The  EXTROVERT  ROADS  2.0  project  proposes  joint  creation,  pilot  implementation  and  validation  of  an innovative IT tool namely, the XT-ROADS tool,  aiming to quantitatively assess and monitor the environmental impact  of  road  construction  and  maintenance  during  its  whole  life  cycle,  focusing  on  mitigation  and adaptation to climate change, the possibility of reducing the consumption of natural resources and achieving a reduction in construction costs. 
In this light, the environmental aspect of road construction will be assessed using the Life Cycle Assessment (LCA) method, which will determine the environmental impacts during the whole life cycle of the project, from cradle to grave.  
More specifically, the following phases of road construction, will be tackled: 
•  climate endurance validation 
•  earthwork,  
•  grading,  
•  paving,  
•  installation of drainage systems -   flood control works 
•  signage,  
•  lighting,  
•  technical structures (bridges, tunnels), 
•  routine maintenance and repairs,  
•  removal of road infrastructure,  
•  disposal or recycling of materials, and  
•  environmental rehabilitation of the site  
Moreover,  the  embodied  energy  of  all  raw  materials  and  necessary  equipment  for  the  construction, maintenance and end-of-life of the road, will be also dealt with. In this context, the extraction, processing, and manufacturing of construction materials such as aggregates, asphalt, concrete, and steel will be assessed. 
The transportation of materials and equipment is also included, considering factors such as distance traveled, fuel consumption, and emissions. 
The  proposed  XT-ROADS  tool  will  be  validated  in  all  above-mentioned  road  infrastructure  upgrading interventions in all partnering regions. Considering the engineering divergences in the EU road network in different  infrastructures  and  environments,  the  tool  will  provide  the  ground  for  direct  comparison  of environmental  performance  for  different  technologies  and  solutions  used  in  road  projects.  The  data integration involves international bibliographic Impact Assessment Methods, such as ReCiPe 2016 and CML 2001, providing a holistic view of the environmental impact. This analysis yields a comprehensive depiction of  the  environmental  footprint,  offering  distinctive  criteria  for comparing  alternative  solutions  based on different practices, construction materials, and technologies. 
Τhe  XT-ROADS tool will hence be a unique tool for stakeholders to complete a real assessment for the environmental assessment of road activities, optimizing public funding. Moreover, the project results will provide the basis for future engineering work to incorporate more environmentally friendly techniques and materials, concentrating on:  
•  Reduction of energy consumption, including fossil fuels and natural resources 
•  Reduction of GHG emissions from road construction and maintenance 
•  Preservation of natural resources used for road construction 
•  climate change adaptation and mitigation 
Especially in public procurement processes the new tool will allow public authorities to move away from the ‘cheapest price’ model and select solutions that are cost-effective, based not only on price, but also on the tender’s environmental performance, aligning thus with the principles of Green Public Procurement. On the other hand, this will incentivize the road infrastructure industry to roll out further innovations in the market with a view to making road infrastructure construction and maintenance greener. 
The new tool contributes to the achievement of the output indicator RCO116 Jointly developed solutions, and result indicator RCR104 Solutions taken up or up-scaled by organizations as detailed below, despite the fact that it is not evaluated based on the PORIG of the program, within the framework of RSO3 .2.Developing and enhancing sustainable, climate resilient, intelligent and intermodal national, regional and local mobility, including improved access to TEN-T and cross-border mobility
