Abstract: Rheology of bitumen is a constituent considered in bitumen physical properties to assess the deformation and flow of bitumen. Deformation and flow of the bitumen in hot mix asphalt (HMA) is important to determine the performance of HMA pavement. HMA pavement that deformed and flow too much may be susceptible to rutting and bleeding, while those that are too stiff may be susceptible to fatigue or thermal cracking. All this problem may happens during the service life of bitumen. The purpose of this research is to find the difference of reology that occur to bitumen in three main conditions which are fresh, after short term aging and after long term aging. This research involved two main laboratories experiment that are Rolling Thin Film Oven Test (RTFO) and Pressure Aging Vessel (PAV) besides three others tests, the Penetration Test, Softening Point Test and Viscosity Test. Four types of bitumen grade, 80/100, 60/70, PG76 and PG82 are compared. The result indicates that there is some changes in the rheological properties due to short and long term aging. Thus, the aging phases may affect the performance of HMA pavement.

Tq so much to Muhammad Husni becouse you are willing to gibe a comment dor my blog..Actually i'm quite busy right now and because of that i don't have enough time to put an information in my blog..I've a lot of info and memories that i want to share with people outside..Just give me a little bit time to do that..Anyway tq once again coz give a comment..I would like to know you better if i've got the chance..Maybe we can be a close friend..
