  • The maximum dry density and optimal moisture content of soil are key indicators of compression, shear and penetration in earthwork. Based on the Malan loess in Jingyang area, compaction curves of reused soil and non-reused soil are contrasted and analyzed through the indoor standard compaction test, and the paper presents the method of using three-point two-time interpolation function to establish the functional relation between the maximum dry density and the optimum moisture content so as to indicate the reliability of the compaction test results. The research indicates that the optimum water content of Malan loess in Jingyang area is 17.07% and the maximum dry density is 1.735g cm-3. The optimum water content and the maximum dry density of reused soil are 1.762g cm-3 and 16.69%,respectively. Compared with non-reused soil, the maximum dry density increased by 1.56% and the optimal water content decreased by 2.23%.The conclusion obtained by using the three-point two-time interpolation function is basically consistent with the compaction test, which shows the accuracy of the compaction test. The method has the advantages of clear thinking and simple calculation, and has high applicability, which provides a theoretical basis for solving the maximum dry density and the optimal water content.
