Impact of Mixing Methods and Cement Dosage on Unconfined Compressive Strength of Cement-Stabilized Macadam

Abstract The technology of vibratory mixing has been applied to improve the compressive strength cement-stabilized macadam (CSM). aim this study is investigate effect vibration acceleration and cement dosage on unconfined density CSM. mixtures with four dosages (2%, 3%, 4%, 5%) were prepared by conventional (0 g) (1 g, 2 3.5 g). was tested under different methods. And microstructure CSM analyzed scanning electron microscope. results indicate that samples using have higher strengths, lower coefficient variation, denser microstructures, compared compulsory mixing. Compared 15% in mixing, variable less than 10% method. As increase, increases. However, a more significant influence improving With increase every 1% dosage, 7-day average increased 59% 38%, respectively. maximum improvement rate UCS value 20–56.7% when from 0 1 g. Especially high, limited. Besides, reduces original over 1.6% qualified at which recommended construction practice.
