| Abstract: |
Micro-tunneling and pile driving are two example applications in which the surface roughness of construction materials may be significantly altered during installation. Quantification of this change in surface roughness as a result of large displacement shear-induced wear is a necessary precursor to achieving optimum interface design. This paper describes the results of an initial experimental study that investigated the change in surface roughness of curved interfaces as a result of shear-induced wear. Even for limited shear displacements, results show quantifiable changes in surface roughness and interface strength and demonstrate the importance of considering the shear-induced wear of construction materials. |
