The use of construction and demolition waste (CDW) in construction constitutes a significant step towards a more sustainable society and also creates a new market opportunity to be exploited. In recent years, several cases studies have emerged in which CDW were used in geotechnical applications, such as filling materials and in unbound pavement layers. In this paper, the behavior of CDW, natural granular material (PMT) and the mixture of 50% CDW and 50% PMT investigated experimentally. The resilient modulus test device was used for this study. The main purpose of this work is to determine the influence of geogrid reinforcement on resilient modulus and permanent deformation. Cylindrical specimens with 15 cm diameter and 30 cm length were prepared with a vibratory proctor device for resilient modulus test. For this reason, a single layer geogrid was placed at depths of 7.5 cm of the test specimen. As a result of this study, it is seen that the use of geogrid in the CDW, PMT and mixture of 50% CDW and 50% PMT may be used for road base construction reduces the permanent deformation value. The maximum resilient modulus was observed in PMT specimen.
