This paper discusses the drained static triaxial testing on granite ballast material with different amount of breakdown fouling and water content. Large-scale, 10 in., triaxial equipment was used for this testing program at the University of Massachu

The allowable speed limit of railroad tracks is dependent upon maintaining track conditions that will ensure the safety and ride quality. Settlement of railway tracks amplifies the dynamic loads of trains, which results in high maintenance costs and

Repeated loading of railroad track results in deformation of the track foundation materials. The degree of ballast fouling and the amount of moisture affect the rate and magnitude of both elastic and plastic deformation of the track. As train traffic

Railway ballast is an important component of the track substructure that provides vertical, lateral, and longitudinal support, increases track resiliency, reduces stress applied to the subgrade, and facilitates the drainage of water away from the tra

Railway ballast under repeated traffic loading deforms and deteriorates. Increases in the rate of settlement in ballast decreases its useful life and contributes to geometry roughness and poor ride quality. Based on laboratory and field studies, as w

The performance of ballasted railway systems is commonly compromised by the infiltration of fine material into the voids of the ballast. This sand and finer grained materials in the ballast is known as fouling. Increased fouling can cause decreases i

Railroad ballast as a layer of track substructure performs important tasks such as increasing the bearing capacity of the sleepers, providing large voids for drainage and resisting the forces applied to the super-structure. Contamination of ballast a

Excessively fouled ballast can result a high amount of plastic settlement and reduction of vertical and lateral resistance of the track. A significant portion of railroad maintenance costs is associated with degraded fouled ballast. Therefore, it is
