摘　　要：目前,贫混凝土作为路面基层材料得到越来越多的应用。文章通过室内试验,得出振捣贫混凝土与碾压贫混凝土的28d弯拉强度与抗压强度,分析了水泥用量、粉煤灰掺量等因素对贫混凝土强度的影响规律,并根据试验结果得出贫混凝土弯拉强度与抗压强度的相关关系。Nowadays,lean concrete has been more and more widely used as the base course material of pavement.After laboratory test,the Paper derives the 28d flexuraltensile strength and compression strength of vibrated lean concrete and rolled lean concrete,and analyzes the rule of how the cement dosage and flyash quantity affect the lean concrete strength.Based on the test result,it also elicits the relationship between the flexuraltensile strength and compression strength of lean concrete.

关 键 词：道路工程 贫混凝土 弯拉强度 抗压强度
