MS-2 Chapter 5 Epi No-26 “Aggregate Blend ka Gsa aur Absorption kaise nikale? | Asphalt Mix Design”

In asphalt mix design, Bulk Specific Gravity (Gsb) testing also helps us determine two very important aggregate properties — Apparent Specific Gravity (Gsa) and Water Absorption.
In this video, we clearly explain Clause 5.3.5 – Calculate the Gsa and Absorption for the Aggregate Blend in a simple, site-friendly Hindi + English (technical) manner.

In this video, you will learn:

What is Apparent Specific Gravity (Gsa)

What does Water Absorption indicate about aggregate quality

Why high absorption aggregates need extra binder

How 40–80% binder absorption affects mix cost

How Gsa & absorption are calculated when:

Gsb is tested on individual stockpiles

Gsb is tested on coarse and fine fractions

Gsb is determined directly from aggregate blend

Which equations from Section 5.3.3, 5.3.4, and 5.3.5.2 are used

📌 Useful for:
Asphalt Mix Design Engineers | Highway Engineers | Lab Technicians | QC Engineers | PRA / MoRTH / ASTM Students

📌 Language: Hindi (Devanagari) + English technical terms
📌 Focus: Practical understanding + field application

👉 Watch till the end to understand why absorption directly affects binder demand and project cost.
