Title: Steel Belted...Steel Fibers Reinforce Houston's Beltway 8
Author(s): J. H. toper and C. P. Henry
Publication: Special Publication
Appears on pages(s): 95-114
Keywords: aspect ratio; bond performance; fatigue endurance limit; reflective cracking; residual strength factor (R10,50 ); steel fibers; thin concrete bonded overlay (TCBO)
Abstract:This narrative discusses design and construction aspects related to a steel fiber reinforced concrete bonded overlay repair project on the existing Houston Beltway 8 Freeway. Several previous steel fiber reinforced paving projects are reviewed. An experimental program involving steel fibers complete in 1983 (1-610 Overlay Project in Houston) is comprehensively reviewed with special attention paid to reflective cracking reduction. Design considerations such as mix design, modulus of rupture, residual strength factors, overlay bond performance, and evaporation rate are discussed. Fatigue endurance limit laboratory test data are presented and a correlation to design applications using residual strength factors is suggested.
