Exploration of the load fatigue test method for cement concrete wheels

The bending and pulling fatigue test is critical for inspecting cement concrete. The existing fatigue test equipment is expensive and non-conducive for the grassroots sector of construction units. The purpose of this study is to explore a scheme to modify an asphalt mixture rutting test machine to p...
