Przedstawiono wyniki badań wybranych właściwości reologicznych lepiszczy asfaltowych poddanych symulowanemu starzeniu z zastosowaniem różnych procedur laboratoryjnych. Badaniom poddano próbki asfaltu drogowego gatunku 50/70 zwykłego oraz modyfikowanego dodatkiem elastomeru SBS w ilości 3, 5 i 7% (m/m). Starzenie krótkoterminowe lepiszczy asfaltowych symulowano stosując trzy wybrane metody laboratoryjne:...
The paper deals with the problem of improving rheologicaJ properties of road bitumens by modification with elastomers. The aim of the paper is to extend the knowledge on rheology of polymer modified binders. An attempt is made to provide a mathematical description of the constitutive law appropriate to bituminous binders subjected to static loading. The object of our laboratory tensile tests were...
