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.

重载循环荷载作用下粒状基质的性能。该项目旨在根据改进的岩土工程设计延长道路和轨道的寿命。在过去十年中，对安全耐用的道路和铁路的需求稳步增加，以适应更快和更重的交通。本项目将从地质力学的角度研究压实颗粒废物（洗煤和粉煤灰）在循环荷载下的性能，特别是与重载工业相关的性能。它将使用岩土实验室测试和现场监测来开发一个计算模型，将不同载荷频率下的相关强度和变形特性结合起来。预期成果是可持续的、更具复原力的交通基础设施。
