1) Introduction
Introduction: Viscosity of VG 30 Bitumen
The introduction: Viscosity of VG 30 Bitumen is central to understanding its performance in urban road networks. Roads are essential public spaces, facilitating connectivity, commerce, and social activities. High-quality bitumen ensures durability, prevents premature wear, and enhances safety. VG 30 bitumen is specifically engineered for these purposes, offering a balanced performance in temperate climates. Its thermoplastic nature allows it to remain hard in cold temperatures and flexible in warmer conditions, optimizing asphalt integrity.
This section sets the stage for a detailed discussion of VG 30 bitumen’s viscosity, key applications, and its role in modern infrastructure, transitioning smoothly to a technical breakdown of viscosity measurements.

2) Viscosity of VG 30 Bitumen
Viscosity of VG 30 Bitumen
VG 30 bitumen’s viscosity defines how it behaves under varying temperatures and loading conditions.
SEO Snippet: VG 30 bitumen’s viscosity ensures optimal flexibility in asphalt, preventing cracking and extending pavement lifespan.
Viscosity is a fundamental property determining bitumen flow at different temperatures. VG 30 is measured at 60°C (absolute viscosity: 2400–3600 cP) for summer track conditions and at 135°C during asphalt mixing. Proper viscosity ensures asphalt mixes perform reliably, resist fracture, and withstand traffic loads. Construction failures often stem from inadequate understanding of viscosity, improper methods, or unsuitable environmental conditions. VG 30’s rheological properties influence oxidation rate and erosion, essential for long-term pavement performance.

3) Why VG 30 Bitumen is Used
Why VG 30 Bitumen is Used
VG 30 bitumen is preferred for high-traffic roads, sidewalks, and heavy-load pavements due to its durability and thermoplastic properties.
SEO Snippet: VG 30 bitumen provides a durable, temperature-resilient solution for road construction and urban pavement projects.
VG 30 is a refinery-grade viscosity bitumen produced through vacuum baton aeration. Its thermoplastic nature allows it to harden in cold temperatures while softening in hot weather, enhancing asphalt mix durability. Compared to penetration bitumen, VG 30 ensures precise grading and performance consistency. It is extensively used in super-heavy asphalt pavements, high-load sidewalks, urban streets, and in industries such as building construction, insulation, and liquid bitumen manufacturing. VG 30 is particularly suited to temperate climates and is a reliable alternative to 60/70 penetration bitumen.
