Abstract

This thesis addresses municipal ash-modified and fly ash-modified concrete utilization for the transportation infrastructure. The mix design included unmodified (control) concrete (Mix A), fly ash-modified concrete (Mix B), and municipal ash-modified concrete (Mix C). The laboratory investigation was carried out through compressive, tensile, testing of the cylinders and flexural testing of concrete slabs on grade comprised of varying proportions of coal fly ash and MSW bottom ash. The load-strain relationships for experimental pavements was obtained through slab testing, modeled as a two-way infinite slab on an elastic foundation. A finite element model using STAAD-III was used to predict the stresses and deflection of the slab. For comparison, a simplified analysis was also performed to obtain stresses and deflections variations of the slabs, following ACI Committee 436. Based on the results presented in this report, conclusions were drawn to evaluate the ideal mix design for municipal ash-modified and fly ash-modified concrete.
