In general, the physical and rheological properties of asphalt binder are directly affecting resistance mix to permanent deformation (rutting), water damage, thermal cracking. The degradation in these leads severe distresses that appear pavement and, consequently, make repair maintenance very expensive. Since modified-asphalt cement may help minimize such aforementioned distresses, this researc...

Diels-Alder chemistry has been used for the thermoreversible cross-linking of furan-functionalized ethylene/propylene (EPM) and ethylene/vinyl acetate (EVM) rubbers. Both furan-functionalized elastomers were successfully cross-linked with bismaleimide to yield products with a similar cross-link density. NMR relaxometry and SAXS measurements both show that the apolar EPM-g-furan precursor contai...

A systematic study was performed to understand the effects of devulcanizing agent dibenzamido diphenyl disulfide (DBD) on vulcanization and devulcanization process a sulfur-cured ethylene-propylene-diene monomer (EPDM) rubber. The influence DBD investigated by mixing with virgin rubber curative system. waste achieved varying amounts ranging from 0.4 13.8 wt% temperatures 150 200°C. quality vulc...

The influences of nanosilica and modified on cure, compression set, mechanical swelling characteristics are studied in blends ethylene-propylene-diene monomer (EPDM)/styrene-butadiene rubber (SBR). In EPDM/SBR composites, the made from rice husk ash (RHA) was utilised as a reinforcing nanofiller. interaction between matrix at interface is crucial for production composites. This study uses bis[3...

The reliability of a transmission and distribution system can be significantly improved by employing a predictive maintenance program. For such a program to succeed, the condition of the total system must first be established. This has been accomplished by applying a totally passive diagnostic technique that analyzes radio frequency (RF) pulses emitted by a cable system while it is energized in...

Ethylene propylene diene monomer rubber is used as flexible thermal protection for rocket engines, well in blends with polychloroprene, which can be applied the aeronautical sector, and great potential defense sector. However, there not a considerable number of studies considering both polymers blend. In general, elastomer content quantification done by more complex instrumental methods. When p...

Bacteriol. 85:356-362. 1963.-An anaerobic organism which utilizes ethylene glycol as a source of energy and carbon has been isolated from mud. It is a long (5 mu), slender, motile, gram-positive, spore-forming rod, wi...
