To　quantize　the　property　differences　between　construction　recycled　concrete　aggregates　(RCA)　and　pavement　RCA,　the　quantitative　analysis　with　Euclidian　distance　indicating　the　diversity　of　two　sequences　was　carried　on,　based　on　the　data　of　property　trials　that　include　apparent　density,　water　absorption,　crushing　index　value,　etc.　The　Euclidian　distance　of　single　properties　and　variance　of　entire　property　for　construction　RCA　were　all　greater　than　that　of　pavement　RCA.　Therefore,　pavement　RCA　comes　closer　to　the　natural　aggregates　than　construction　RCA.　Additionally,　the　entire　property　of　pavement　RCA　is　more　stable　than　construction　RCA.　As　a　result,　pavement　RCA　favors　the　application　in　project　of　higher　requirements.
