The member states of the European Union have decided to reduce by 30% the greenhouse gases emissions by 2020. Reaching this goal will require taking the necessary measures, and our process makes for a big step towards that end. The LEA® process can reduce by 50% CO2 emissions.

It has been proven in 2008 by the LCPC (independent laboratory associated to the French road administration) through a comparative study led during the construction of the RD231 road in Seine et Marne (Paris area).


The public representatives in charge of road construction issues are favorable to the LEA process. According to them (see Asphalt Handbook p 766), the Lea Process is considered as one of the most performing processes of its category.
