Abstract

Przedmiotem zgłoszenia jest lepiszcze asfaltowe, będące mieszaniną asfaltu z woskiem syntetycznym Fischera-Tropscha F-T o obniżonym śladzie węglowym LC będącym polimerem metylenowym, który jest alkanem syntetyzowanym z gazu syntetycznego na bazie węglowodorów lub gazu ziemnego i amidopoliaminami oleju talowego, które charakteryzuje się tym, że stanowi mieszaninę 96,9-98,9% m/m asfaltu oraz wosku syntetycznego F-T o zmniejszonym śladzie węglowym LC w ilości 1-2,5% m/m, korzystnie 1,5-2,0% m/m oraz amidopoliaminami oleju talowego w ilości 0,2-0,6% m/m, korzystnie 0,2-0,4% m/m. Jako asfalt stosuje się asfalt 50/70 zgodny z normą PN-EN 12591 według najnowszego datowania.The subject of the application is an asphalt binder, being a mixture of asphalt with a Fischer-Tropsch F-T synthetic wax with a reduced LC carbon footprint, being a methylene polymer, which is an alkane synthesized from a synthetic gas based on hydrocarbons or natural gas, and tall oil amidopolyamines, which is characterized in that it is a mixture of 96.9-98.9% m/m of asphalt and a F-T synthetic wax with a reduced LC carbon footprint in the amount of 1-2.5% m/m, preferably 1.5-2.0% m/m, and tall oil amidopolyamines in the amount of 0.2-0.6% m/m, preferably 0.2-0.4% m/m. The asphalt used is 50/70 asphalt compliant with the PN-EN 12591 standard according to the latest dating.
