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.
