A novel concept of polymer railway sleeper is proposed in this study that has the potential to meet static performance requirements within cost hardwood timber. The existing challenges composite sleepers, such as low or high cost, can be overcome using innovative concept. Such a proclamation proven through limit state design criteria and series experimentations. Results show polyurethane foam a...

This paper reports the full-scale experimental measurements of temperature distribution over surfaces bridges' steel-concrete beams under influence positive and negative ambient temperatures. It has been established that is distributed unevenly along vertical direction a bridge's beam. was found metal beam accepted higher values. The maximum registered difference between reinforced concrete sla...
