Extreme natural phenomena as the effects of climate change have become a threat by increasing their frequency and magnitude, globally, implicitly, in Europe and Romania. In order to prevent and to mitigate the impact, society must adopt fair and effective measures. Regarding the road transport system that is of a fundamental importance to the country's economy and its potential development, new transport infrastructure must be sustainable and immune to the effects of climate change. The sustainable road transport system includes pavements with a life cycle of more than 40 years, which are disaster resistant, without major degradation and loss of functionality and with a low environmental impact. The pavement sustainability assessment can be performed by using Life Cycle Assessment and Life Cycle Cost Analysis methods. In this paper, considering the results obtained with the Romanian PD 177- 2001 Normative, the Long Lasting and the Asphalt Institute, commonly worldwide used methods, the design of flexible pavements, based on sustainability criteria is considered and analyzed. Keywords: infrastructure; impact; traffic; elasticity modulus; asphalt. * Corresponding author: e-mail: dianadima3006@yahoo.com
