摘要
A2 标段试验段级配碎石的颗粒间孔隙率采用密度仪法和灌水法检测 ,并对 2种方法的多次检测结果进行比较 ,在压实效果达到要求的情况下 ,即使核子密度仪检测结果达不到要求 ,但采用灌水法与K3 0 相结合检测同样能满足孔隙率小于 15
By comparing results of porosity measurement of graded crushed stone by two ways for several times, a conclusion was drawn. On condition that compacting effect is available, porosity can be less than 15% as well by using hole\|watering together with K 30 testing method, even if the measuring results with nuclear density instrument can not reach compacting criteria.
