Research on Properties of Phosphogypsum Cement Stabilized Gravel Road Base Materials
Pages: 186-190
Year: Issue:  4
Journal: Highway

Keyword:  phosphogypsumbase materialsproperties;
Abstract: A systematic discussion about factors of strength properties of phosphogypsum cement stabilized gravel is made,and the resilient modulus,splitting strength and crack resistance of such base material are studied.The results show that phosphogypsum content,cement content and aggregate gradation all have great impact on strength properties of phosphogypsum cement stabilized gravel.Compared to cement stabilized gravel,its mechanical properties grow faster,and it has good crack resistance,so it is a kind of road base materials of excellent overall performance.
