Matrix of the testing program.
| | Natural aggregate/RCA | RAP | Minimum number of resilient modulus tests | Minimum number of CBR tests | Minimum number of repeated load triaxial tests |
| | Natural aggregate A, F, W | — | 3 | 3 | 2 | | RCA | — | 1 | 1 | — | | Blends of natural aggregates with RAPs | 4 × 3 | 3 × 3 × 4 = 36 | 3 × 3 × 4 = 36 | 7 | | Blends of RCA with RAPs | 4 × 3 | 3 × 4 = 12 | 3 × 4 = 12 | — | | Total | 52 | 52 | 9 |

Blended samples were prepared by mixing 25%, 50%, and 75% (by weight) of each RAP type with the natural aggregates and RCA. |
