一种含烧结脱硫灰的粉煤灰三渣路基材料
摘要：
一种烧结脱硫灰三渣路基材料，其组成及配比为：烧结脱硫灰2wt％-8wt％，粉煤灰10wt％-12wt％，石灰4wt％-10wt％，碎石70wt％-80wt％。与现有传统的粉煤灰三渣路基料相比，本发明具有如下优点：(1)烧结脱硫灰三渣路基材料7d、28d饱水无侧限抗压强度分别提高15％和80％以上；(2)烧结脱硫灰能有效改善三渣路基材料施工性能并提高抗压强度；7d抗压强度可满足高速、一级公路要求。
摘要（英）：

A three-slag roadbed material containing a sintered desulfurized ash comprises the compositions and proportions: 2 wt% to 8 wt% of the sintered desulfurized ash, 10 wt% to 12 wt% of fly ash, 4 wt% to 10 wt% of lime, and 70 wt% to 80 wt% of gravel. Compared with a conventional fly ash three-slag roadbed material, the three-slag roadbed material containing the sintered desulfurized ash has the following advantages: (1) 7 d water-saturated unconfined compressive strength and 28 d water-saturated unconfined compressive strength of the three-slag roadbed material containing the sintered desulfurized ash are respectively increased by 15% or more and 80% or more; and (2) the sintered desulfurized ash can effectively improve construction performance of the three-slag roadbed material and improve the compressive strength, and 7 d compressive strength can meet requirements of a high-speed highway and a first-class highway.
