This study, from the Australian Rail Track Corporation (ARTC) Inland Rail project research, presents the resilient modulus from LWD for capping, structural fill, general fill and at foundation level, together with an example of near real-time reporting of the results...
Ballast is a major railway component whose behaviour is still not sufficiently controlled. The identification of mechanisms leading to track ageing is difficult to achieve as the process occurs over several years at particle scale. Models have been proposed to take...
Light drop-weight tester is a device for field tests and it is used for quick control of bearing capacity and compaction quality of built-in soils in different types of embankments. It is a modern device which is commonly used in Germany and now in Poland. The...
Plate loading tests (PLTs) have been used to evaluate the compaction quality of the railroad subgrade in Korea. Two methods to determine the design modulus are being used together; one is an unrepetitive plate loading test (uPLT) that obtains the subgrade reaction...
By means of a detailed parametric study of the settlement of ballast material per- formed on a full-scale track model, a predicting model for ballast settlement under cyclic loading has been developed. The model is based on track parameters: axle load, train speed and...
