Issue: The moisture content of a fill material will affect its compaction characteristics and needs to be evaluated during quality control of the fill operation. When the fill is drier than its optimum moisture content, any moisture in the fill serves as a lubricant and helps the relative movement of the particles when densifying under vibratory compaction. When the fill is wetter than its opti...

-Compaction is one of the efficient ways to improve the strength and stiffness properties of soils, such as elasticity modulus and shear modulus. Moreover, compaction decreases soil settlement, improves bearing capacity and the stability of sloped embankments. An optimum water content is required to provide the best path to enter energy into soil and compact it. A constant value of energy appli...

Samples of apricot pits at 7.61, 12.45, 18.21 and 25.15% (wet basis) moisture contents in the three directions (along length, width and thickness) were subjected to impact energy ranged from 0.2 to 1.1 J using an impact test apparatus. Data obtained on the quantity of fully cracked and unbroken kernel, fully cracked but broken kernel and uncracked pits were used in the computation of the pits c...

We present results from an experimental study of the impact of liquid drops onto powder beds which are pre-wetted with the impacting liquid. Using high-speed video imaging, we study both the dynamics of the initial spreading regime and drainage times once the drop has reached its maximum spread on the surface. During the initial spreading stage, we compare our experimental data to a previously ...

In this paper a concept of mean particle size and size factor is presented and an attempt is made to relate the coefficient of permeability with mean particle size, keeping in view the optimum moisture content and maximum dry density. The particle size distribution has a marked impact on the coefficient of permeability. The mean particle size and the size factor can be found out from the gradat...

The green weight of southern pine tree-length roundwood delivered to the pulp mill is generally known. However, for optimum mill efficiency it is desirable to know dry weight. The moisture content of tree-length pine logs is quite variable. The moisture content of pine tree-length logs increases significantly with increasing stem height. Moisture content also varies with tree age and geographic...

Water susceptible properties of subgrade soils play important role in the structural design of highways. In this research study laboratory investigations were conducted on subgrade soil samples for determining the influence of water susceptible properties on Natural moisture content, Optimum moisture content, Compaction, California Bearing Ratio (CBR)-soaked and unsoaked, and Unconfined Compres...
