Jun 01, 2013  The resilient modulus of HMA with RCA 0 °C is 2.1–4.9 times higher than that at 20 °C, while at 10 °C, the resilient modulus is 1.5–3.7 times higher. Therefore, the resilient modulus of HMA made with RCA exhibits much more dependence on in-service temperatures than conventional mixtures.
