Abstract
Sposób modyfikacji asfaltu mieszanina dicyklopentadienu, styrenu, kauczuku polibutadienowego i siarki charakteryzuje sie tym, ze mieszanine zawierajaca 1.37% dicyklopentadienu, 75,74% styrenu, 18,43% kauczuku polibutadienowego i 2,57% siarki wygrzewa sie przez okres 5 godzin w temperaturze 40°C, po czym dozuje sie porcjami intensywnie mieszajac do asfaltu 50/70 rozgrzanego do temperatury 140°C w ilosci 3% mieszaniny w stosunku do asfaltu 50/70. Nastepnie mieszanine wygrzewa sie przez 20 godzin w temperaturze 140°C.The asphalt modification method, a mixture of dicyclopentadiene, styrene, polybutadiene rubber and sulfur, is characterized by the fact that the mixture containing 1.37% dicyclopentadiene, 75.74% styrene, 18.43% polybutadiene rubber and 2.57% sulfur is heated for 5 hours at 40 ° C, after which it is dosed in portions, intensively mixing into asphalt 50/70 heated to 140 ° C in an amount of 3% of the mixture in relation to asphalt 50/70. The mixture is then heated for 20 hours at 140 ° C.
