The invention provides a base-course material in which waste lime/fly ash bound macadam is stabilized by utilizing multiple inorganic curing agents. The base-course material is prepared from 60 to 100 parts of the waste lime/fly ash bound macadam, 2 to 5 parts of composite portland cement, 9 to 15 parts of slaked lime and 9 to 13 parts of water. The problems that a waste lime/fly ash bound macadam regenerated mixture is low in strength and high in shrinkage rate in the prior are solved. 本发明提供了种利用多种无机固化剂稳定旧二灰碎石的基层材料，该基层材料由旧二灰碎石60～100份，复合硅酸盐水泥2～5份，消石灰1～5份，水9～13份组成。解决了现有技术中旧二灰碎石再生混合料的低强度和高收缩率的问题。
