This report is concerned with the determination of relationship between asphaltic concrete surface course specifications and the level of performance of pavements constructed under these specifications. The relationship was investigated through comparative evaluation of deficient (in specification) and nondeficient sections using a combination of pavement condition rating and ride rating as the...

Palm oil clinker (POC) is a non-biodegradable palm mill by-product typically discarded in dumpsites. This study analyzed the performance of POC powder (POCF) as bitumen modifier terms conventional and engineering properties asphalt mixture. For study, base 60/70 penetration grade was utilized different POCF dosages (0, 2, 4, 6, 8% by weight bitumen) were added. The effectively modified with the...

The flexible pavement layers are very susceptible to damage due moisture or water. Excess on any of can cause before the designed lifetime. To improve quality layers, modifications asphalt mixtures required. This study aims compare performance asphaltic mixture that was constructed by using two different additives, which Wetbond-SP and Retona Blend natural aggregates. There were three tests con...

infection with hepatitis c virus (hcv) is a worldwide problem. among hcv proteins, core antigen (ag), besides its importance for diagnostic application is a prime candidate for component of a vaccine. herein, we report results of studies on production of the hydrophilic domain of core ag (2-122) in native conformation by an arabinose induction system in e.coli and the primary characterization o...
