🧪 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।
