Material Performance of Anti-Differential Disturbance Concrete Based on the Vehicle–Bridge Coupling Vibration Theory

For the purpose of splicing widening bridges without interrupting traffic in expressway reconstruction and extension projects, different types anti-differential disturbance concrete (ADC) were developed. This paper experimentally investigated mechanical performance ADC under influence traffic–vehicle coupling vibration. The experimental device, with one end fixed other vertically vibrated, was designed to simulate vehicle–bridge vibration on an existing old bridge. Different degrees simulated by adopting specimens made standard molds integral plate molds. compressive strength performances normal-type (NADC) high-performance (HPADC) tested. Owing differential disturbance, NADC increased 10~20%, that HPADC almost unaffected. flexural tensile strengths decreased some extent. can both meet requirement bridge splicing, is superior NADC.
