Airport runway pavement operates under conditions far more demanding than standard road construction. Aircraft landing gears can exert loads exceeding 900 kN with tire pressures up to 1.4 MPa — well beyond anything road bitumen faces. Selecting the correct bitumen grade is therefore not just a technical decision; it is a safety-critical requirement.
Penetration grade bitumen for airport use must deliver outstanding resistance to rutting under static and dynamic aircraft loads, high surface smoothness for safe takeoff and landing, chemical resistance to aviation fuel and hydraulic fluid spills, and long-term durability against UV oxidation and thermal cycling.
Zumrut International Kimya manufactures and exports bitumen grades specifically suited to airfield pavement construction, supplying contractors and government agencies across Asia, Africa, the Middle East, and Europe from our facilities in Turkey and the UAE.
Recommended Bitumen Grades for Airport Runways
The selection of bitumen grade for airport pavement depends on climate zone, traffic load category, and zone type (runway, taxiway, or apron). The following grades are most commonly specified under international aviation standards.
The hardest penetration grade — preferred for airport runways in warm and tropical climates. Offers maximum resistance to rutting under heavy aircraft wheel loads and high tire pressure. Specified under ASTM D946 for high-load pavements.
The most widely used penetration grade globally. Suitable for airport runways in moderate climates where temperature ranges are controlled. Provides a reliable balance between hardness and workability during laying.
Polymer Modified Bitumen (SBS-based) is increasingly specified for main runways and high-stress aprons. Delivers superior resistance to rutting, fatigue cracking, fuel spills, and extreme temperature fluctuations. Preferred by FAA for demanding applications.
Viscosity Grade 40 is preferred for airport construction in hot climates (Middle East, South Asia, Africa) where high summer pavement temperatures demand a stiffer, higher-viscosity binder to resist permanent deformation.
Airport Zones & Bitumen Application
Each zone within an airport has different structural requirements. The bitumen grade must be selected according to the specific load, movement type, and environmental exposure of each zone.
✈
High-speed landing and takeoff loads. Requires maximum rutting resistance and smooth surface texture. Grade 40/50 or PMB.
🛤
Slow-speed, high-frequency aircraft movements with heavy static loads. Grade 40/50 or VG-40 recommended.
🕠
Static aircraft parking with fuel spill exposure. PMB or chemically resistant bitumen required for durability.
🚗
Ground service vehicle routes. Standard Bitumen 60/70 or 80/100 is typically sufficient for these lower-load areas.

Applicable Standards for Airport Bitumen
Airport runway bitumen must conform to international aviation and construction standards. Zumrut supplies products that meet all major regulatory frameworks used by government agencies and international contractors.
- FAA
FAA AC 150/5370 – Item P-401
The Federal Aviation Administration’s primary specification for asphaltic surfaces on airfield pavements. Governs bitumen grade selection, mix design, and compaction requirements for runways, taxiways, and aprons. - ICAO
ICAO Annex 14 – Aerodromes
Sets international standards for aerodrome physical characteristics, including pavement surface conditions, friction levels, and structural requirements applicable to bituminous surfaces. - ASTM
ASTM D946 / ASTM D3381
Standard specifications for penetration-graded asphalt binders for pavement construction. ASTM D3381 includes provisions for cold climate cracking resistance, often specified for airports in northern regions. - EN
EN 12591 – European Standard
Applies to airport projects in Europe and countries following European norms. Covers penetration grades 35/50 and 50/70 (equivalent to ASTM 40/50 and 60/70 respectively).
Why Airport Runways Require Specialised Bitumen
Airport pavement conditions are fundamentally different from road construction in several critical respects:
Extreme Load Intensity
A Boeing 747 landing gear can apply loads exceeding 900 kN with tire inflation pressures around 1.4 MPa — compared to 0.6–0.7 MPa for heavy road vehicles. This requires a bitumen with superior stiffness and resistance to permanent deformation (rutting).
Surface Smoothness Requirements
Runways demand exceptional surface regularity measured by the International Roughness Index (IRI) and friction coefficients. Bitumen must maintain consistent texture throughout its service life to ensure safe aircraft operations under wet conditions.
Chemical Resistance
Aviation fuel (Jet-A1, Avgas) and hydraulic fluids can degrade standard bitumen at apron and gate areas. PMB and hard-grade penetration bitumen offer significantly better resistance to fuel spill attack compared to softer grades.
Thermal Stability
Airport surfaces experience wide temperature ranges — from the heat of jet engine exhaust to sub-zero winter conditions. Bitumen 40/50 and PMB maintain structural integrity across these extremes better than softer grades.
Frequently Asked Questions
Bitumen 40/50 is the primary penetration grade for airport runways, especially in warm and tropical climates, due to its superior hardness and rutting resistance. For extreme performance requirements, Polymer Modified Bitumen (SBS-PMB) is the preferred choice on main runways and high-stress aprons worldwide.
The FAA’s primary specification is Item P-401 within Advisory Circular AC 150/5370. It governs the use of asphalt binders for airfield pavements and references ASTM D946 and ASTM D3381 for bitumen grade requirements. Cold climate projects may also reference AASHTO M320 for performance-graded binders.
Generally yes — Bitumen 40/50 is used for both runways and taxiways in warm climates. However, taxiways experience more frequent slow-speed, high-load movements which increase rutting risk. In very hot climates, VG-40 or PMB may be specified for taxiways even when 60/70 is used for the runway surface course.
Yes. All Zumrut bitumen shipments include certified test reports covering penetration, softening point, ductility, flash point, and other required parameters. Third-party inspection by SGS or Geo-Chem is arranged at the loading port (Iskenderun or Dubai) upon request.
Penetration grade bitumen (40/50, 60/70) is a conventional binder suitable for standard airport pavements. Polymer Modified Bitumen incorporates SBS or EVA polymers into the base bitumen to enhance elasticity, rutting resistance, fuel resistance, and fatigue life. PMB is increasingly required for main runways at major international airports due to its superior long-term performance.
