Abstract:
The results show that (a) the flexural fatigue life of normal concrete beams is higher than the fatigue life of layered beams utilizing dense concrete or latex modified concrete at lower stress levels but is lower than that of hybrid layered beams at higher stress levels and (b) essentially the same fatigue strength was obtained for beams containing only a 2-inch layer of either dense concrete or latex modified concrete at the surface as for beams containing these concretes full depth.
