摘要
二灰碎石作为各类公路的基层和底基层已是普遍现象。而安徽淮南地区粉煤灰资源又十分丰富。通过不同场合多次取样检测和试验室验证对比,发现采用不同比表面积的粉煤灰(按同一的配合比要求进行配比)对二灰碎石的无侧限抗压强度有明显的影响,同时消除了许多认识误区,如粉煤灰的存放时间、干湿状态对二灰碎石的强度影响等。
It is a common phenomenon that lime-fly-ash stabilized-aggregates acts as the base and subbase of highways. Huainan has rich resources of flyash. By sampling in different situation and tom-paring the result with indoor result,the text comes to a conclusion that flyash with various specific surface area （matching at the same mixture ratio） has a great influence on unconfined compressive strength of lime-fly-ash stabilized-aggregates and meantime clear up some cognitive mistakes.
