摘      要：Recycled Aggregate(RA)has only been used as sub-grade applications,roadwork and unbound materials because it is believed that RA has lower strength and poorer quality than normal *** paper assesses RA quality by propos-ing a new testing *** new procedure is developed by using correlation information among the standard twenty three tests commonly employed in the construction *** of RA from ten demolition sites were ob-tained with service life ranging from ten to forty *** additional set of samples was specifically collected from the Tuen Mun Area 38 Recycling Plant,Hong Kong for *** characteristics of these eleven sets of samples were then compared with normal aggregate samples.A Vandermonde matrix for interpolation polynomials coefficient estimation is employed to yield detailed mathematical relationships between results of two particular tests,from that redundant tests can be *** orders of interpolation polynomials are used for comparison,hence the best-fit equations with lowestfitting errors from different orders of polynomials can be *** paper shows that four out of twenty three tests are required in the new testing procedure.
