Visualization and quantification of soil laboratory impact compaction

Journal of Rock Mechanics and Geotechnical Engineering, 2022
As important methods to guide the field soil compaction, the standard and modified Proctor tests for laboratory compaction have remained unchanged for decades, which should be improved to better understand the compaction process and the properties of ...

Lime stabilisation for earthworks: a UK perspective [PDF]

, 2014
Lime stabilisation is a versatile technique applied during earthworks operations. Modern soil recycling units are much more efficient at pulverising fill material and intermixing the added binder/water than machinery available 20 years ago.

Compaction behaviour of clay [PDF]

, 2008
This paper presents an experimental study of the compaction behaviour of non-active clay. One-dimensional static compaction tests were carried out at high and medium water content with matric suction monitoring using Trento high-capacity tensiometers. At

Effect of compaction pressure on consolidation behaviour of unsaturated silty soil [PDF]

, 2004
The effect of compaction pressure on subsequent soil behaviour during isotropic consolidation has been investigated by conducting controlled-suction triaxial tests on samples of an unsaturated compacted silty soil.

Importance of controlling the degree of saturation in soil compaction [PDF]

, 2016
n the typical conventional fill compaction, the dry density ρd and the water content w are controlled in relation to (ρd)max and wopt determined by laboratory compaction tests using a representative sample at a certain compaction energy level CEL ...

Soil compaction

, 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.

Root anatomical traits contribute to deeper rooting of maize under compacted field conditions [PDF]

, 2020
© The Author(s) 2020. To better understand the role of root anatomy in regulating plant adaptation to soil mechanical impedance, 12 maize lines were evaluated in two soils with and without compaction treatments under field conditions.

Compaction conditions greatly affect growth during early plant establishment [PDF]

, 2017
Successful plant establishment is critical for the success of store/release cover systems. Such cover systems comprise several soil layers: highly compacted lower layers to isolate the waste; and nominally-loose upper layers to support vegetation ...
