The vision of our project is to reduce global warming, and the mission of the project is to construct flexible pavement without affecting the environment. The agent zeolite was mixed with asphalt mix to reduce carbon dioxide level and increase the strength of the pavement. Hydrophobic silica sand was used in the asphalt mix for the replacement of filler content to reduce porosity. The secondary aim of our project is to reduce the crack in pavement by using steel mesh. The reason behind the steel mesh is to increase the life span of the flexible pavement. Cost expenses of pavement construction and maintenance were compared with our innovative pavement construction as per the CPWD (Central Public Work Department). The aggregate tests such as impact test, abrasion test, crushing test were conducted as per IS- specifications. California bearing ratio and dry density test by core cutter method were identified the soil stability, type of soil which was under the pavement to increase strength. Pavement thickness was calculated for WMM (Wet Mix Macadam) and BC (Bituminous Concrete) by CBR test as per IRC 37-2001. Marshall Stability test, which deals with the stability and flows property of asphalt mix to obtained highly stabilized pavement layers. The IRC (Indian Road Congress) codes of practices were used for the pavement design standards and codes of Indian standards for the test procedures of bitumen.
