Computer simulations of SBS modified bitumen and carbon nanotube/SBS were carried out to have research on the mechanism capacitating effect nanotubes SBS-modified bitumen. Through molecular dynamics simulation, binding energy (Ebinding), radial distribution function (g(r)) mixing (Emixing) composites analyzed according Velocity-Verlet algorithm, enhancement compatibility was quantified influenc...
due to performance grade )pg) zonation of different parts in iran and poor properties of 60/70 penetration grade bitumens for pavement applications, suitable polymer modifed bitumen was produced. to fulfll this purpose, different pmbs samples were produced using 60/70 penetration grade bitumen and various percentages of vb (20 and 25%), with different percentages of sbs calpre...
In this work, we report about the mechanical relaxation characteristics of an intrinsically self-healable imidazole modified commercial rubber. This kind of self-healing rubber was prepared by melt mixing of 1-butyl imidazole with bromo-butyl rubber (bromine modified isoprene-isobutylene copolymer, BIIR). By this melt mixing process, the reactive allylic bromine of bromo-butyl rubber was conver...
The ageing of the bitumen during storage, mixing, transport and laying on the road, as well as in service life, are the most important problems presented by the use of bitumen in pavements. This paper investigates the possibility of using waste cooking oil (WCO), which is a waste material that pollutes landfills and rivers, as an alternative natural rejuvenating agent for aged bitumen to a cond...
