Research of the Admixture Influence Cement Stabilized Macadam Vibrating Compaction Effect

摘要

The cement stabilized macadam mixed with different admixture influence the vibration compaction effect,under certain aggregate gradation and vibration parameters,carry out vibratory compaction and compaction tests on cement stabilized macadam with incorporation of different admixture and cement dose of 4％,test results show that:when single mix water-reducing agent,adding 1.0％,cement stabilized macadam most easily compacted; when single mix fly ash,the mixing 30％,cement stabilized macadam most easily compacted; when compound mixed with fly ash and water-reducing agent,help reduce optimum water content,increasing the maximum dry density compared with single mix water-reducing agent or fly ash,and water-reducing agent dosage is 1.0％,fly ash dosage is 20％ are the best.
