Abstract:This study introduces an innovative bionanocomposite to enhance the sustainability of asphalt pavements. The bionanocomposite is made from montmorillonite clay and castor oil. Preswelling of montmorillonite clay in an isopropanol/water mixture facilitated intercalation of castor oil into the clay interlayer space and the subsequent replacement of castor oil with asphalt molecules. The displaced oil molecules plasticized the asphalt matrix, thereby improving the asphalt's workability and resistance to low-tempe… Show more
