The possibility of modification BND 60/90 bitumen produced at JSC Ukrtatnafta (Kremenchuk, Ukraine) with maleic anhydride has been considered. effect amount, process time and temperature on the operating characteristics modified studied.

The effectiveness of natural Gilsonite on the performance properties modified bitumens was studied. Three samples having different ratios that are 6%, 8% and 10% by weight base bitumen which PG 64-16 grade were prepared. physical storage stabilities four investigated means conventional tests. short-term long-term aging processes conducted with rolling thin oven pressure vessel tests, respective...

The aim of this research is to evaluate the rheological properties industrial waste modified bitumen. varying proportion polypropylene ranging from 0% 20% weight bitumen at 5% interval with 60/70 penetration grade was used. asphalt binder modification prepared by using high-speed mixer temperature 150 °C 190 °C. conventional test like softening point, penetration, ductility, flash and fire poin...

the neat bitumen, an oil refining by-product, has its own inherent weakness under long-time loading at low and high temperatures. these performance limitations of neat bitumen have led researchers to modify its physical andmechanical properties. according to several studies, polymers can be used to modify the properties of bitumen. due to much lower production costs and aiming to reduce environ...

Atomic force microscopy (AFM) is capable to picture the topology of bitumen at a submicrometer level and optical spectroscopy can gather chemical information [1-3]. Here we combine AFM and Raman spectroscopy, which allows a better specification of the chemical origin of bitumen. AFM imaging was performed from the topology, following with Raman imaging from the same area correlating the chemical...
