水泥粉煤灰碎石基层的路用性能

Study on the performance of cement-flyash stabilized aggregate

研究了掺不同剂量粉煤灰量的水泥稳定碎石基层的路用性能,并利用扫描电子显微镜对掺粉煤灰的水泥稳定碎石的路用性能形成机理进行了分析。室内试验结果表明,粉煤灰按30%等量取代的水泥稳定碎石基层具有良好的路用性能,尤其是具有良好的抗裂性能。

Cement stabilized aggregate mixed different dosage of fly-ash were conducted in a laboratory.The test results show that cement stabilized aggregate contained 30% dosage of fly-ash has better road performance,especial anti-cracking performance.Finally,the mechanism study on the road performance of cement-flyash stabilized aggregate were conducted by use of EMS.
