Résumé
[EN] In the construction of highways and roads, one of the main activities is earthworks. This activity has an economic and
environmental impact that cannot be overlooked. The classic method, based on the use of mass diagram models and optimization,
does not take into account the type and quality of the material found on site, making it difficult to optimize the actual flow
of each material. The ICOM method (Intelligent Method of Optimized Mass Compensation) allows the optimization of classic
works such as excavations and fillings resulting in the optimization of operating costs. This versatile method contemplates
different options for each project and allows choosing the most appropriate one taking into account, among other factors, the
distance travelled by each type of material, which translates into the amount of CO2 emitted and waste generated. This is
why the use of the iCom method will enable us to make the work sustainable, while reducing environmental pollution and the
amount of waste. This article compares the results obtained by applying the ICOM method with those that can be obtained
with the classic method for twenty-four work projects in Spain and Portugal. The results analysed show that the ICOM method
achieves a significant reduction in financial costs between 5% and 14.1% and a shortening of the time needed to carry out the
work. The method also obtains a reduction in CO2 emissions (between 5.1% and 14%), while generating a smaller volume of
waste materials, which implies a reduction in environmental impact. Furthermore, this method provides the reports, plans and
diagrams necessary for the complete definition of the earthworks to be carried out
