Abstract: The measurement of track stiffness, or track modulus, is an important parameter for assessing the condition of a railway track. This paper describes a method by which the dynamic track modulus can be determined from the ...

Abstract: The legal limitations on the amount of biodegradable municipal solid waste (MSW) disposed of to landfill have led to the development of a range of pretreatment processes known generically as mechanical biological treatment ...

Abstract: This paper presents the results from a series of centrifuge tests and three-dimensional finite-element (FE) analyses, which examined the benefits of combining a footing with a monopile as a solution for foundations that ...

Abstract: This paper presents data on gas and leachate flow rates and leachate levels obtained during a

Abstract: Scientific design of a railway track formation requires an understanding of the subgrade behavior and the factors affecting it. These include the effective resilient stiffness during train passage, which is likely to depend ...

Abstract: This paper describes model tests used to investigate how ballast shoulder width and height contribute to a railway sleeper’s resistance to lateral movement for a range of shoulder widths and heights. Deflection and resistance ...

Abstract: The sleeper/ballast interface is an essential stage in the transfer of train loads from a railway track structure into the ground. Generally, only a small number of ballast grains support the sleeper base. The resulting ...

Abstract: A two-phase liquid/gas flow numerical model has been used to investigate the presence of elevated pore water pressures in a 20-m-deep municipal solid wastes (MSW) landfill underlain by a fully drained leachate collection ...

Abstract: Electrostatic charge sensing technology has been used to monitor adhesive wear in oil lubricated contacts. Previous work in this area demonstrated that “precursor” charge events may be detected ...
