Description
Composite geogrids can successfully be used as a pavement-reinforcement material to increase the performance of pavement structures. This thesis presents a comprehensive study that has investigated the effectiveness of composite geogrids as subgrade reinforcement in unpaved granular pavements that are subjected to cyclic loading and constructed with local materials available in Queensland, Australia. The research outcomes suggest guidelines to design and construct unpaved granular pavements with the composite geogrid reinforcement at the base-subgrade interface. These guidelines benefit the industry by reducing construction and maintenance costs, and environmental pollution.
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.
Full-text downloads:
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
