Bitumen Heating Temperature Kya Honi Chahiye?
Most Common Site Mistake Explained
Quick Answer: Bitumen ko sahi temperature par heat karna bahut zaroori hai. Overheating se material damage hota hai aur road life kam ho jati hai.
🌡️ Ideal Temperature Range
VG30 / VG40 → 150°C – 165°C
PMB → 160°C – 170°C
CRMB → 170°C – 180°C
⚠️ Sabse Badi Galti (Most Common Site Mistake)
❌ Direct flame heating se bitumen jal jata hai, viscosity change ho jati hai aur performance gir jata hai.
👉 Dikhta same hai, lekin road performance drastically gir jata hai.
🚧 Overheating Impact
❌ Binding weak
❌ Early cracking
❌ Rutting risk increase
❌ Road life kam
🛠 Best Practices (Site Par Kya Karein?)
1
Thermometer use karo (guess mat karo)
2
Indirect heating system use karo
3
Continuous stirring maintain rakho
