| 摘 要： | 为了揭示水泥稳定碎石强度形成机理及影响因素,分别采用静压成型方法和振动试验方法成型试件,通过室内试验,研究试件成型方式、水泥剂量、级配类型和密实度对水泥稳定碎石强度的影响规律。结果表明:成型方法对试件结构尤其是矿料级配及矿料排列影响很大,振动法成型试件28 d后强度接近于静压法的2.54倍;水泥剂量(质量分数)对初始强度影响效果不明显,水泥剂量小于5%时,对水泥稳定碎石极限强度影响显著,水泥剂量超过5%时,水泥剂量增加1%时极限强度提高不超过10%;骨架密实型水泥稳定碎石比悬浮密实型初始强度约增大19%,后期强度约增大10%;试件密度提高1%,水泥稳定碎石强度至少提高11%;龄期28 d前水泥稳定碎石强度增长较为显著,龄期达到28 d时,水泥稳定碎石强度可达到极限强度的75%以上。

| Abstract: | In order to reveal the objective laws governing the strength properties of cement stabilization of crushed aggregate(CSCA),a laboratory study was undertaken to research the influence factors of unconfined compressive strength(UCS) of CSCA by using vibrating compacted specimen and static compacted specimen.The results show the UCS values of vibrating compacted specimen after 28 d of curing is 2.54 times of the one of static compacted specimen,which shows that the compacted specimen type has a strong influenc... |
