• [Display omitted] •Chicken Feather (CF) Asphalt Concrete Mix (ACM) was designed and analyzed.•Un-processed CF yielded ACM with higher stability and density than processed CF.•Up to 0.3% unprocessed CF resulted in improved Marshall Stability, and stiffness.•Improved moisture and rutting resistance was observed at 0.15% CF content.•Decomposition tendency of the CF in the mix was also analyzed.•Microscopic and statistical analysis showed insignificant biodegradation. This paper discussed the results of laboratory experiments conducted on Chicken-Feather (CF) modified Hot-Mix-Asphalt (HMA) concretes. Marshall Mix design was employed to prepare the CF-HMA concretes. The effects of the CF on the mechanical, gravimetric, and volumetric properties of asphalt concrete were studied. Rutting performance, moisture resistance, and the ability of the asphalt concrete to protect the CF from decomposition have been analyzed. Results showed that the CF can improve the rutting resistance, increase the stability, and lower moisture sensitivity of the asphalt concrete. Extended moisture test results showed that the asphalt is capable of protecting the CF from biodegradation.
