Description:

This report describes the results of an experimental and analytical effort to define the vehicle induced load environment in an at-grade, concrete tie/ballast transit track structure. The experiment was performed on the UMTA transit track oval at the Transportation Test Center in Pueblo, Colorado in order to establish an initial data baseline which could be extended to include data from tests conducted on various transit track structural systems. Standard experimental techniques generally were used to measure the pressures, strains, and applied wheel/rail loads in the various track structure components; however, innovations were effectively introduced for measuring pressures on the bottom of the concrete tie and in the ballast. Track design methods and analytical computer techniques for predicting the load environment in the various track components were evaluated through comparisons with the experimental data. Design conservatism in the tie/ballast transit track systems was evaluated from the aspect of stress criteria versus other design factors based on experience and initial capital costs versus maintenance costs for transit systems.
