Asachi”, Iasi,, 700050, Romania 3 ) Romanian Professional Association for Road and Bridges- Moldavian Branch, Iasi, Romania 4 )Romanian Centre for Road Engineering Studies and Informatics-CESTRIN, Bucharest, Romania The papers presented in the frame of this new annual edition of the international symposium on Highway and Bridge Engineering are focusing on some of the most challenging issues of the actual road research, such as sustainable development of roads and of road transport, development of long lasting pavements and validation of the new concepts by using accelerated testing facilities, assessment of functional quality of pavements and road transport management, traffic investigations, new road materials, construction and testing technologies and modern solutions for earth and slope consolidation. 1. SUSTAINABLE DEVELOPMENT OF ROADS AND OF ROAD TRANSPORT Sustainability is defined, according Brundtland definition [1], as “development that meets the needs of the present without compromising the ability of the future generations to meet their own needs”. As usually, in the particular case of roads, sustainability is defined by taking into consideration the economic, social, and ecological aspects, in the decision-making and evaluation process. Road infrastructure can be divided into two main categories: technical and social. The papers presented in our symposium are addressing the first category, the main emphasis being on sustainable aspects of physical road pavement structures. In their paper, entitled Pavement Recycling: an Environmentally Sustainable Rehabilitation Alternative, Joel Oliveira, Hugo Silva and Paulo Pereira, from the Department of Civil Engineering, University of Minho, Guimarães, Portugal, focus on preservation of environment, by reducing the use of material and natural resources together with important economic savings. In this context, their analysis of a heavily trafficked urban road rehabilitation project, has finally led to the conclusion that pavement recycling should be considered as a prime solution for pavement maintenance/rehabilitation. This solution allowed the maintenance of the
