Abstract: Jute reinforcement has been tried with demolition waste in embankments and sub base construction. Optimum position of jute geotextile has been found 1/3 H from surface. By using jute geotextile, shear strength parameters such as cohesion(C) developed marginally and angle of internal friction (φ ) increased from 31.50° to 38°. With increase in natural aggregate (NA) in blended mixture, maximum dry density (MDD) increases, mainly because of lower particle density and higher water absorption of recycled aggregates (RAs) compared to NAs. CBR values of a mix of RA and NA (60: 40) has been found over 30%, which is minimum CBR value for roads of high traffic volume.
