construction terminology

Subgrade refers to the soil or material that is prepared to support a structure, typically the base of a road, railway, or pavement. It is the underlying layer beneath the pavement that distributes the load to the subsoil. Proper compaction and treatment of the subgrade are critical for the stability and durability of the structure above.

Synonyms

base layer, foundation, subsoil

Examples of usage

  • The engineers tested the subgrade for compaction.
  • We need to improve the subgrade before laying the asphalt.
  • Water drainage is essential to maintain the quality of the subgrade.

Etymology

The term 'subgrade' emerges from the combination of two words: 'sub,' which originates from the Latin prefix meaning 'under,' and 'grade,' derived from the Latin 'gradus,' meaning 'step' or 'degree.' Together, 'subgrade' represents the idea of a supportive layer that lies beneath a certain level. The use of the term can be traced back to the early 20th century, coinciding with advancements in civil engineering and construction practices. As urbanization increased, the importance of proper groundwork became evident, leading to the formalization of terms like subgrade to describe the various layers in construction. The understanding of soil mechanics and its role in structural integrity further solidified the relevance of this term in civil engineering vocabulary.
