The goal of this study is to provide a mixture design that needs a minimum amount of cement content for pavement concrete. The reduction in cement content was achieved by using different aggregate gradations. Maturity curves were developed for the final design mixtures as inputs for computer models that describe the long term performance of the materials. This work was funded by a grant from the FHWA for the Highways for Life Program. The mixture developed has been used on FM 1938 near Ft. Worth, TX with satisfactory performance. Changing the proportions of the same materials under the same ambient conditions led to a different maturity-strength relation. The predicting of concrete strength in terms of maturity logarithm equation was close from the actual strength. Optimization the aggregate gradation should combined by selecting the appropriate type and dosage of water reducer with a suitable water-cement ratio that provides the desired workability and strength.
