ABSTRACT
This article presents a first approach to the mechanical and physical performance for a granular material mixed with crushed recycled hydraulic concrete, the blend was made with the aim to assess its viability to be used in pavement’s granular layer construction. Four mixtures were prepared with different recycled concrete contents including granular material without addition. The blended granular materials were characterized based on the Colombian Highways Specifications. According to the experimental results was possible to observe an improvement in the mechanical behavior in terms of California bearing ratio (CBR) and resilient modulus on the blended aggregates.
