During feasibility studies for the planned 75 km long Arabian Canal project, Dubai, United Arab Emirates, the reuse of a variety of calcareous sedimentary rocks was investigated so as to inform the specification for bulk earthworks operations associated with plot development adjoining the canal route. Laboratory and field testing were undertaken through a series of large-scale earthwork compaction trials. The practicalities were investigated of compacting weak rocks at natural moisture content, taking into account that in situ moisture contents are typically dry of the optimum. With such large earthworks volumes, maximum thickness of fill layer, high productivity and consistent compaction were key considerations. Fundamental parameters controlling compaction were assessed, such as particle density, grading, and applied compactive effort, degree of saturation and final air voids, along with the performance of the fills. The results enabled the specification for the bulk earthworks to be developed making use of permissible air voids, and so permitting maximum potential for reuse of all fill types without the addition of water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
