Resumen de A case study of recycling of reinforced concrete sleepers in Bulgaria
The dismantled and scrapped reinforced concrete railway sleepers are among thelargest flows of construction and demolition waste (CDW) in Bulgaria - it is estimatedthat their number has reached 3 million. Although some good reuse practices canbe identified, the prevailing majority of sleepers remain as not declared CDW. Untilrecently, the sleepers recycling was considered unprofitable. This study presents aninnovative approach to recycling reinforced concrete sleepers and technical performanceof recycled crushed stone. It has been established that this crushed stone canbe used for various construction purposes, including as coarse concrete aggregate,thus providing sustainable solutions which contribute to both environmental protectionand circular economy.
