| 摘 要： | 为了研究粉煤灰碎石材料的疲劳性能.分别对石灰粉煤灰碎石、水泥粉煤灰碎石、水泥稳定碎石材料进行疲劳试验.结果表明,石灰粉煤灰碎石的抗疲劳性能最好,其次是水泥粉煤灰,水泥稳定碎石抗疲劳性能较差.在施工中,建议在满足强度的情况下,尽量使用石灰粉煤灰碎石.

| Abstract: | In order to investigate the fatigue performance of flyash-gravel,we conduct the fatigue test respectively with the lime-flyash-gravel,cement-flyash-gravel and cement stabilized gravel.As the result shows that,the best fatigue strength is of lime-flyash gravel,followed by cement-flyash-gravel..The cement stabilized gravel gives the poor performance.The paper suggests that,in construction,it is important to use lime-flyash-gravel as far as possible if the strength requirement is satisfied. |
