What is diffrence between retaining wall and breast wall?
Relative compaction is a ration of the density of soil at site to the maximum dry density of soil. like we have maximum dry density of soil have 1800 kg/m3 which determine in lab now on site we can archive 1700 kg/m3 by compaction of dumped soil so relative density of that soil on site is =1700/1800Read more
Relative compaction is a ration of the density of soil at site to the maximum dry density of soil.
like we have maximum dry density of soil have 1800 kg/m3 which determine in lab
now on site we can archive 1700 kg/m3 by compaction of dumped soil
so relative density of that soil on site is =1700/1800=0.9444 = 94.44%
it is use for
- to know how much density we archive compare to design in lab
- sometime in specification minimum criteria of relative density are given, ex- minimum relative density at whole site should be 90%.
- from relative density we can calculate actual movement of soil, which is very important in tall building and structural durability calculation

In hill. When road is construct, at that time we need to cut-off some portion of hill and basically we construct two wall one is breast wall which is on hill side of the road to give stability of hill slop and another one is retaining wall which is construct on valley side of road which wall have backfill pressure plus road pressure on backfill so we need to design retaining wall for that backfill & surcharge .
