Pavement Performance of Low Dosage Cement Stabilized Gravel Powder Mixed with Aggregates

Abstract

On the basis of test analysis, mix design of cement stabilized gravel powder, cement stabilized gravel powder mixed with 20% aggregates and cement stabilized gravel powder mixed with 40% aggregates were compared, their unconfined compressive strength were tested, and the mixed aggregates ratio and mix design were ultimately determined. The experimental results show that mixing a certain amount of aggregate can reduce cement dose and meet the design strength. Engineering project cost by mixing with a certain amount of aggregate was little higher than that of cement stabilized gravel powder. Comprehensively considering technical and economic factors, the recommended amount of aggregates mixed with 30% and cement dose of 2%.
