Abstract

This paper identifies the need for quantitative durability testing of rock for use on dynamically stable rock armoured slopes. The derivation and use of a suite of engineering tests for rock quality is considered, and the limitations of Simple accept/reject criteria discussed. Recent developments in techniques for the quantification of armour slope profiles and armour unit shapes are presented. The use of a roller mill test to predict rock abrasion performance is discussed. The paper describes the use of advanced techniques to predict rock armour performance, allowing for long term reductions in armour unit size and roundness. The paper seeks to provide a framework within which to study the inter-relationships between wave climate, armour design, rock wear resistance, and weight loss and rounding in service.
