99) as the method of estimating maximum dry density and optimum moisture content for subgrades and compacted fill sections. The standard Proctor test approximates maximum soil density capable. The maximum achievable density depends on the type of material, as well as the input energy during compaction. It is commonly used for diatomaceous earth and halyositic clays. Average maximum dry unit weight and optimum moisture content achieved by standard Proctor Tests (ASTM D698) with plastic limit (PL) and liquid limit (LL). This is a key figure to consult when compacting expansive clay.

METHOD A7 THE DETERMINATION OF THE MAXIMUM DRY DENSITY AND OPTIMUM MOISTURE CONTENT OF GRAVEL, SOIL AND SAND SCOPE The maximum dry density and optimum moisture content, as defined below, is. Determine the Maximum Dry Density and the Optimum Moisture Content of Soil This test is done to determine the maximum dry density and the optimum moisture content of soil using heavy compaction as per IS: 2720 (Part 8) – 1983.The apparatus used is i) Cylindrical metal mould – it should be either of 100mm dia. and 1000cc volume or 150mm dia. and 2250cc volume and should conform to IS: 10074.

density is expressed in terms of the dry density of the minus Вѕ in. (19 mm) portion of the material. The method of determining the control density is described in Section 5.2..

Such a higher maximum index density, when considered along with the minimum index density/unit weight, Test Methods D4254, will be found to significantly affect the value of the relative density (3.2.8) calculated for a soil encountered in the field. While the dry method is often preferred because results can usually be obtained more quickly, as a general rule the wet method should be used if. The laboratory testing is meant to establish the maximum dry density that can be attained for a given soil with a standard amount of compactive effort. In the test, the dry density cannot be determined directly, and as such the bulk density and the moisture content are obtained first to calculate the dry density as , where = bulk density, and w = water content.

METHOD A7 THE DETERMINATION OF THE MAXIMUM DRY DENSITY AND OPTIMUM MOISTURE CONTENT OF GRAVEL, SOIL AND SAND SCOPE The maximum dry density and optimum moisture content, as defined below, is The minimum densities obtained by using the ASTM Test for Relative Density of Cohesionless Soils (D 2049-69) were considerably higher than those obtained by using several other simple procedures. Acceleration appeared to be the most important vibration parameter, and accelerations greater than the optimum acceleration (the acceleration at which the maximum density of a soil was obtained
