The rejuvenation of epoxy modified bituminous binders is a topic much debate because such may not be able to melt at high temperatures and restore their properties using recycling agents. This paper presents the results an experimental program developed evaluate re-usability bitumen, or by three agents: aromatic-based agent, aliphatic-based soft binder. impact these agents on response aged was ...
Aggregates constitute major part of the pavement structure. The engineering properties of the aggregates, as well as its shape (i.e. form and angularity) and texture, substantially affect the overall performance of the pavement (Kuo and Freeman 1998, Maerz 2004). A number of researchers reported that form and surface texture of aggregates have significant effect on the mechanical property of th...
After closure of a waste disposal cell in a repository for radioactive waste, resaturation is likely to cause the release of soluble species contained in cement and bituminous matrices, such as ionic species (nitrates, sulfates, calcium and alkaline ions, etc.), organic matter (mainly organic acids), or gases (from steel containers and reinforced concrete structures as well as from radiolysis w...
Based on literature data, the paper analyzed impact of transport operational indicators related to quality road surface coverage safety. It presented results experimental studies effect adhesion cationic thermostable additive properties bitumen and asphalt concrete. The authors identified that introduction this leads an increase in viscosity softening temperature bitumen, its mineral materials,...
The characteristics of initial crudes Yablunivske field (Poltava, Ukraine) and the properties blended have been examined to select ways their further processing. crude oils were found be heavy high-sulfuric without light distillates. possibility obtaining paving bitumen from under study has considered. Distilled obtained through distillation this blend was meet requirements for commercial 100/1...
