A laboratory study of railway ballast behaviour under traffic loading and tamping maintenance
Aursudkij, Bhanitiz (2007) A laboratory study of railway ballast behaviour under traffic loading and tamping maintenance. PhD thesis, University of Nottingham.
Since it is difficult to conduct railway ballast testing in-situ, it is important to simulate the conditions experienced in the real track environment and study their influences on ballast in a controlled experimental manner. In this research, extensive laboratory tests were performed on three types of ballast, namely granites A and B and limestone. The grading of the tested ballast conforms to the grading specification in The Railway Specification RT/CE/S/006 Issue 3 (2000). The major laboratory tests in this research were used to simulate the traffic loading and tamping maintenance undertaken by the newly developed Railway Test Facility (RTF) and large-scale triaxial test facility.
