Analysis on Influencing Factors of Cement Stabilized Macadam Base of Compressive Strength in Shenyang Area

Abstract:

The compressive strength of cement stabilized macadam base is an important index to evaluate the quality of road construction. In this paper, investigation and field sampling were conducted on roads in Shenyang city, and, indoor experiment study was then adopted to analyze effects of particle grade, cement dosage, molding method, compaction and curing age on compressive strength. The results show that rational particle grade greatly enhances the strength. Strength of vibration molding sample is closer to the field sample strength and is 0.6 times bigger than that of static pressure molding sample. 1% increment of construction compaction degree will induce 10% increment of compressive strength. Increment of cement dosage and curing age will induce increment of compressive strength, but the effect is limited. Studied in paper can provide a theoretical basis for site construction in Shenyang area.
