翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Subgrade ： ウィキペディア英語版 Subgrade In transport engineering, subgrade is the native material underneath a constructed road,〔http://www.highwaysmaintenance.com/drainage.htm The Idiots' Guide to Highways Maintenance ''highwaysmaintenence.com''〕 pavement or railway (US: railroad) track. It is also called formation level. The term can also refer to imported material that has been used to build an embankment. ==Construction== Subgrades are commonly compacted before the construction of a road, pavement or railway track, and are sometimes stabilized by the addition of asphalt, lime, portland cement or other modifiers. The subgrade is the foundation of the pavement structure, on which the subbase is laid. The load-bearing strength of subgrade is measured by California Bearing Ratio (CBR) test, falling weight deflectometer backcalculations and other methods. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Subgrade」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
