To Perform Penetration Test on BitumenPenetration test is used to measure the consistency of bitumen, so that they can be classified into standard grad Greater value of penetration indicates softer consistency Generally higher penetration bitumen is preferred for use in cold climate and smaller penetration bitumen is used in hot climate areas.Standard Test Method for Softening Point of Bitumen (RingThis test method covers the determination of the softening point of bitumen in the range from 30 to 157°C (86 to 315°F) using the ring and ball apparatus immersed in distilled water (30 to 80°C), USP glycerin (above 80 to 157°C), or ethylene glycol (30 to 110°C) The values stated in SI units are to be regarded as the standard.PERFORMANCE GRADED BITUMEN SPECIFICATIONSPERFORMANCE GRADED BITUMEN SPECIFICATIONS Christina Chin Sustainable Infrastructure Management Department ARRB Group 500 Burwood Highway, Vermont South, Australia [email protected] ABSTRACT Penetration graded specifications for bituminous binders focus on the low service temperature (25°C) properties of the binder.ASTM D36/D36M 12ASTM D36/D36M 12 Standard Test Method for Softening Point of Bitumen (Ring and Ball Apparatus) 11 This test method covers the determination of the softening point of bitumen in the range from 30 to 157 ° C [86 to 315 ° F] using the ring and ball apparatus immersed in distilled water [30 to 80 ° C] or USP glycerin (above 80 to 157 ° C) 12 The values stated in either SI units or inch.Standard Test Method for Softening Point of BitumenStandard Test Method for Softening Point of Bitumen (Ring and Ball Apparatus)1 This standard is issued under the ﬁxed designation D 36; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision A number in parentheses indicates the year of last reapproval.Automatic ring and ball apparatus, Bitumen testingThis advanced microprocessor controlled automatic tester is used to determine the softening point of bitumen using water or glycerol as heating flu The softening point is taken by two suitably positioned light barriers and the temperature is measured by a PT100 sensor placed in a central position.Softening Point TestFeb 04, 2015· ASTM D36 95 AASHTOT53 06 Standard test method for softening point bitumen (Ring and Ball Apparatus) فحص نقطة الميوعة للاسفلت.

Bitumen Pen Grades

Bitumen is classified by the depth to which a standard needle will penetrate under specified test conditions This “pen” test classification is used to indicate the hardness of bitumen, lower penetration values indicating a harder bitumen, higher values eg 160/220 indicate a softer grade.

Standard test method (ASTM D36) for Softening point ofOct 28, 2017· 1 This method is useful in determining the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply 2 melting point is the temperature at which the bituminous binders have an equal viscosity (ie the consistency of all the grades will be same at the softening point eg if two samples have softening points of 30 °C and 80 °C respectively.Softening Point Test ASTM D36 [Urdu/Hindi] #MaawaWorldDec 23, 2017· Softening Point of Bitumen (Ring and Ball Apparatus) ASTM D36 The softening point is the temperature at which a material softens beyond some arbitrary softness This test method covers the.Softening point test on BitumenNov 30, 2018· AIM To determine the softening point of asphaltic bitumen and fluxed native asphalt, road tar, coal tar pitch and blown type bitumen as per IS 1205 1978 APPARATUS i) Ring and ball apparatus ii) Thermometer Low Range 2 to 80ºC, Graduation 02ºC Continue reading "Softening point test on Bitumen".
