Investigation of the construction and demolition materials reinforced by geosynthetics
Many researchers suggest using construction and demolition materials in engineering applications (C&D) rather than virgin aggregates (VA). However, the engineering properties of the C&D tend to be poorer than those of the VA. This study presents the results of plate loading tests performed on unpaved roads with the C&D, reinforced by different types of geosynthetics on the soft subgrade. As part of these tests, the effects of some geosynthetics’ parameters such as (1) the embedment depth, (2) height and pocket opening of geocell, (3) the embedment depths and number of geogrids, (4) the distance between geogrids, and (5) the stiffness of geotextile on the bearing capacity of the unpaved road were investigated. Besides, the same plate loading test was also conducted on an unpaved road built by the VA. As a result of this study, although the performance of the C&D was determined to be less than that of the VA, it was concluded that the C&D performed well enough to be used as an alternative to the VA on unpaved roads. Besides, with a very small number of geosynthetics, it was determined that the C&D could have a better performance than that of the VA.
期刊介绍：
Engineering Sustainability provides a forum for sharing the latest thinking from research and practice, and increasingly is presenting the ''how to'' of engineering a resilient future. The journal features refereed papers and shorter articles relating to the pursuit and implementation of sustainability principles through engineering planning, design and application. The tensions between and integration of social, economic and environmental considerations within such schemes are of particular relevance. Methodologies for assessing sustainability, policy issues, education and corporate responsibility will also be included. The aims will be met primarily by providing papers and briefing notes (including case histories and best practice guidance) of use to decision-makers, practitioners, researchers and students.
