Abstract


In this works, we have modified a bitumen from Amposta by using the Friedel and Crafts reaction with toluylene-2,4-diisocyanate in presence of aluminium trichloride, presenting as well as the characteristics of the original bitumen as the ones of the modification products. We have made technological test, aging of thin film, rheological test, thermical susceptibility and components analyses.
