Abstract

Przedmiotem zgłoszenia jest sposób modyfikacji lepiszczy asfaltowych z zastosowaniem kopolimeru, który polega na tym, że dwuskładnikowy kompozyt chitozan-kwas 2-akryloamido-2-metylopropanosulfonowy zawierający od 7,13% do 38,08% mas. chitozanu i od 61,98% do 92,87% mas. kwasu 2-akryloamido-2-metylopropanosulfonowego w ilości od 0,5% do 6,5% w stosunku do masy lepiszcza asfaltowego, dodaje się do upłynnionego lepiszcza asfaltowego i miesza się w temperaturze od 150°C do 180°C przez czas od 45 do 120 min, mieszadłem ścinającym do uzyskania homogenicznej mieszaniny, po czym zmodyfikowane lepiszcze asfaltowe kondycjonuje się w temperaturze do 150°C do 160°C przez czas od 30 do 90 minut.The subject of the application is a method of modifying asphalt binders using a copolymer, which consists in that a two-component chitosan-2-acrylamido-2-methylpropanesulfonic acid composite containing from 7.13% to 38.08% by weight of chitosan and from 61.98% to 92.87% by weight of 2-acrylamido-2-methylpropanesulfonic acid in an amount of from 0.5% to 6.5% by weight of the asphalt binder is added to the liquefied asphalt binder and mixed at a temperature of from 150°C to 180°C for a time of from 45 to 120 minutes with a shear mixer until a homogeneous mixture is obtained, after which the modified asphalt binder is conditioned at a temperature of up to 150°C to 160°C for a time of from 30 to 90 minutes.
