Cement Content of Durability Cement Stabilized Macadam Base Course in Seasonal Freezing Zone
Cement content affects the performance of cement stabilized macadam base, particularly affecting its strength, and durability when the gradation is certain. To explore the influence of cement content on the performance of cement stabilized macadam base in the seasonal frozen zone, 4%–8% (1% interval) of cement were selected respectively and tested by unconfined compressive strength test, dry shrinkage test, temperature shrinkage test, and freeze-thaw cycle test based on use requirements and climatic conditions of the seasonal freezing zone. Results show that the unconfined compressive strength of cement-stabilized macadam increases gradually with the increase of cement content, and the strength increases greatly at 6% cement dosage. The dry shrinkage strain of cement stabilized macadam under different cement contents continues to increase with time. For strength and durability, 5%∼6% is the optimum cement content for the test gradation cement stabilized macadam in the seasonal freezing zone.
