Use of High Percentage of Recycled Concrete Aggregate in Aircraft Stand Rigid Pavement

Abstract:

This paper describes a study that was carried to investigate the use of recycled concrete aggregate (RCA) in aircraft stand rigid pavement at the Singapore Changi Airport. The study aimed to recycle the concrete waste generated from the demolition of the existing aircraft stand rigid pavement to reconstruct the aircraft stand rigid pavement. The study was a continuation of a previous work in which 20% of RCA was used in the rigid pavement. In this study, laboratory tests were carried out to evaluate the use of up to 100% of RCA in rigid pavement. The test properties that were evaluated include compressive strength, flexural strength, drying shrinkage and resistance to chloride ingress. The study showed that it is viable to incorporate high RCA content in concrete.
