Experimental Study of the Effect of Early Strength Admixture on Cement Stabilized Macadam Material

Abstract:

5% cement was mixed into the cement stabilized macadam base material, then the cement was replaced by SES-I early strength admixture according to the amount of cement (mass ration) which was 0%, 8%, 10%, 12%, 14% and 16%. The unconfined compressive strength R_c of cement stabilized macadam material was tested during different curing periods 12h, 1d, 2d, 3d, 7d and 28d. Depending on the experimental date, the effect of early strength admixture on cement stabilized macadam material was investigated, and the logarithmic curve relationship can be fitted between the SES-I admixture and R_c. The experiment result shows that the 14% dosage of early strength agent is the best result for material early strength, and it also provides the foundation to increase early strength and shorten the construction period for meeting the project design demand.
