| Abstract: | In this paper, the object of study on subbase material is lime fly ash stabilized aeolian sand. Based on stability principle mechanism analysis and proportion design for lime fly ash stabilized mixture, early strength property, after mechanic property and temperature contraction property of the material are studied. Then, the law of strength rising and temperature contraction is concluded, which may provide effective refer ences for project practice. |
