Description
The increasing land demand challenges engineers to construct infrastructures in and on very soft ground conditions (subgrades). Therefore, it is imperative to improve the modulus and bearing capacity of these soft subgrades to allow construction machinery. This study introduced a geocomposite-embedded capping layer (gravel layer) on the soft subgrade to increase its modulus and bearing capacity by about 15 per cent and 50 per cent, respectively.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
