🧪 Temperature Control in Bituminous Road Construction – Complete Practical Guide for Site Engineers
Introduction
Bituminous road construction (DBM, BC) में temperature control सबसे critical factor है। अगर temperature सही नहीं है, तो road जल्दी fail हो सकती है।
👉 “Right Temperature = Strong Bonding = Long Life Road”
इस article में हम temperature control को plant से site तक practical तरीके से समझेंगे।
Why Temperature Control is Important?
Proper bonding के लिए
Compaction achieve करने के लिए
Durability improve करने के लिए
Temperature Stages in Bituminous Work
1. Mixing Temperature (Plant)
150°C – 170°C
👉 Aggregate + bitumen proper mix होना चाहिए
2. Transportation Temperature
Heat loss avoid करें
Trucks cover करें
3. Laying Temperature
120°C – 140°C
👉 Paver पर correct temperature maintain होना चाहिए
4. Compaction Temperature
90°C – 110°C
👉 Low temperature = poor compaction
Temperature Measurement Tools
Infrared Thermometer
Contact Thermometer
Step-by-Step Temperature Control Process
1. Plant Monitoring
Mixing temperature check करें
Overheating avoid करें
2. Transportation Control
Cover trucks
Delay avoid करें
3. Site Checking
Paver पर temperature check करें
हर load verify करें
4. Rolling Timing
सही समय पर rolling शुरू करें
Delay avoid करें
Common Problems
Problem 1: Low Temperature
👉 Result: Weak bonding
Problem 2: High Temperature
👉 Result: Bitumen damage
Problem 3: Delayed Compaction
👉 Result: Poor density
Site Engineer Responsibilities
Temperature monitoring
Record maintain करना
Quality ensure करना
Practical Tips
✔ Temperature gun हमेशा रखें
✔ Continuous paving करें
✔ Cold joints avoid करें
Conclusion
Temperature control bituminous road construction का सबसे critical factor है। Proper temperature maintain करने से road strong और durable बनती है।
