Use of recycled concrete aggregate for pavement

Jan 01, 2020 Concrete constitutes 40% of the total C&D waste as shown in Fig. 10.2 ( Oikonomou, 2005 ). RCA can be used as 100% replacement of natural aggregates in base course and subbase ( CCAA, 2013 ). RCA is, therefore, the most commonly used recycled material in pavement constructions. Table 10.1.
