ABSTRACT: This study presents a discussion of three prominent mixture models and assesses their predictive capabilities for several fly ash-modified soil mixtures. This study specifically focuses on the ability of the mixture models to predict moisture-density characteristics of compacted fill containing varying percentages of fly ash. The results of this study show that the behaviour of the mixture is a function of the fly ash component and the fractions of each component contained in the total mixture. This particular focus is in response to greater emphasis being placed on incorporating sustainability into geotechnical engineering. Specifically, it is hoped that the results of this study will be used to facilitate greater utilization of fly ash in earthwork construction.

RESUMEN: Este estudio presenta una discusión sobre tres importantes modelos de mezclas y se establecen sus capacidades predictivas para varias mezclas de suelo modificado con cenizas de carbón. Específicamente, este estudio se centra en la capacidad de los modelos de mezclas para predecir características de humedad-densidad de rellenos compactados con diferentes porcentajes de cenizas. Los resultados de este estudio muestran que el comportamiento de las mezclas es una función del contenido de cenizas y de la fracción de cada componente en el total de la mezcla. Este enfoque es una respuesta del gran énfasis puesto en incorporar la sostenibilidad en la ingeniería geotécnica. Específicamente, se espera que los resultados de este estudio sean usados para facilitar un mayor uso de las cenizas en construcción de obras geotécnicas.
