India metro rail project :
In today’s technological world, an ongoing large construction project is India metro rail project.
Here I will be discussing on India metro rail project in detail.
Introduction :
New metro rail (that is Subway) systems present are in under construction and bringing about so many changes in more than 15 Indian cities.
Important key figures :
- Length of the operational rout: 673.2 kilometre
- length of under construction route: 467.87 km
- Length of the approved route: 457.56 km
Interesting fact:
- First oldest metro rail system: Kolkata Metro
- Newest metro rail system: Nagpur Metro
- Largest metro system: Delhi Metro
- Smallest metro system: Ahmedabad Metro

A clayey soil generally has a low CBR value (less than 8). Sands are more granular and drain better and will generally have CBR values between 15 and 35. Gravel will have the best CBR values, generally 25 and up. That is why it is suggested to save the best material to cap the subgrade.
