Accurate testing for performance, quality, and compliance of bituminous materials.
METS Lab provides comprehensive Bitumen Analysis Services to ensure that bituminous materials used in construction, road paving, and waterproofing applications meet the required national and international standards. With our state-of-the-art laboratory and experienced technical team, we support industries in maintaining quality, enhancing durability, and achieving regulatory compliance.
Whether you are sourcing bitumen, manufacturing asphalt mixes, or involved in infrastructure development, we help you verify the quality and suitability of your material.
Why Bitumen Testing is Essential?
Bitumen, a viscous petroleum-based binder, plays a critical role in road construction, roofing, and industrial applications. Its performance directly impacts the lifespan, strength, and weather resistance of the end product. Improper or substandard bitumen can result in:
- Cracking and deformation of pavements
- Early road surface failure
- Poor water resistance and adhesion
- Regulatory non-compliance and project delays
Our testing services help prevent such issues by providing accurate insights into bitumen properties, composition, and performance behavior under various environmental conditions.
Bitumen Types We Test:
- Penetration Grade Bitumen (e.g., 60/70, 80/100)
- Viscosity Grade Bitumen (VG 10, VG 30, VG 40)
- Polymer Modified Bitumen (PMB)
- Emulsified Bitumen
- Cutback Bitumen
- Oxidized (Blown) Bitumen
Key Tests Offered:
- Penetration Test (ASTM D5) – Measures hardness and consistency
