The aim of this work is the characterization of road Portland cement concrete formulated with brick waste provided by brickyards. The present work focuses first on an experimental study in which different mixes made with brick waste have been developed using recent LCPC method. Then, the mechanical performances of these mixes were determined through several laboratory tests. Finally, a modelling of the mechanical characteristics was carried out using several models of the literature in order to evaluate the relevance of these models for the case of brick waste concrete. During this investigation, a decrease in mechanical characteristics was observed with the increase of the percentage of substitution of brick waste, but this decrease remains moderated up to a percentage of 30%. Finally, the models of de Larrard et al., which are used to predict the different mechanical characteristics of normal aggregates concrete, are proved to be all relevant for also brick waste concrete.
