Construction of embankment, Civil Engineering

Construction of Embankment:

The following steps describe embankment construction :

(a) The ground is cleared and grubbed and all vegetation, grass, roots, etc. are removed.

(b) The original ground, if loose, is compacted by loosening the soil, adding water and rolling.

(c) The embankment soil is deposited in layers of about 25 cm loose thickness so as to get a compacted thickness of not higher than 15 cm.

(d) The moisture content in the soil should be brought to the optimum, by adding extra water or allowing the moist soil to aerate.

(e) Rolling is done by a road roller giving sufficient number of passes such that the desired density is achieved.

(f) The alignment, cross-section and levels are controlled by previously set temporary Bench Mark pillars and pegs.

(g) It is a good practice to construct the layers of the embankment also to the final camber/cross-slope of the pavement.

(h) The top 300-500 mm of the embankment, known as the sub-grade, is generally made up with soils which are better than that used in the body of the embankment. The density to which the sub-grade soil is compacted is also higher than in the rest of the embankment.
