Cover Story: Recycled crushed concrete aggregate (RCCA) and reclaimed asphalt pavement (RAP) have been used as pavement base and subbase material for years. The physical and mechanical properties of these recycled materials have been revealed in various studies. Hence, microstructural properties are yet to understood. This article is a bridge between the microstructural and mechanical properties of RCCA and RAP. Cement-treated RCCA and RAP blends were observed using scanning electron microscope (SEM) for microstructural analysis. Micropores detected from image analysis were correlated with the compressive strength of the cement-treated base with different combinations of RAP and RCCA. Morphological and textural changes were also observed through SEM images.
