Bitumen Grade AH130 — Penetration-Grade Asphalt Binder for Standard Paving

Bitumen Grade AH130 is a penetration-grade asphalt binder derived from crude oil, with a penetration value of 120–140 (0.1mm) at 25°C. It falls under the Chinese penetration-grade classification system and is used as a base binder in road construction and paving.

AH130 bitumen has a penetration range of 120–140 (in 0.1mm units) measured at 25°C under 100g load for 5 seconds, tested per ASTM D5. This makes it one of the softer grades in the AH bitumen series.

 AH130 is commonly used for general road paving, hot mix asphalt production, asphalt mixtures, and surface treatments, particularly in projects requiring a softer, more workable binder.

AH130 bitumen performs best in moderate to cooler climate conditions, where its softer penetration grade provides good flexibility without excessive softening under heat.

 AH130 is best suited for low to moderate traffic roads. Heavy traffic or high-load applications typically require harder penetration grades (such as AH70 or AH90) or polymer-modified bitumen for greater rutting resistance.

 AH130 has the highest penetration value (120–140) among the standard AH grades, making it the softest and most flexible. Lower-numbered grades like AH50 and AH70 are harder and stiffer, suited for hotter climates and heavier traffic.

Yes, AH130 is commonly used in hot mix asphalt applications as a base binder, offering good adhesion and workability during mixing and compaction.
