This paper presents the possibilities of reusing recycled materials in road pavement constructions. Waste materials came from old and damaged pavement layers. The reclaimed asphalt pavement (RAP) was used to create new layers of road surfaces - the base layers. The base layers were made of mineral-cement-emulsion mixtures (MCE). The main issue was to assess the impact of the RAP in MCE mixes on the physical, mechanical and rheological properties of the recycled base layer. The use of reclaimed asphalt in MCE mixes reduces road construction costs and allows for the ecological coexistence of the investment with the environment. The research results were developed as part of the project entitled "The innovative technology used the binding agent optimization that provides the long service life of the recycled base layer" (TECHMATSTRATEG1/349326/9/NCBR/2017) within the scientific undertaking of Strategic Research and Development Program entitled "Modern Materials Technology" (TECHMATSTRATEG I), which is financed by the National Center for Research and Development (Polish NCBiR).Keywords: MCE mixture; Road pavement recycling; Reclaimed asphalt pavement (RAP); Cement dusty by-products
