中文摘要：

采用橡胶粉等体积代砂的方法，选择橡胶粉体积含量为5％、10％和12％，通过试验探讨了等抗压强度（40MPa）条件下橡胶粉用量对碾压混凝土力学强度、抗裂性能和变形性能的影响及其变化规律。结果表明：橡胶粉的掺入使碾压混凝土的韧性得到改善，压缩破坏表现出明显的韧性破坏特征，碾压橡胶混凝土的立方体抗压强度、轴心抗压强度、抗拉强度和抗弯强度之间具有与普通混凝土相近的对应关系；等抗压强度条件下，碾压橡胶混凝土的抗弯强度、抗拉强度和极限拉伸值较不掺橡胶粉的碾压混凝土有所增大；橡胶粉的添加不会改善碾压混凝土的干缩性能，反而会使干缩变形速率和干缩变形量有所增大。

英文摘要：

The mechanical strengths and deformation behaviors of roller-compacted rubberized concrete （RCR） were studied by keeping compressive strengths of all specimens at 40 MPa. The rubber particles were incorporated by replacing an equal volume of sand, and the rubber volume fractions were 5%, 10% and 12%, respectively. The test results show that the rigid behavior of roller compacted concrete （RCC） is improved by the addition of rubber particles, and the specimens containing tire rubber exhibit ductile characteristic during the compressive test. The relations among cubic compressive strength, axial compressive strength, tensile strength and flexural strength of RCR are similar to those of the normal cement concrete. In comparison with control concrete, the tensile strength, flexural strength and ultimate tensile elongation of RCR increase with the increase of the rubber content while their compressive strengths are kept at the same level. Unfortunately, no improvement is observed for the shrinkage behavior. On the contrary, a little increase is found in both of shrinkage velocity and total shrinkage for the specimen containing tire rubber.
