Abstract
Przedmiotem zgłoszenia jest asfalt modyfikowany, który charakteryzuje się tym, że zawiera od 75% mas. do 97% mas. asfaltu oraz od 3% mas. do 25% mas. modyfikatora asfaltu w postaci przetworzonej metodą wytłaczania kompozycji poliuretanowo-gumowej zawierającej piankę poliuretanową i rozdrobnione odpady gumowe w postaci granulatu gumowego. Zgłoszenie obejmuje też sposób otrzymywania modyfikowanego asfaltu, który przeprowadza się w trzech etapach. W pierwszym etapie piankę poliuretanową mieli się na granulat, a następnie otrzymany granulat miesza się z rozdrobnionymi odpadami gumowymi do postaci granulatu, przy czym ilość granulatu pianki poliuretanowej w mieszaninie wynosi od 25% mas. do 50% mas., natomiast rozdrobnionych odpadów gumowych w mieszaninie od 50% mas. do 75% mas. W drugim etapie otrzymaną kompozycję poliuretanowo-gumową zawierającą granulat pianki poliuretanowej i granulat gumowy poddaje się przetworzeniu w procesie wytłaczania znanym sposobem przy użyciu wytłaczarki, przy czym wytłaczanie prowadzi się w temperaturze w zakresie od 140°C do 250°C, a otrzymaną w tym procesie wytłoczynę przetworzonej kompozycji poliuretanowo-gumowej, w postaci drobnego proszku, chłodzi się uzyskując gotowy modyfikator asfaltu. W trzecim etapie uzyskany modyfikator asfaltu miesza się z asfaltem naftowym w temperaturze w zakresie od 160°C do 250°C.The subject of the notification is modified asphalt, which is characterized in that it contains from 75% by mass. up to 97% by mass asphalt and from 3% by mass up to 25% by mass asphalt modifier in the form of an extruded polyurethane-rubber composition containing polyurethane foam and crushed rubber waste in the form of granulated rubber. The application also includes a method for obtaining modified asphalt which is carried out in three stages. In the first stage, the polyurethane foam was ground into granulate, and then the obtained granulate is mixed with comminuted rubber waste to form a granulate, with the amount of polyurethane foam granulate in the mixture being from 25% by mass. up to 50% by mass, while shredded rubber waste in a mixture from 50% by mass up to 75% by mass In the second stage, the obtained polyurethane-rubber composition containing the polyurethane foam granulate and the rubber granulate is processed in an extrusion process by a known method using an extruder, the extrusion being carried out at a temperature in the range from 140 ° C to 250 ° C, and obtained in this process the extrudate of the processed polyurethane-rubber composition, in the form of a fine powder, is cooled to obtain a ready asphalt modifier. In the third stage, the obtained asphalt modifier is mixed with petroleum asphalt at a temperature in the range from 160 ° C to 250 ° C.
