Use of recycled concrete aggregate for pavement ...

01/01/2020  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. Recycling of waste concrete in pavement construction not only decreases materials going into landfill, but also ...
