Bitumen AC30

Viscosity bitumen shows the efficiency and viscosity of bitumen and the mixing of bitumen with materials in the asphalt plant at different temperatures, rather than being indicative of the temperature conditions of the place where bitumen is used.
Bitumen AC 30 is a Viscosity Grade Bitumen which the Viscosity of the standard bitumen (asphalt) is measured at 60 degrees C (140 degrees F).
It is a Most AC binders are used in hot applied surface treatments, but other uses include pre-coating, tack coat, and recycling. The AC nomenclature uses numbers to indicate the stiffness or viscosity of the asphalt. As the number get higher, the binder gets stiffer/harder. Designations are added for polymer additives (SBR for styrene-butadiene-rubber, P for styrene-butadiene-styrene block copolymer, and TR for tire rubber). Application temperatures of asphalt cements, especially the more viscous grades, are from 300°F to 400°F.

Application of Bitumen Viscosity grade AC30

Viscosity grade bitumen asphalt can be applied on original asphalt which is AC (asphalt cement) grades or aged residue AR (aged residue) grades. The main common usage of this product is in road making at temperate regions.
AC grades indicated viscosity at 60 °C actually the number after AC showed 0.01 absolute viscosity in poises at 60 °C. For instance, AC-5 means the bituminous asphalt cement has viscosity of 500 poises at 60°C. The number after AR indicated viscosity in poises at 60 °C. Common viscosity grades asphalt cement are AC-2.5, AC-5, AC-10, AC-20, AC-30,AC-40. AC-10 is a designed bituminous asphalt which is mostly used in hot climate because the viscosity is high.

Bitumen AC30 Specification

Faragam guarantees that the Bitumen AC30 is produced in compliance and conformity to International of Standard ASTM D3381-09, AASHTO M226-80 (2008) and IS 73:2006, also meets the requirements of the following specification.

Applications

This kind of bitumen is suitable to be used for road construction projects in warm & dry regions. Also, it can be used for producing some kind of asphalt primer.
Also, Bitumen AC 30 is used in road construction, surfacing, and some industrial applications and manufacture asphalt mixes, bitumen emulsion, cut-back bitumen, and modified bitumen.
