Railways & Metro Rail
Highways and Railways serve as lifelines of any developed or developing country. To build and to construct roads, highways and railways, Expanded Clay Aggregate (ECA ®) or Lightweight Expanded Clay Aggregate is being used as a light fill material to reduce subgrade settlement and to improve stability of structure and the surrounding area. Expanded Clay Aggregate (ECA ®) or Lightweight Expanded Clay Aggregate is also used for the purpose of development of pedestrian and bicycle tracks, rail yards and railway platforms.
Expanded Clay Aggregate (ECA ®) or Lightweight Expanded Clay Aggregate is applied to construct or to repair settlement defects, to increase levelling and to improve bearing capacity on highways and railways including metro or tubes.
Importance Of Expanded Clay Aggregate (ECA ®) In Construction Of Railways, Metro Rail and High-speed Rail ( Bullet Trains )
-
Improves stability of surrounding area and structures
-
Serves as a light fill material to reduce subgrade settlement
Usefulness Of Expanded Clay Aggregate (ECA ®) in the Reconstruction of Railways, Metro Rail & High-speed Rail ( Bullet Trains )
-
To correct settlement defects
-
To improve load-bearing capacity
-
To increase leveling precision?
Designing Objectives Expanded Clay Aggregate (ECA ®) Layers:
-
To block capillary action due to water rise
-
To provide excellent thermal and sound insulation
-
To function as an excellent drainage layer
Expanded Clay Aggregate (ECA ®) Improves the Stability of Soil by Minimizing the Load Impact :
Properties To Be Considered
-
Ground water and open water level
-
Pore water pressure
-
Live and dead loads
-
Inclination of soil layers or ground surface or soil layers
-
Adjacent foundations and buildings
-
Required safety factor of structure against collapse
