Asphalt & Bitumen Calculator (Metric, Pakistan)
Free online calculator for asphalt tonnage in Pakistan. Built around 2,322.7 kg/m³ standard hot mix asphalt density (≈ 145 lbs/ft³). Default units are metric — meters and centimeters — matching NHA (National Highway Authority) and provincial highway department specifications.
Asphalt in Pakistan — NHA Specifications
Pakistan road works generally follow the NHA (National Highway Authority) General Specifications. The most common bituminous mixes are:
- Asphaltic Concrete Wearing Course (Class A & B): 40–75 mm, dense-graded surface course.
- Asphaltic Base Course: 75–100 mm, coarse-graded structural layer.
- Bituminous Macadam: open-graded base course for stage construction.
- Surface Treatment / Seal Coat: low-cost surface protection.
Bitumen grade is typically 60/70 penetration for most regions, with 80/100 in northern areas for cold-weather flexibility.
Approximate Asphalt Price in Pakistan (2026)
| Material | Approx. Price (₨/tonne, delivered) |
|---|---|
| Asphaltic Concrete (wearing course) | ₨28,000 – ₨42,000 |
| Asphaltic Base Course | ₨25,000 – ₨38,000 |
| Bituminous Macadam | ₨22,000 – ₨34,000 |
| Bitumen 60/70 (binder only) | ₨180,000 – ₨240,000 / tonne |
Prices fluctuate with international crude oil, exchange rates, aggregate availability and transport distance from the plant. Use ₨34,000/tonne as a working midpoint for asphaltic concrete; always confirm with at least two suppliers.
Quick Tonnage Reference (Metric — Pakistan)
| Thickness | Coverage per Tonne | Tonnes per 100 m² |
|---|---|---|
| 40 mm (Class B wearing) | ~10.8 m² | ~9.3 tonnes |
| 50 mm (Class A wearing) | ~8.6 m² | ~11.6 tonnes |
| 75 mm (base course) | ~5.7 m² | ~17.4 tonnes |
| 100 mm | ~4.3 m² | ~23.2 tonnes |
Calculation Formula
- Volume (m³) = Length (m) × Width (m) × (Thickness in cm ÷ 100)
- Weight (kg) = Volume × 2,322.7
- Tonnes = Weight ÷ 1,000
Worked Example: 1 km × 7.3 m Road, 50 mm Wearing Course
- Volume: 1,000 × 7.3 × 0.05 = 365 m³
- Weight: 365 × 2,322.7 ≈ 847,786 kg
- Tonnes: ≈ 848 tonnes
- With 10% buffer: ≈ 933 tonnes
Project Planning Notes for Pakistan
- Monsoon avoidance: July–September rainfall disrupts paving; plan October–May.
- Bitumen quality: source from approved refineries (NRL, PRL, PARCO) for NHA jobs.
- Sales tax: typically added on top of quoted material price.
- NHA / provincial specs: always confirm gradation, binder content and compaction targets.
Frequently Asked Questions
What is the price of asphalt per tonne in Pakistan?
Asphaltic concrete typically costs ₨28,000–₨42,000 per tonne delivered, varying by region, crude oil price and exchange rate.
What density is used for HMA in Pakistan?
The reference density is 2,322.7 kg/m³ for dense-graded mixes, in line with international standards.
How much bitumen for 1 km of standard road?
A 7.3 m wide, 50 mm wearing course = ~365 m³ ≈ 848 tonnes asphalt mix. With 10% buffer ≈ 933 tonnes.
Which bitumen grade is used in Pakistan?
60/70 penetration grade is standard for most regions; 80/100 used in colder northern areas.
