Ep. 01 CBR Test Explained (IS 2720 Part 16 / AASHTO T193) | Scope, Significance & Use in Highway |

Описание: 👷‍♂️ Namaskar Engineers!
Welcome to another episode of our Highway Material Testing Series!
In this video, we are starting with the CBR Test – California Bearing Ratio, as per IS 2720 (Part 16):1987 / AASHTO T193.

📘 In this Episode, You’ll Learn:
✅ What is the Scope of the CBR Test — where and why it is used.
✅ Which materials can be tested — subgrade, sub-base, and base course materials.
✅ What are the Referenced Standards like T99, T180, T265 etc.
✅ How water content and dry density affect the CBR value.
✅ Why soaking is done before penetration.
✅ Significance & Use — how CBR is applied in flexible pavement design as per MoRTH & IRC.

🧪 This episode gives you a clear understanding of:

Why we modify material passing 19 mm sieve,

How compaction and moisture affect strength,

And why CBR is critical for highway foundation design.

🎯 Perfect for:
Students | Site Engineers | Quality Control Labs | Highway Professionals
