  • Performance characteristics of recycled concrete

    Use of recycled concrete aggregates (RCA) as a pavement material is one of the most sustainable engineering applications for the pavement industry. Investigation on the performance characteristics of RCA, such as elastic and stone deformations of RCA is therefore, needed to assess RCA's applicatio

  • Use of recycled concrete aggregate for pavement

    2020-1-1 · The use of recycled concrete aggregate (RCA) for the production of concrete is limited to low strength concrete due to the difficulty in quality control and poor strength. RCA is, therefore, primarily used in pavement base and subbase courses as a substitute to natural crushed rocks.

  • Reclaimed Concrete Material Used as Pavement

    2020-7-30 · RCM is most often used as aggregate in a base or subbase course. Although it is generally of high enough quality to be used as base material, RCM can also be used for lesser applications like embankment or fill material.. Since RCM is a crushed material, the angular aggregates will provide excellent stiffness and load transfer capability.
