基于最佳含水量设计碾压混凝土配合比

Design of Mixed Rate of Rolling Compacted Concrete with Optimal Water Content

采用振碾成型测定混合料最大干容量和最佳含水量的方法进行碾压混凝土配合比设计 ,不但使设计符合现场施工情况 ,而且有效地消除了施工碾压中的弹簧问题。

The design of mixed rate of rolling compacted concrete usually does as the design method of the normal concrete, and this type of concrete is formed by vibration and compaction. The determination of reasonable mixed rate is based on simulating local construction. The design method of concrete mixed rate is introduced according to the mixed materials' biggest dry density and optimum water content obtained by vibration and compaction craft. The result shows that it combines the inner design with the outer construction, as well as avoids rebounding of roadbed during the construction.
