Abstract Incorporating several recycled materials can make an asphalt mixture sustainable, eco-friendly, and economical. In this investigation, annealed glass and PET with 2.36–1.18 mm were incorporated into the hot mix asphalt (HMA) using a dry process at proportions of 2.5 %, 5 %, 7.5 %, and 10 % of the 4.63 % optimum bitumen, following the Marshall Mix design. The effects of annealed glass and PET on the Marshall properties of HMA were compared, and those of modified HMA were also contrasted with those of the control samples. After analyzing the findings, the inclusion of glass particles in the asphalt mixture enhanced the density and Marshall Stability, whereas PET provided negative results. PET provided the HMA with stiffer properties than glass particles, as indicated by the MQ value analysis. These modifiers considerably impact the variability of Marshall Properties, except for the MQ value. HMA with more glass inclusions performed better flow and stability than the control sample, but PET had the opposite outcomes. PET and glass were significant for the Marshall properties following ANOVA.
