Soil compaction

open access: yes, 2018
Project relevance: For construction of roads and embankments, soil material must be compacted to its densest state, which will result in higher soil strength and long-term stability. To obtain the compaction characteristics of soil, engineers conduct a series of laboratory standard compaction tests and then use these data for field compaction.

Subsoil Compaction: A hidden form of Soil Sealing in Europe [PDF]

open access: yes, 2001
There are two definitions of ‘soil sealing’: (I) ‘covering (sealing) the soil surface by impervious materials, e.g. concrete, metal, glass, tarmac and plastic’; and (II) ‘changing the nature of the soil such that it behaves as an impermeable medium, e ...

Combined sensor of dielectric constant and visible and near infrared spectroscopy to measure soil compaction using artificial neural networks [PDF]

open access: yes, 2014
Soil compaction is a widely spread problem in agricultural soils that has negative agronomic and environmental impacts. The former may lead to poor crop growth and yield, whereas the latter may lead to poor hydraulic properties of soils, and high risk to

Reducing deep soil compaction through strain modification under different wheel arrangements

open access: yes, 2002
New mechanisation methods associated with increasing loads have the potential to cause undesirable deep compaction, which is difficult, expensive and in some cases impossible to alleviate.

The effects of low and controlled traffic systems on soil physical properties, yields and the profitability of cereal crops on a range of soil types [PDF]

open access: yes, 2011
Soil compaction is an inevitable consequence of mechanised farming systems whose machines are degrading soils to the extent that some are considered uneconomic to repair.

Compaction effects on evaporation and salt precipitation in drying porous media [PDF]

open access: yesHydrology and Earth System Sciences, 2022
Compaction and salinization of soils reduce croplands fertility, affect natural ecosystems, and are major concerns worldwide. Soil compaction alters soil structure and affects the soil's hydraulic properties, and it therefore may have a significant ...

Study on Compaction Effect and Process of Reclaimed Soil of Nonmetallic Mines in Xinjiang, China

open access: yesAdvances in Materials Science and Engineering, 2020
Reclaimed soil is the key substrate for land reclamation and ecological restoration in the mine areas. The change of the density of reclaimed soil of the nonmetallic mines in Xinjiang during the land reclamation process was studied in this paper. Firstly,

Use of the Soil Modulus for Compaction Control of Compacted Soils

open access: yesProceedings of the International Conference on Ground Improvement & Ground Control, 2012
Insufficient compaction conditions can cause significant roadway infrastructure maintenance costs. Conventional compaction control, using nuclear methods, is based on the discrete in situ determination of the dry density and moisture content. Recently, there has been an increase interest in alternative methods for compaction control using intelligent ...

Review of manufacturers'recommendations on technological capabilities of ejectable excavator vibroplates assessment during soil compaction

open access: yesВестник СибАДИ, 2020
Introduction. Add-on compactors for excavators (ACE hereinafter) are replaceable working equipment for excavators. They are used for soil compaction after the backfill of trenches, wells, foundation cavities and other “narrow spaces” of construction, as ...
