摘要

In Flanders, up to 20% of the coarse natural aggregates in concrete mixtures for certain Received 18 June 2019 applications in road pavement construction may be replaced by high-grade recycled Received in revised form 23 August 2019 concrete aggregates (RCA). The RCA and resulting recycled aggregate concrete (RAC) have to Accepted 23 August 2019 comply with the high-grade criteria specified in the Flemish ‘Standard Tender Specifications 250 version 3.1’ and require extensive and time-consuming testing.
