Project Description


As a leading European construction company (with an annual revenue of €7,3 billion), BAM strives to achieve circular mobility by focusing its innovations on attaining lower CO2 emissions and more efficient use of energy and materials. 

Project description

In 1998, BAM started with the development of LEAB (Low Energy Asphalt Concrete) an innovative type of asphalt that uses less energy, less scarce natural resources, and has lower CO2 emissions than conventional asphalt. In order to investigate the potential of this new type of asphalt, BAM commissioned the Impact Institute* to assess the environmental costs of their product compared to conventional asphalt. Results indicated that placing LEAB instead of conventional STAB (Rubble Asphalt Concrete) creates a positive impact of  €257.000 on the environment per kilometer of highway. 

Benefits to the client

The project provided BAM insight into the size of environmental impacts occurring in the asphalt production chain and made those impacts comparable. The results help BAM to steer future innovations in the areas where they are most needed and prove that sustainable innovations, such as LEAB, can create value for society without causing extra financial costs.
