Abstract:
Through the combination of theoretical and experimental particle packing methods, optimum aggregate blends can be obtained, which will lead to pavement mixtures with reduced cement content. This presentation presents a study of using pavement workability test to justify the effectiveness of cement reduction in pavement concrete mixtures. Based on the laboratory test results, an improved mixture design procedure aided by the particle packing degree, and the minimum excess paste-to-aggregates volume ratio is also presented.
