Cut and Fill in earthmoving is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments, so minimizing the amount of construction labor. Cut and Fill technique is widely practiced in earthwork project.
Cut slopes are rarely created greater than a slope of two to one (horizontal to vertical dimensions). Cut sections of roadway or rail are characterized by the roadway being lower in elevation than the surrounding terrain. From an operational standpoint there are unique environmental effects associated with cut sections of roadway. For example, air pollutants can concentrate in the ‘’valleys’‘ created by the cut section. Conversely noise pollution is mitigated by cut sections since an effective blockage of line of sight sound propagation is created by the depressed roadway design.
Fill sections manifest as elevated sections of a roadway or trackbed. Environmental effects of fill sections are typically favorable with respect to air pollution dispersal, but in the matter of sound propagation, exposure of nearby residents is generally increased, since sound walls and other forms of sound path blockage are less effective in this geometry.
There are a variety of reasons for creating fills, among them reduction of grade along a route or elevation of the route above water, swampy ground, or areas where snow drifts frequently collect. Fills can also be used to cover tree stumps, rocks, or unstable soil, in which case material with a higher bearing capacity is placed on top of the obstacle in order to carry the weight of the roadway or railway and reduce differential settlement.
