| 摘 要： | 本文提供了由试验研究得出的自密实道面混凝土弯曲疲劳方程，并与干硬性道面混凝土进行了对比。认为自密实道面混凝土具有较好的抗疲劳特性。用图表示了在弯曲应力重复作用下，试件小梁跨中底部弯拉应变累积过程，包括平稳累积过程和应变快速增长直至试件断裂的过程。初步得出道面混凝土极限弯拉应变在200με左右。

| Abstract: | Flexural fatigue equation for self-compacting pavement concrete is established through experimental investigation,and is compared with dry concrete.It is found that fatigue behavior for self-compacting pavement concrete is better.The figure expresses the process of cumulative flexural strain of specimen beams bottom in terms of action of cyclic flexural stress,and includes the stage that strain smoothly accumulating and the stage that strain quick increasing until specimen beams fracture.The result is that the limiting flexural strain for self-compacting pavement concrete is about 200. |
