Abstract: Acoustical warning devices are designed to warn trespassers of an approaching train. This study evaluated the urgency and detectibility of potential warning sounds.
Determining Bond-Slip Characteristics of Prestressing Tendons with Varying Geometries in Two Concrete Mixtures
Keywords: Track, ties, concrete, bond-slip, prestressing tendons
Abstract: Untensioned pullout tests were conducted to obtain the bond-slip characteristics of two groups of prestressing tendons used in concrete railroad tie production. The purpose of...
Keywords: Concrete crossties, water damage, center cracks, cyclic loading
Abstract: To investigate the impact of moisture on crack growth and other tie damage, UIUC researchers subjected pretensioned concrete crossties and small-scale beams to repeated loading...
