几种半刚性材料的对比试验研究

Contrast Experimental Studies of Several Semi-Rigid Materials

通过对水泥砂砾、二灰碎石、二灰砂砾和二灰土等半刚性基层材料的抗压、抗冻、抗疲劳和温度收缩试验结果的分析研究,得出关于刚性基层材料路用性能的结论,为半刚性基层材料的使用提供参考。

Through analysis on semi-rigid base materials, like cement gravel, two gray gravel, two gray dust, etc, in terms of compressive strength, frost resistance, fatigue resistance and temperature shrinkage tests, this arti- cle draws a conclusion about pavement performance of semi-rigid base materials, giving some references for the use of semi-rigid base materials.
