Abstract

Przedmiotem zgłoszenia jest sposób modyfikacji lepiszczy asfaltowych z zastosowaniem kopolimeru, który polega na tym, że dwuskładnikowy kompozyt chitozanowo-polianilinowy zawierający od 26,80% do 84,32% mas. chitozanu i od 15,68% do 73,19% mas. polianiliny 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. Następnie zmodyfikowany asfalt kondycjonuje się w temperaturze od 150°C do 160°C przez czas od 30 do 90 min.The subject of the application is a method of modifying asphalt binders using a copolymer, which consists in adding a two-component chitosan-polyaniline composite containing from 26.80% to 84.32% by weight of chitosan and from 15.68% to 73.19% by weight of polyaniline in an amount of from 0.5% to 6.5% by weight of the asphalt binder to a liquefied asphalt binder and mixing it 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. Then the modified asphalt is conditioned at a temperature of from 150°C to 160°C for a time of from 30 to 90 minutes.
