Section through railway track and foundation showing the sub-grade. Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, [1] for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.
In transport engineering, subgrade is the native material underneath a constructed road, [1] pavement or railway track (US: railroad track). It is also called formation level . The subgrade provides support to the subbase level and acts as an integral load-bearing layer.
An embankment is a raised wall, bank or mound made of earth or stones, that are used to hold back water or carry a roadway. A road , railway line , or canal is normally raised onto an embankment made of compacted soil (typically clay or rock-based) to avoid a change in level required by the terrain , the alternatives being either to have an ...
Typical earthworks include road construction, railway beds, causeways, dams, levees, canals, and berms.Other common earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes.
The California Bearing Ratio (CBR) is a measure of the strength of the subgrade of a road or other paved area, and of the materials used in its construction.. The ratio is measured using a standardized penetration test first developed by the California Division of Highways for highway engineering. [1]

A USBR soil scientist advances a Giddings Probe direct push soil sampler.. Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is ...
