Subject area: Quality/Test Procedures Several recovery procedures for asphalt emulsion residue have been used over the years, but there is no one procedure that has been universally accepted. In this study three recovery methods are used to obtain the residue of the emulsified asphalt: 1) distillation (ASTM D 6997), 2) evaporation (ASTM D 6934) and, 3) the newly approved moisture analyzer balan...

Bitumen is a commonly used material for road construction. According to environmental regulations, vegetable-based materials are applied for binder modification. Fluxed road bitumen containing a bio-flux oxidation product increases the consistency over time. The efficiency of crosslinking depends on the number of double bonds and their position in the aliphatic chain of fatty acid. The main goa...

Asphalt binder film thickness has relation to mixing temperature and content in hot mix asphalt, which influences mixture’s performance. A significant variation assessing the asphalt been observed literature. Development of state art technology Superpave specification requires study actual at micro-level. This estimates micro-level compares results with those obtained through analytical models ...

Asphalt functions as an aggregate binder in the road pavement mixture. The rapid construction of roads causes need for asphalt to increase, while its availability is limited. government promoting use natural (Asbuton) alternative oil asphalt. However, performance from Asbuton not good. Uneven content and hardness are factors causing it be less effective a binder. It necessary improve by modifyi...
