| 摘 要： | 通过室内试验测试了两种集料级配下，乳化沥青用量分别为7％、8％、9％，水泥用量分别为2％、3％、4％时水泥乳化沥青混凝土的物理、力学性质。试验结果表明：在乳化沥青含量不变时，随着水泥用量的增加水泥乳化沥青混凝土的马歇尔稳定度、抗压强度、抗折强度、抗压回弹模量、抗折回弹模量随之增加；在水泥用量不变时，随着乳化沥青用量的增加相应的力学指标呈降低趋势；矿料级配中粗集料含量增加后，混合料的抗折强度和抗折回弹模量有明显增加，但抗压强度和抗压回弹模量变化不大。

| Abstract: | Laboratory tests were carried out on two aggregate gradings with asphalt content of 7%, 8% and 9%, and with cement content of 2%, 3% and 4% respectively.The result indicates that in the case of constant content of asphalt, Marshall stability, compression strength, rupture strength, compression modulus and rupture modulus of cement emulsified asphalt concrete would increase along with the increase in cement content; in the case of constant content of cement, these index values would decrease along with the increase in asphalt content; while with the increase of coarse aggregate, rupture strength and rupture modulus of the concrete would increase conspicuously, yet compression strength and compression modulus would have a little change. |
