AR 4000
AR 4000 is an aged-residue grade: it is classified by viscosity at 60°C after rolling thin-film oven ageing (3,000–5,000 poise), which reflects how the binder behaves once it is in the pavement. It balances stiffness and flexibility, which is why it is one of the most widely specified grades for hot-mix asphalt in warm and temperate climates.
Where AR 4000 is used
Viscosity grade bitumen is classified by its viscosity at 60°C — the maximum pavement temperature — which predicts rutting performance more reliably than penetration alone.
- 01Hot-mix asphalt wearing and binder courses
- 02National and urban road construction and resurfacing
- 03Road maintenance and overlay programmes
- 04Industrial and commercial paving
Conforms to AASHTO M226 (Table 3)
Supplied to AASHTO M226 Table 3. Grading is performed on the RTFOT residue; flash point is tested on the original binder.

Storing AR 4000
Temperature: Keep paving grades between roughly 140°C and 170°C in working tanks, and store at the lower end for long holds. Avoid repeated heat-up and cool-down cycles.
Tanks: Use insulated, heated steel tanks with a closed vent system. Dedicate a tank to one grade, or clean it fully between grades to avoid cross-contamination.
Safety: Water and hot bitumen must never meet, because it causes violent foaming. Use heat-resistant PPE, and keep a dry, ventilated area with no ignition sources near the vents.
Shelf life: Bitumen hardens slowly under prolonged heat. Rotate stock, avoid holding it at peak temperature, and re-test before use after long storage.
