Pavement cover plates are railway ancillary facilities, which are designed to cover the cable trenches. In recent years, Ultra High Performance Fiber Reinforced Concrete (UHPFRC) has been encouraged to be applied for pavement cover plates production by the Railways Ministry of the People’s Republic of China.
In this study, a cost-effective UHPFRC material, named as Eco-UHPFRC, was designed firstly in the laboratory. The workability, mechanical properties and durability of this material were tested and all of them achieved the required value. Then, the manufacture procedure of the plates was determined in the factory after several production trials. Before application, the appearance, size and load-carrying capacity of the produced plates have to be examined according to the requirements of quality control. By virtue of its excellent performance, Eco-UHPFRC designed in this study has been successfully employed to produce pavement cover plates which are widely used in the high-speed railway projects in China.
