Abstract

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.

土工合成材料加固建筑与拆除材料的研究

许多研究人员建议在工程应用中使用建筑和拆除材料(C&D)而不是原始集料(VA)。然而，C&D的工程性能往往比VA差。本研究介绍了在软基上用不同类型的土工合成材料加固C&D的未铺设道路上进行的板载试验结果。作为试验的一部分，研究了土工合成材料的参数(1)埋深、(2)土工格室的高度和孔开度、(3)土工格栅的埋深和个数、(4)土工格栅之间的距离、(5)土工织物的刚度等)对非铺装道路承载力的影响。此外，同样的板载试验也在VA建造的非铺装道路上进行。研究结果表明，虽然C&D的性能不如VA，但C&D的性能足够好，可以替代VA在非铺装道路上使用。此外，在少量土工合成材料的情况下，C&D比VA具有更好的性能。

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.
