📝 YOUTUBE VIDEO DESCRIPTION (SEO + Explanation Friendly)
In asphalt mix design, calculating the Bulk Specific Gravity (Gsb) of the aggregate blend is a critical step for accurate volumetric analysis.
In this video, we explain Clause 5.3.4 – Calculate the Gsb for the Aggregate Blend in a simple, site-friendly Hindi + English (technical) format.
You will learn:
What is Bulk Specific Gravity (Gsb)
Why individual stockpile Gsb is combined
How Equation 5.6 works
Why Weighted Harmonic Mean is used instead of arithmetic mean
Practical field verification using 4.75-mm sieve
Real numerical example (Eq. 5.7) with two stockpiles
This video is very useful for:
Asphalt Mix Design Engineers
Highway & Pavement Engineers
Lab Technicians
Students preparing for PRA / ASTM / MoRTH / IS Codes
📌 Language: Hindi (Devanagari) + English technical terms
📌 Level: Beginner to Intermediate
📌 Use Case: Lab + Field Quality Control
👉 Watch till the end to clearly understand why Gsb uses Weighted Harmonic Mean and not simple average.
