Performance of granular matrix under heavy haul cyclic loading. This project aims to enhance the longevity of roads and tracks based on improved geotechnical design. The demand for safe and durable roads and railways to accommodate faster and heavier traffic has increased steadily in the past decade. This project will research the performance of compacted granular waste (coalwash & flyash) under cyclic loads, particularly relevant to heavy haul industry, from a geomechanics perspective. It will use geotechnical laboratory testing and field monitoring to develop a computational model, incorporating the relevant strength and deformation properties at varied load frequencies. The anticipated outcome is sustainable, more resilient transport infrastructure.

在重拖循环载荷下颗粒基质的性能。该项目旨在根据改进的岩土设计，以提高道路和轨道的寿命。在过去的十年中，对安全，耐用的道路和铁路的需求稳步增加。该项目将从地质力学的角度研究紧凑的颗粒废物（煤炭和苍蝇）的性能，尤其是与重型行业有关的。它将使用岩土技术实验室测试和现场监测来开发计算模型，并在不同的负载频率下结合了相关的强度和变形属性。预期的结果是可持续的，更具弹性的运输基础设施。
