| Several bitumen samples were collected. These included 60/70 and 85/100 penetration grade bitumen's from the different refineries in Iran (i.e. refineries in Tehran, Isfahan, Shiraz, Tabriz and Arak). The primary standard tests were performed and the samples that met the local specifications were selected. In another study in Netherlands both standard and SHRP tests were performed on similar bitumens. Both mentioned tests were reported separately in a Bitumen Test Data Chart. It was shown that these had very close physical characteristics. For the samples in Netherlands, having performed the SHRP tests, the corresponding performance grade classification was noted. F or the Iranian bitumen's, the standard test results were reported on the curves that were obtained in Netherlands (i.e. the curves showing correlation's between performance grade and penetration grade classification). From latter the relative SHRP performance grade class was obtained for Iranian bitumens. It was found that the 60/70 and 85/l00 . penetration grades corresponds to PG 64-22 and PG 58-22 class in SHRP classification , respectively. | ||
