• Abstract:
  In an attempt to increase the tensile strength of LMC and reduce cracking, steel fibers were added to a LMC mix. The results are what is termed as "latex-modified, fiber-reinforced concrete" (LMFRC). LMFRC was placed on Hayden Bridge as an experimental overlay. ; The LMFRC overlay has performed well and has not yet developed any visible cracks. The overlay has not delaminated or rutted. The skid resistance is comparable to a standard PCC deck. ; Recommendations for improved construction practices can be found in the Construction/Interim Report that was prepared in June 1993. Finally, because of it's improved performance, a LMFRC overlay may be considered as a permitted alternative to LMC.
