| 摘 要： | 通过系列的配合比试验，结合改性二灰基层材料的强度形成原理，建立了一套以体积分析法为基础的配合比设计方法。这种设计方法包括磷石膏改性二灰路面基层材料的结合料集料配比、石灰掺量、磷石膏掺量、粉煤灰掺量的设计以及干密度含水量等参数的确定。研究表明：按集料松堆密度计算的结合料集料比的骨架密实型路面基层材料具有较好的性能，用该方法计算的配合比与击实参数和实际值十分吻合，完全可以满足磷石膏改性二灰和二灰基层的材料设计与生产控制。

| Abstract: | A new kind of proportioning design method based on cubage analysis of phosphogypsum modification lime fly-ash road base material was brought forward through the series of test and the mechanism of its strength development.This proportioning design method of phosphogypsum modification lime flyash road base material can be used to calculate the rate of binder and aggregate, the content of lime,the content of phosphogypsum,the content of fly ash,the maximum dry density and the optimal water content.The result indicated that the binder aggregate rate detruded from apparent density had higher strength and better properties.The mixture proportion and compacting factor calculated with this method was very close to the testing data.So this method could be used to instruct the construction and quality control. |
