Abstract
This study has evaluated the mechanical performance of 100% Reclaimed Asphalt Pavement (RAP) stabilised under various curing periods. To this end, 540 different-age, cement-treated base (CTB) samples were made by using cement and Nicoflok mineral polymer (NMP) additive, and tested for unconfined compressive strength (UCS). Results of machine learning analyses revealed that the age, cement, NMP, water, and the compaction method, respectively, had the greatest effect on the UCS. Next, indirect tensile strength (ITS) tests were performed on 90 samples and then durability tests were done on some selected samples to find the volume change, weight loss, UCS and ITS. Then, triaxial resilient modulus (MR) tests were conducted on 2 large-diameter samples. According to the results, these samples had significant strength, durability and resilient modulus, and NMP-cement stabilised samples, compared with the cement-only case, not only increase the durability and strength, but also reduce the construction time of CTB layers.
