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%.
