Research of the Properties of Basalt Fiber Reinforced Polymer Bar for Continuously Reinforced Concrete Pavement

Article Preview

Abstract:

Continuously reinforced concrete pavement (CRCP) does not require any contraction joints which is a high-performance pavement structure type that just need a sufficient number of reinforced pavement longitudinal configuration to constrain sideway random crack width. With continuous basalt fiber as reinforced material and synthetic resin as the matrix material and adding appropriate adjuvants, basalt fiber reinforced polymer (BFRP) bar form a new type of material after pultrusion processing and surface treatment technologies. BFRP on the mechanical properties were studied by two kinds of test methods which are using extensometer strain detection and fiber optic strain sensing and the parameter of homegrown BFRP bars mechanical properties. Because of the lower tensile elastic modulus of BFRP bars compared with rebar, the mechanical properties of basalt fiber-steel wire composite bar has been studied along with the research corrosion and flexural properties of BFRP bar.
