Fill dirt is taken from a location where soil is being removed as a part of leveling an area for construction; it may also contain sand, rocks, and stones, as well as earth. Fill dirt should be as free of organic matter as possible since organic matter will decompose creating pockets of empty space within the fill which could result in settling ...
Compaction is accomplished by use of heavy equipment. In sands and gravels, the equipment usually vibrates, to cause re-orientation of the soil particles into a denser configuration. In silts and clays , a sheepsfoot roller is frequently used, to create small zones of intense shearing , which drives air out of the soil.

You’ve got to be kidding me. We have to be better than this, everyone. There’s too much money at stake (an estimated $800 million annually now, and possibly $1.2 billion beginning in 2026) for ...
Preconsolidation pressure is the maximum effective vertical overburden stress that a particular soil sample has sustained in the past. [1] This quantity is important in geotechnical engineering, particularly for finding the expected settlement of foundations and embankments.
U.S. President Joe Biden on Thursday said he hoped President-elect Donald Trump would rethink his plan to impose tariffs on Mexico and Canada, saying it could "screw up" relationships with close ...
A Texas teen is accused of killing a classmate’s show goat by force-feeding it pesticide. Aubrey Vanlandingham, 17, is charged with cruelty to livestock animals, a felony, according to court ...
Dynamic compaction is a method that is used to increase the density of soils when certain subsurface constraints make other methods of soil compaction inappropriate. The process involves dropping a heavy weight repeatedly on the ground at regularly spaced points, usually laid out in a systematic fashion such as a grid.
