摘要
从二灰碎石基层混合料组成配比设计、控制原材料级配及含水量、调整生产配比及二次拌和、运输及摊铺中减少离析、优化压实组合以及覆盖后洒水养护等方面对其早期抗压强度进行了论述,为工程施工积累经验。
In the article many sides of the control of the early strength of base course built lime fly-ash crushed stone in construction are discussed,such that mixture composition design、control the aggregate's grade and the material's water content、adjust the proporting of mixture in construction and mix and stir twice、reduce dispersed of graded aggregate in transport and spread、choose the optimal roller compaction constitution and sprinklered maintenance after coverage.All this accumulate valuable experience for the engineering construction and give the meaning of reference.
