Abstract

Fast track concrete was developed for full-depth repair of jointed concrete slabs prior to bituminous overlay on New Jersey's Interstate 295. The New Jersey Department of Transportation requirements for the concrete included: a compressive strength of about 2500 psi and a modulus of rupture of about 350 psi in 6 to 7 hours after placement operations; use of locally available materials and normal aggregate gradations; use of accelerators limited to nonchloride-based admixtures; and workability for placement and finishing operations. Essential to the successful production of very high early-strength concrete include the mix proportions, concrete temperature, admixture dosage rates, curing, and early age thermal insulation of the pavement joint.
