  • Abstract:
  • In order to reduce the dangerous pollutants released into the atmosphere during the creation of conventional Hot Mix Asphalt (HMA), Warm Mix Asphalt (WMA) technology, a sustainable way of pavement construction, has been developed. It is essential to design a long-lasting pavement surface while safeguarding society and the environment. The current study compares the rutting characteristics of WMA with Cashew Nut Shell Liquid (CNSL), a green warm mix additive, with the prevalent WMA technology with sasobit, and with the traditional hot mix asphalt, taking into account the potential benefits of organic additives of WMA technology. In this study, CNSL and sasobit, were added to VG-30 bitumen at their optimum dosages of 2% and 3% of the bitumen’s weight to produce warm mix asphalt with CNSL (WMA-CNSL) and warm mix asphalt with sasobit (WMA-Sasobit), respectively. WMA-CNSL exhibited a reduction of 17.01 % and 42.4 % in rut depth compared to that of WMA-Sasobit and HMA respectively and offered excellent resistance to permanent deformation due to the adhesive properties of CNSL. The experimental investigations are justified by the statistical analysis. The results of an ANOVA analysis for the rut depth showed that the type of mix had a significant impact on the resistance of bituminous mix to rutting.
