From the experimental results, the 7-day unconfined compressive strength of ordinary Portland cement-stabilized crushed stone accounts for 69.1% of its 90-day final strength, while the strength formed within 4 days for the three typical proportions of MOC-stabilized crushed stone materials reached 72.1%, 77.8%, and 82.3% of their 28 …
Performance Evaluation of Stabilized Base Course using …
Indeed, some studies have indicated that it may take up to 3 years for an asphalt-emulsion-stabilized layer to reach maximum strength (14–16). The selection of the proper additive and the correct amount to be added for stabilization has an important role in the performance properties of the stabilized layers ( 3, 4, 17 ).

Increasing the cement dosage in the cement-stabilized crushed stone recycled base layer does not significantly reduce vertical stress. Notably, a cement dosage of 4% in the recycled base layer performs better than dosages of 5% and 6%, demonstrating effective resistance to vertical stress with lower cement content. 3)
