<p>In<?tk 2?> regions that experience seasonal freezing, conventional mixing methods for cement-stabilized soil (CSS) often result in insufficient material uniformity, leading to strength variability and reduced durability. This study examines how vibration mixing and conventional mixing affect the mechanical properties, freeze-thaw resistance, shrinkage behavior, and internal homogeneity of CSS with a cement content of 10%. At curing ages of 7, 14, and 28 days, specimens were tested for unconfined compressive strength, splitting tensile strength, and flexural strength under both room-temperature (25&#xa0;°C) and low-temperature (− 18&#xa0;°C) conditions. The coefficient of variation (<i>C</i>_<i>v</i>) was employed to evaluate the influence of mixing technique on the internal uniformity of CSS. In addition, freeze-thaw resistance, dry shrinkage, and temperature-induced shrinkage tests were conducted to assess material durability. The results demonstrate that vibration mixing significantly enhances the mechanical performance of CSS. Compared with conventional mixing, the unconfined compressive strength at a curing age of 7 days increased by 13% under room-temperature conditions and by 79% under low-temperature conditions. The splitting tensile strength increased by up to 29.4% at a curing age of 7 days, while the flexural strength improved by 17.9% at 14 days. In addition, the <i>C</i>_<i>v</i> of strength decreased by 57% at 28 days, indicating a substantial improvement in internal uniformity. Vibration mixing also effectively reduced strength degradation after freeze-thaw cycling and lowered both dry shrinkage and temperature-induced shrinkage coefficients by more than 30% for specimens cured for 28 days. The findings provide practical insights into optimizing mixing techniques for cement-stabilized subgrade materials, thereby improving the durability and service life of pavement structures exposed to harsh environmental conditions.</p>
