The test results show that the continuous composite slab with lower level of prestressing can meet the requirement of ultimate state under normal serviceability and has better ductility.
The first frequency method of estimating the fatigue serviceability on small and medium span railway concrete bridge is discussed in this paper through three piece test beam under fatigue load.
