Abstract

The construction industry has always been one of the most resource-intensive industries. However,with the depletion of natural resources, it is imperative that the industry finds innovative ways to reduce theusage of virgin materials and utilize recycled materials. One such material that has gained significant attentionin recent years is Reclaimed Asphalt Pavement (RAP). RAP is the recycled material obtained from the removalof old asphalt pavements. It is a sustainable material that can be used in various construction applications,including concrete bricks. This report explores the utilization of RAP in concrete bricks. The objective ofthis study is to investigate the effect of incorporating RAP on the properties of concrete bricks. The studyinvolves preparing concrete brick specimens with varying percentages of RAP and conducting compressivestrength, water absorption, and freeze-thaw resistance tests. The results indicate that RAP can be effectivelyused in the production of concrete bricks, with up to 40% replacement of virgin aggregates. This report presents a comprehensive overview of the use of RAP in concrete bricks, including the advantages and disadvantages, technical properties, and mix design considerations. The findings of this study will be useful for the construction industry in promoting sustainable practices and reducing the environmental impact of construction activities.
