Abstract

Glass fiber reinforced polymer (GFRP) composite bars are considered durable alternative to regular steel bars for reinforcing concrete members, in corrosive environments. In concrete pavements, dowel bars are used to transfer loads between adjacent panels across construction, control, and expansion joints. Such load transfer occurs through shear action in the dowel bar. Steel dowel bars tend to corrode prematurely. GFRP bars have high corrosion resistance, however, the transverse shear properties of GFRP bar vary widely, depending on their chemical and physical properties. This paper presents comprehensive review of literature along with experimental investigation of GFRP bars for use as dowel bars in concrete pavement, at the construction and control joints. Two series of GFRP bars having diameters of 16mm and 32 mm were investigated and reported.
