摘　　要：根据大量水泥稳定再生骨料抗压回弹模量试验,考察了养护龄期、水泥用量、再生骨料来源及取代率对抗压回弹试验结果的影响。试验数据分析表明,再生骨料的掺加对水泥稳定混合料的抗压回弹模量有明显的增强效果,且在同等再生骨料取代率水平下,随着水泥用量和龄期的增长,抗压回弹模量不断增大,且再生骨料来源的混凝土强度越高,试验测得的抗压回弹值越大。Based on plenty of the compressive resilient modulus test results of cement stabilized recycled aggregate, some effect of curing periods of specimens, cement content, sources of recycled aggregate and replacement ratio on the compressive resilient modulus are studied. The study resuks indicate that the addition of recycled coarse aggregate can obviously enhance the compressive resilient modulus of cement stabilized macadam. Under the same condition of the re- placement ratio of recycled aggregate, there is an increase tendency of compressive resilient modulus with increasing of cement content and curing period. And the higher the strength of concrete with recycled aggregate is, the larger the com- pressive resilient modulus got by the test is.
