STV COMPACTION:
Triple Compaction for a Flawless Pavement
🎯 Objective: Achieve a uniform and durable surface finish through advanced compaction technology.
🔍 Technical Focus: STV System (Strike-Off / Tamper / Vibrator)
🔊 Triple compaction: the key to deep, efficient compaction
Compaction is not just about the surface – it’s about transmitting energy deep into the mix to eliminate air voids and enhance interlayer bonding. In this module, you’ll learn how to:
• Adjust vibration frequency and amplitude based on material type
• Achieve more uniform, long-lasting compaction
• Reduce the number of roller passes, saving time and fuel
• Avoid surface damage caused by over- or under-compaction
A well-managed vibration process improves surface quality, optimizes energy use, and pr
🔧 Functional Focus: STRIKE-OFF – MATERIAL PRE-COMPACTION
🧪 Preparing the material: the foundation for perfect paving
Good results start with proper preparation. The strike-off distributes and pre-compacts material to reduce shifting and ensure evenness. It’s the first step in the STV system.
👉 Why is it useful?
• Prevents material build-up in front of the tamper
• Prepares the mix for optimal compaction
• Minimizes surface defects
👉 Operational Advantages:
• Better material layout
• Higher surface quality
• Easier follow-up compaction
🔧 Functional Focus: TAMPER – INTERMEDIATE COMPACTION
🧱 Effective compaction, reduced energy use
Tamper action follows strike-off, delivering intermediate compaction with minimal energy. Learn how to balance power and precision for strong density at lower cost.
👉 Why is it useful?
• Improves stability and density
• Reduces air voids in the mix
👉 Operational Advantages:
• Low energy consumption
• More compact, even surface
• Less need for final rolling
🔧 Functional Focus: VIBRATOR – FINAL COMPACTION
🔊 Final compaction for a perfect finish
The last stage is critical. The vibrator ensures surface uniformity and durability by eliminating residual inconsistencies and perfecting the finish.
👉 Why is it useful?
• Enhances surface finish and durability
• Ensures consistent results across the width
👉 Operational Advantages:
• Uniform compaction in difficult conditions
• Reduced fuel consumption and wear
• Extended pavement life
🛠️ Operator Tips:
• Check all STV system components before use
• Use all three compaction stages for top performance
• Adapt settings to site conditions and material type
