| Abstract |
A warm-mix asphalt (WMA) produced at 100 degrees C and incorporating waste plastic film flakes was evaluated. The investigation comprised two stages analysing the WMA and a conventional HMA with the same plastic material. The first stage established the WMA composition. The second stage comprised performance evaluation, for which the incorporation of plastic slightly increased stiffness, and fatigue resistance was similar for both mixtures. WMA with plastic was the worst in the uniaxial compression test and the best in the wheel-tracking test. The conclusion is that WMA incorporating waste plastic is a promising solution for low to intermediate traffic volume road infrastructures. (c) 2021 Elsevier Ltd. All rights reserved. |
