We must take account of crack resistance when doing mixture design . after systematic and scientific determination and analysis of temperature contraction property , aridity contraction property and strength index , the thesis have chosen the best grade limits in which crack resistance and compressive strength are high . this conclusion is based upon standard ? grade limits of cement stabilizing crushed stones subbase 本課題在對水泥穩定類材料溫縮、干縮性能以及強度和模量等指標的測試分析前提下，以規范原有的水泥穩定碎石基層級配范圍為基礎，選擇出抗裂性和抗壓強度兩項指標俱佳的級配范圍。
Because the best grade limits does not vary with material property , firstly , we can confine material grade to the best grade limits when doing subbase mixture design , secondly , after systematic temperature contraction test , aridity contraction test and compressive strength correction test , we can determine the best cement percentage which has the best crack resistance property 因為最佳級配范圍是與粒料的粒徑大小有關的，所以在基層材料配合比設計時可首先將材料級配限制在最佳級配范圍以內，然后通過系統的溫縮、干縮性能試驗以及抗壓強度校核試驗，最終確定抗裂性較好的合理水泥劑量。
We can use both calcium carbide dust and calcium carbide dust - flyash to stabilize fine - soil . as well as being used in subbase of high grade road , calcium carbide dust stabilization and calcium carbide dust - flyash stabilization can be used in basecourse of low grade road . so we can deduce that calcium carbide dust - flyash - gravel stabilization can be used in basecourse of high grade road 我們可以利用電石灰來穩定細粒土，利用電石灰和粉煤灰來穩定細粒土。通過數據分析，這種電石灰穩定土和電石灰二灰土完全可以剛于高等級公路的高級路面的底基層，也可以用于低等級公路的路面基層，同時推斷，用電石灰和粉煤灰來穩定的級配碎石，可用于高等級公路的路面基層。
