Improvement of Road Pavement Sustainability. Case Study Application

Road infrastructure has an important role in the transportation system by connecting communities, ensuring a crucial contribution to economic development and important social benefits. They have vital importance in sustainable cities and bring the most important economic and social benefits to all public assets. This paper describes the design process of pavement improvement of old Albanian roads by using geogrid or geotextile material and presents the data information gathered findings, and conclusions that can be drawn. The case of study is the rehabilitation design of Fier-Seman old road. The American Association of State Highway and Transportation AASHTO standards methods have been used to design pavement system rehabilitation depending upon the existing condition and improving the bearing capacity performance. This method includes consideration of the following items: pavement performance, traffic volume and composition, roadbed soil, properties of materials for construction, drainage, environment, reliability, and life-cycle costs.
