Bitumen AH-70 is a high-quality paving grade bitumen widely used in road construction, asphalt mixtures, and waterproofing applications. This grade belongs to the asphalt hard grade (AH) classification, produced through vacuum distillation of crude oil, followed by air blowing processes to achieve the required consistency. Bitumen AH-70 offers excellent binding strength, durability, and resistance to deformation, making it suitable for heavy traffic roads and high-temperature regions.
Typical properties of Bitumen AH-70 include:
| Specification | Value |
|---|---|
| Penetration at 25°C (0.1 mm) | 60 – 80 |
| Softening Point (R&B) | 46 – 56 °C |
| Viscosity at 60°C | ≥ 3000 Poise |
| Viscosity at 135°C | ≥ 400 cSt |
| Ductility at 25°C | Minimum 100 cm |
| Flash Point (COC) | ≥ 230 °C |
| Loss on Heating (163°C, 5h) | ≤ 0.5 % |
| Solubility in Trichloroethylene | ≥ 99 % |
These parameters ensure that Bitumen AH-70 performs reliably in asphalt paving, road surfacing, and industrial applications.
• Excellent adhesion between bitumen and aggregates.
• High resistance to rutting and cracking under heavy traffic.
• Durability against oxidation and weathering.
• Workability for both hot-mix asphalt and waterproofing materials.
• Stable performance under varying climatic conditions.
• Highway and expressway construction with heavy traffic loads.
• Urban road paving and resurfacing projects.
• Airport runways and taxiways requiring stability and resilience.
• Industrial waterproofing membranes and protective coatings.
• Roofing and insulation materials.
Bitumen AH-70 is supplied in various forms depending on client requirements:
• New steel drums (180–200 kg net)
• Jumbo bags (1 MT)
• Bulk bitumen in tankers or vessels for large-scale projects
• Store in cool, dry, and covered areas to prevent contamination.
• Avoid heating above 175–180°C to maintain product stability.
• Use protective clothing, gloves, and goggles during handling.
• Follow international standards for storage and transport.
