Abstract

TDA has been successfully used in different civil engineering projects as a fill material in its pure state or mixed with soils in TDA-soil mixtures. Despite the superior geotechnical properties and successful applications of TDA, the size limitations between the available conventional laboratory testing equipment and the TDA particle sizes commonly used in practice are forcing the researchers and practitioners to conduct their tests on smaller TDA particle sizes rather than the actual sizes used in civil engineering applications. Moreover, several studies are conducted on TDA without due attention to the different sample sizes and their effect on the obtained results. So, the main focus of this research is to investigate the particle and sample size effects on the shear strength parameters of TDA using two commonly used test apparatuses, namely the direct shear and the triaxial.
