“…According to [ 11 ], the elastic recovery of bitumens modified with a moderate amount of copolymer should not be lower than 50%. In the case of bitumens modified with high amounts of copolymer, this value should not be smaller than 70%.…”

“…One of the most popular copolymers used for modification of bituminous binders is thermoplastic elastomer styrene–butadiene–styrene (SBS) [ 9 ] developed in the 1960s [ 10 ]. The process of modification consists of three phases [ 11 ]: dispersion of polymer in a colloid mill, swelling of ultra-fine dispersion of polymer particles and maturing and, in the case of radial copolymer, cross linking, which takes place during cooling of the final product. In the swelling process the elastomer expands its volume several (up to nine) times [ 12 ], absorbing mainly the light fraction of bitumen [ 3 , 9 , 13 , 14 ].…”

“…Na lepiszcze oprócz tlenu atmosferycznego oddziałują również promienie UV, substancje zawarte w wodzie opadowej oraz środki stosowane do odladzania nawierzchni w okresie zimowym. Intensywność tego procesu zależy od rodzaju lepiszcza, zawartości wolnych przestrzeni w warstwie nawierzchni oraz zawartości asfaltu w MMA [2]. Na podstawie studiów literatury [3,5,6] można wyróżnić czynniki mające największy wpływ na szybkość starzenia krótkoterminowego.…”

“…In addition to the physical and mechanical properties, chemical properties are also important in the technology of bituminous mixtures -in particular the content of silica, which is the criterion for the chemical classification of igneous rocks. High acidity reduces the ability of asphalt to adhere to the aggregate, i.e., it weakens the adhesion, the main force on which the durability of bituminous composites is based (Błażejowski and Styk 2004). In this view, the łażan granodiorite, with the SiO 2 content not exceeding 65% (by weight) (majerowicz 1972) can be still classified as an unreactive rock, which makes it more suitable for bituminous mixtures than the granites from the Strzegom-Sobótka massif containing at least 70% of SiO 2 (majerowicz 1972).…”
