摘　　要：磷石膏的加入大幅度改善了二灰类路面基层材料的强度性能。对磷石膏改性二灰、磷石膏改性二灰稳定粒料的强度、强度发展 ,水稳性、抗冲刷性进行了研究。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.
