VISCOSITY BITUMEN

Asphalt cement grade of bitumen is one of the main categories of viscosity grade bitumen. With AC grading, asphalt binder is specified by properties it possesses before it undergoes HMA making process. Asphalt binder samples Viscosity of standard bitumen measured at 60 ºC (the maximum pavement temperature). Good to know that the measurement unit of the viscosity grading system is Poise (cm-g-s = dyne-second/cm2). The viscosity grading is done on both original (as-supplied) asphalt binder called AC grading and aged residue binder called AR grading. The AC grading is related to absolute viscosity at 60 c in 100 poises. Here are six asphalt cement (AC) viscosity grades: AC-2.5 (the softest grade), AC-5 (viscosity is 500 ± 100 poise at 60° C (140° F)), AC-10, AC-20, AC-30, and AC-40 (the hardest grade (viscosity is 4000 ± 800 poise at 60° C (140° F))). As a brief explanation, AC-2.5 is asphalt cement with a target viscosity of 250 poises at 60c. (250 are divided by 100).

ABM-Petro’s Viscosity grade Bitumen AR-1000 exported by ABM-Petro is strictly in compliance with (ASTM D3381-09) and AASHTO M226-80 (2008) standards. There are two series of viscosity grade bitumen from the American Association of State Highway Officials. There is a number indicating the viscosity in hundreds of poises at 60 °C. After the bitumen has been aged, the second series is denoted AR (aged residue) followed by a number indicating the viscosity in poises (not hundreds of poises) at 60°C. It is more accurate to specify binder consistency and to determine the temperature susceptibility of the bitumen by measuring viscosity. Viscosity is a measure of fluidity. Viscosity defines the fluid property of the bituminous material. The general term for consistency is viscosity, which indicates resistance to flow. The hot climate generally suits high viscosity grades from AR-1000 to AR-16000. The AR viscosity of bitumen is graded through the RTFOT system, in which the viscosity of bitumen (asphalt) is measured at 60 °C (140 °F) after the roll on thin film oven test. The viscosity-grade bitumen AR-2000 exported by ABM-Petro complies with ASTM D3381-09 and AASHTO M226-80 (2008) requirements. The American Association of State Highway Officials (AASHTO) offers two grades of viscosity-grade bitumen. One is denoted AC, followed by a number indicating the viscosity in hundreds of poises at 60 °C. After the bitumen has been aged, the second series is denoted AR (aged residue) followed by a number indicating the viscosity in poises (not hundreds of poises) at 60°C. The measurement of viscosity provides a more accurate method of specifying binder consistency and an effective method of determining the temperature susceptibility of the bitumen. Viscosity is the opposite of flow. Viscosity defines the fluid property of the bituminous material. The general term for consistency is viscosity, which indicates resistance to flow. The hot climate generally suits high viscosity grades from AR-1000 to AR-16000. The AR viscosity of bitumen is graded through the RTFOT system, in which the viscosity of bitumen (asphalt) is measured at 60 °C (140 °F) after the roll on thin film oven test.

A more precise method of specifying binder consistency and a more efficient method of determining the temperature sensitivity of the bitumen can be obtained by measuring viscosity. Viscosity is the opposite of flow. The viscosity of the bitumen determines its fluidity. Viscosity is a measure of resistance to flow, and it is the general term for consistency.
