Load Stress Analysis on BFRC-RCC Composite Pavement

Abstract:

Article Preview

The finite element model for the basalt fiber reinforced concrete(BFRC)-roller compacted concrete(RCC) composite pavement structure is formed, by the model the influence of the BFRC and RCC panel thickness, elasticity modulus and foundation Equivalent Resilient Modulus on the complex road load stress can be summarized as: with the increasing of the composite pavement slab thickness, the stress at the end of the below plate shows decreasing trend, but the above end of the plate stress increased with the increasing of relative thickness of laminates; the increasing of concrete elastic modulus will make the stress in the end of this laminate increase, while the end of the adjacent laminates stress will reduce; with the increasing of the equivalent modulus of elasticity of roadbed top, the stress of laminates decreases. The results of the analysis are available as the reference to optimize the design of BFRC-RCC composite pavement.
