2019-8-5  The objective of this research study is to present a procedure for designing Cold In-Place Recycling (CIR) mixtures through balancing cracking and rutting for these mixtures. Eight CIR mixtures were prepared using two recycling agents (foamed and emulsified asphalts), then cured for three days at two temperatures (140oF and 50oF), and compacted at two gyration levels (30 and 70 gyrations).
