Abstract:

The approach for the proposed concrete tie research under the NEXTRANS Center funding was to characterize the abrasion demand on the concrete-tie rail seat, as well as the abrasion resistance of different rail seat materials and designs (e.g. concrete strength, porosity, admixtures, surface treatments, etc.) and tie pad materials (e.g. polyurethane, plastic, steel, etc.). The approach and methodology for this project included a thorough literature review, interviews with industry experts, concrete tie performance data collection, modeling, experimental testing, and ultimately the development of laboratory tests to objectively evaluate different rail seat materials based on their resistance to abrasion. The investigators are confident that the abrasion-related knowledge gained in thisproject willbenefit Tech Report modesof transportation that utilizeconcrete asa construction material,as well as the field of materials engineering.
