Blending of Recycle Concrete Aggregates for use in Base Course Construction

This paper presents an examination of the self-cementing phenomenon of the road construction material known as recycled concrete aggregate .The aggregates resulting from the recycling of the products of demolition lie within the scope of local materials replacement and this study contributes to their valorization in the field of civil engineering, particularly in roads. This study aims to develop the best economic solution by blending of recycled concrete aggregates for use in base coarse construction. Therefore, the objective of this project is to investigate the properties of blended Recycled Concrete Aggregate including optimum moisture content, maximum dry density, and bearing strength. In this study, six different types of RCA samples were subjected classification tests such as particle size distribution, plasticity, compaction test and California Bearing Ratio (CBR). Results were compared with those of the MORTH and found that “RA01-100/RA02-0� and “RA01-80/RA02-20� samples are sitting in the margin of the minimum required specifications of base materials while others are lower than that.
