USE OF THE K-MOULD IN DETERMINATION AND ANALYSIS OF THE ELASTIC AND SHEAR PROPERTIES OF ROAD MATERIALS FOR FLEXIBLE PAVEMENTS

This paper describes a laboratory test system for the rapid determination of the elastic and shear properties of road building materials, including asphalt. The system includes a dynamic loading and data acquisition system, commonly referred to as the "K-mould". The computer-controlled loading and data acquisition systems are described briefly. Typical material parameters such as stress dependent elastic modulus and Poisson's ratio, cohesion and friction angle are determined from a single test specimen. Some typical results and their application are discussed in this paper. The paper also discusses methods that were used to validate the laboratory-derived results. This was done by evaluating deflection basins measured by Multi-Depth Deflectometer (MDD) and also by comparing with Falling Weight Deflectometer (FWD) results.
