According to ASTM, in soil tests, the soil sample must be dried either by air or in the oven to save time, assuming that the results of the different drying methods are identical. The effect of three different degrees of drying, air drying (25 °C), oven drying (60°C, 110°C), on the physical properties of a soil sample was investigated in this study. in addition to atterberg limits, this research looks at the effect of temperature on standard compaction tests, specific weight, and granular analysis. The results show that, higher degrees of drying may result in the loss of all free water and the majority of attached water, resulting in soil restructure and a reduction in soil plasticity, especially if there is an organic content. The clay content decreases after drying due to aggregation, while the silt content increases. Drying causes a decrease in maximum dry density and an increase in optimum water content, but has no significant effect on specific gravity tests.
