确定材料的最大干密度与最佳含水量的常规方法是把此类材料按重型击实标准方法求得。当粒料含量在50％以下,所得结果正确,但此方法费工费时,且当粒料含量大干50％时,常规测得结果就有误。本文为解决此矛盾,提出了含粒料半刚性基层材料最大干密度与最佳含水量快速确定法,并例举测定结果,证明与实测值基本一致。灰土结碎(砾)石和石灰粉煤灰结碎(砾)石类,混合料的最大干密度只需按式Υ_0=V_1·Υ_1+V_2·ρ计算即可,最佳含水量W_0=W_1·A+W_2(1一A);对水泥结
The conventional method of determining the maximum dry density and the optimum moisture content of a material is found by standard methods of heavy compaction. When the pellet content is below 50%, the result is correct, but the method takes time and labor, and when the content of the pellet is bigger than 50%, the routine measurement result is incorrect. In order to solve this contradiction, this paper proposed a rapid determination method of the maximum dry density and the optimum moisture content of the semi-rigid base material with pellets, and gave the results of measurement. The results are basically consistent with the measured values. Limestone knot (gravel) stone and lime fly ash crushed (gravel) stone, the maximum dry density of the mixture can only be calculated according to the formula Y_0 = V_1 · Y_1 + V_2 · ρ calculation, the optimal water content W_0 = W_1 · A + W_2 (1 a); for cement knot
