Description
Demolished concretes are being recycled to produce recycled concrete aggregates (RCA) in different scales around the world. Therefore, applications of RCA as a construction material are being popular by replacing conventional materials. Many research studies have confirmed the potential use of RCA to be applied as an unbound pavement material. However, presence of constituents such as reclaimed asphalt pavement (RAP) in RCA effects on its native properties. Therefore, this study evaluates performance characteristics of RCA with RAP under dynamic loading condition. A series of “repeated load tri-axial (RLT)” test was conducted on RAP blended RCA samples to evaluate the elastic and plastic deformation characteristics with increase of load cycles. The elastic deformation was characterised by resilient modulus and slightly dropped with increase of RAP from 0, 5, 10 to 15% in RCA. Further, it observed a trend of small increase of the plastic deformation of the RCA with the increase of RAP portion. However, presence of RAP up to about 15% in RCA did not significantly affect on the accumulation of permanent strain.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
