“…There is however an increasing impetus from state government sustainability initiatives to use recycled C&D materials where appropriate, particularly as construction materials in civil engineering infrastructure. In Australia,8.7 million tons of recycled concrete aggregate (RCA) and 1.0 million tons of Fine Recycled Glass (FRG) are stockpiled annually [9]. RCA is commonly obtained from C&D activities while FRG is produced from the glass component of household waste collections.…”

“…Direct Shear Tests (DSTs), conducted by Soból et al [24] and Arulrajah et al [25], showed that among six tested C&D materials all meet the shear strength requirements for aggregates in pavement engineering, including RCA. Melbouci [26] in 2009 carried out cyclic loading tests on RCA samples with addition of sand and concrete.…”

Featured Application: Recycled Concrete Aggregate can be a very good alternative material for natural aggregate. Using soil-rubber mixture as an engineering material may not only provide alternative means of reusing waste but also significantly change dynamic properties of soil.Abstract: This paper discusses the application of piezoceramic bender elements (BEs) for measurement of shear wave velocity in the time and frequency domain in a triaxial cell under different isotropic confinement. Different interpretation methods were used in the tests and their results were finally compared with each other. Two types of anthropogenic material were tested: pure Recycled Concrete Aggregate (RCA) and RCA-rubber chips mixtures (15% of rubber addition). Presented study is an attempt to describe dynamic properties, in terms of shear wave velocity (V S ), of the aforementioned anthropogenic material using the technique commonly applied for natural soil. Although some research is currently being carried out, in order to evaluate physical, chemical and mechanical properties of RCA and rubber-soil mixtures, still little is known of their dynamic properties. Hence, this work will provide the experimental results of shear wave velocity of RCA and its modified version. The results show that tires chips significantly decrease the V S values of modified RCA. They help to reduce the near field effect, but the received parameters are more incoherent. The V S values were found to be influenced by interpretation technique, mean effective stress and wave's propagation period. The maximum V S values were obtained mostly from the frequency domain method, although time domain analysis gives the results that are more coherent.

“…This excavated soft clay has high water content and is not suitable as a construction material; therefore it is normally transported for landfill. In recent years, there has been an environmental push worldwide to continually seek new reuse applications for various waste materials (Puppala et al, 2011;Arulrajah et al, 2012Arulrajah et al, , 2014Rahman et al, 2014). This excavated soft clay can be used as a sustainable construction material, when its engineering properties are improved.…”
