浅谈骨架密实型水稳碎石配合比设计与施工

Brief Discussion on Design and Construction of Dense Framework Type Cement Stabilized Hoggin Mix Proportion

针对目前水稳配合比设计时往往忽视收缩性能的情况,提出了配合比设计时通过捣实法(最小空隙率法)调整混合料级配、设计时增加抗收缩性能试验,比较不同级配试件的抗收缩性,优化配比方案,从而得出适宜的配合比设计。

Aiming at the current situation of ignoring contractility when designing the mix proportion of cement stabilized hoggin, adjusting mixture gradation by tramping method （minimum void ratio method） in mix proportion design; adding anti - contract performance test; comparing the anti - contract performance of different gradation specimen; optimizing mix proportion scheme are put forward so that the suitable mix proportion design can be got.
