| Abstract: | The strength of the lime fly ash road base course materials increased a great deal when the phosphogypsum was admixed in. Their properties were modificated by the phosphogypsum. In this paper, The properties of the phosphogypsum modificating lime fly ash road base course materials such as the uncomfirmed strength, strength development, water stability and anti brushing performance were studied contracting with the lime fly ash road base course materials, the result showed that the properties of the lime fly ash road base course materials is markedly improved by phosphogypsum. |
