc. at the first stage of Outer Ring Road project. It ensured that lime-fly-ash macadam filler base could be constructed under optimal control.
