Abstract : The present study investigates in mechanical and elastic properties of concretes made with recycled asphalt pavement (RAP), without any pretreatment. For that purpose five families of concrete were designed with different substitution contents with a maximum of 50% RAP, at three water cement (W/C) ratios (0,50-0,60 and 0,70). During mixture procedure, the “two steps mixing approach” (TSMA) was applied. Controlled slump is 90-150 mm. Compressive tests and modulus of elasticity tests were conducted on hardened specimens at 28 days. Experimental results showed that the more RAP content increases in mix, the more mechanical and elastic characteristics decrease. It is the same when W/C ratio increases. Then, a good correlation between static modulus of elasticity and compressive strength is obtained. Finally, mathematical modeling using factorial design 2 2 is established in aim to quantify the effect of RAP and W/C ratio on response in terms of compressive strength and modulus of elasticity. Established models can predict both properties for hardened concrete, whatever the RAP content and whatever W/C ratio. Index terms - Environment, sustainable materials, concrete, recycled asphalt pavement concrete, recycling, valorization, compressive strength, static modulus of elasticity, factorial design, modeling.
