Asphalt Cement Grade (AC) - Infinity Galaxy

Here are six asphalt cement (AC) viscosity grades: AC-2.5 (which is the softest grade), AC-5, AC-20, AC-30, AC-40 (which is the hardest grade). As a brief explanation, AC-2.5 is asphalt cement with a target viscosity of 250 poises at 60c. (250 are divided by 100). As mentioned above, for other grades, the divided number for each grade stands ...

Viscosity Grade Of Bitumen - Orinoco Oil Corporation, S.A

Therefore, although asphalt binders are of the same AC grade they may behave differently after construction. Temperature susceptibility (the change in asphalt binder rheology with temperature) can be somewhat determined because viscosity is measured at three different temperatures (penetration only is measured at 25°C (77°F)).

The potential use of tar sand bitumen as paving asphalt ...

The bitumen used for this study was the oil produced during an in situ steamflood project at the Northwest Asphalt Ridge (Utah) tar sand deposit. Two distillation residues were produced, one at +316/sup 0/C and one at +399/sup 0/C. However, only the lower boiling residue met ASTM specifications, in this case as an AC-30 asphalt.

Construction Division Materials and Pavements Section

Binder Specification. Asphalt Cement (AC) Most AC binders are used in hot applied surface treatments, but other uses include precoating, tack coat, and recycling. The AC nomenclature uses numbers to indicate the stiffness or viscosity of the asphalt. As the number gets higher, the binder gets stiffer/harder.
