Use of inert C&D materials for seawall foundation: A field-scale pilot test

Abstract

The generation rate of construction and demolition (C&D) materials in Hong Kong has well exceeded the demand rate. An innovative solution has been developed by the Hong Kong Special Administrative Region Government to use the inert portion of C&D materials, denoted as public fill, for seawall foundation construction. A field-scale pilot test has been conducted to evaluate the constructability and engineering performance of the foundation so as to establish the viability of the solution. Details of the pilot test and results of the performance evaluation are presented in this paper. More importantly, the viability of an innovation solution to achieve effective allocation of sand fill resources, and conservation and recycling of inert C&D materials has been established. © 2006 Elsevier B.V.
