Abstract
Recycled concrete aggregate, that are easily found from destruction waste materials, has been used in the construction industry as an alternative for coarse aggregate components in concrete or as backfilling material in retaining structures. This paper presents the results of a study on the use of recycled concrete material in the design of a newly developed retaining wall, that is, the Geobarrier system (GBS). The GBS system was developed based on capillary barrier and vegetative cover as provisions of the sustainable construction concept. Two types of concrete aggregate are used as components of capillary barrier, that is, fine and coarse aggregate. Laboratory test result shows the recycled concrete has similar mechanical and hydraulic properties as the natural aggregate. The combination of the fine and coarse aggregates can effectively retain the water from entering the soil behind the GBS wall, therefore maintaining the negative pore pressure within the soil and therefore: the stability of the GBS.
