Development of a Mechanistic Model for the Determination of Track Modulus

Crawford, Shane, Murray, Martin H., & Powell, John (2001) Development of a Mechanistic Model for the Determination of Track Modulus. In 7th International Heavy Haul Conference, 10-14 June 2001, Brisbane, Australia.


The current world-wide trend towards increased axle loads and faster trains has resulted in increased damage to heavy haul routes. A simple, accurate method is required for determining track modulus, to improve track design and prediction of degradation. The paper describes the on-going development of a mechanistic model for track modulus. It also describes a series of field tests, with the following outcomes: comparison of several methods for determining track modulus based on track deflection under load; achieving a better understanding of track behaviour under load; and calibration of the mechanistic model against test results.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
