CRUSHED BRICK BLENDS WITH CRUSHED CONCRETE FOR PAVEMENT SUB-BASE AND DRAINAGE APPLICATIONS

Demolition materials are generated by demolition ac tivities and account for a major proportion of the waste materials present in landfills. Crushed brick and crushed con crete are major components of demolition materials. Recycled crushed concrete, crushed brick and crushed rock ar e however viable substitute materials for natural r esources used as construction materials in engineering applications. This paper presents the laboratory testing results of various proportions of crushed brick blends with crushed co ncrete. The engineering properties obtained were co mpared with existing local authority specifications for pavemen t subbase and drainage systems to ascertain the pot ential use of crushed brick blends in these applications. The dem olition materials for the experimental works were c ollected from a recycling site in Victoria, Australia.
