Embankment (earthworks)
This article needs additional citations for verification. (October 2021) |
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
cutting
is used for the same purpose where the land is originally higher than required.
Materials
Embankments are often constructed using material obtained from a cutting. Embankments need to be constructed using non-aerated and waterproofed, compacted (or entirely non-porous) material to provide adequate support to the formation and a long-term level surface with stability. An example material for road embankment building is sand-bentonite mixture often used as a protective to protect underground utility cables and pipelines. [1]
Intersection of embankments
To intersect an embankment without a high flyover, a series of tunnels can consist of a section of high
abutments for a bridge
.
