Performance of granular matrix under heavy haul cyclic loading

Grant


Scheme


  • Linkage Projects

Abstract


  • The demand for safe and durable roads and railways to accommodate faster and heavier traffic has been increasing steadily in the past decade. The proposed research will examine in a geomechanics perspective, the performance of compacted granular waste (i.e. coalwash & flyash) under cyclic loads, particularly relevant to heavy haul industry. Supported by geotechnical laboratory testing and field monitoring, a computational model will be developed, incorporating the relevant strength and deformation properties at varied load frequencies. The project aims to deliver tangible strategies for optimising both the short and long term stability of this matrix, thereby enhancing the longevity of roads and tracks based on improved geotechnical design.The project outcomes will enhance our understanding of the mechanics of compacted granular waste materials under repeated loads for roads and railways. The knowledge gained will provide a sound platform for sustainable development of transport infrastructure and enhance Australia┬┐s commercial advantage in designing resilient transport systems.
