In the economic and financial conditions of our time the cost of infrastructure works is often the main factor upon which decide to whether or not to make an investment in the South – Eastern Europe. Another important factor to be taken into account in the development of infrastructure investments is the environmental impact of construction. Thus, since the design phase is focused on using new technologies, performing to ensure two objectives: low cost and low environmental impact. This paper aims to draw up possibilities to reduce costs by using new technologies both to the foundation layers and layers of asphalt mixtures. The focus is on the use of new materials and technologies that have a positive environmental impact by reducing both transportation and production costs. Since the design phase, based on laboratory studies, it is proposed the use of hydraulic binders for execution of road foundation layers, the use of asphalt mixtures with high stiffness modulus and warm mix technology.
