FUNDAMENTALS OF SOIL COMPACTION AND

compaction. For the drop-hammer compaction, the compaction energy varied by the total nuer of blows imparted to the specimen. The nuer of blows ranged from 25 to 70; 40 blows correspond to the modified AASHO compaction energy input. For gyra­ tory compaction, the angle of gyration and the nuer of gyrations were kept at 2 deg

2013-3-28 · Factors Affecting Soil Water 1. Texture: Finer the texture, more is the pore space and also surface area, greater is the retention of water. 2. Structure: Well-aggregated porous structure favors better porosity, which in turn enhance water retention. 3. Organic matter: Higher the organic matter more is the water retention in the soil. 4.

Soil Texture and Compaction SportsField Management

2020-6-16 · The relationship between soil compaction, soil texture and root growth is shown in Table 2. This illustrates that one of the benefits of having a sandy texture is that there is still pore space when the soil is somewhat compacted. Soils with finer textures have little pore space when compacted, and root growth suffers at lower bulk densities.
