The reddish colour of these soils is imparted by the iron compounds. Murrum are residual soils and are formed from weathering of basaltic rock at places, where monsoon is severe (Ketkar, 1970). They constitute mixture of weathered rock pieces in varying sizes, sand, silt and clays. They are good material for road construction.

Shrinkage = volume after compaction/volume before excavation. Both the loose and compacted volume are calculated from the bank volume. Example: If you are excavating dry clay it is listed as having a swell of 50% and a shrinkage of -10%. That means that for every 1 cubic metre/yard of material that you excavate the volume increases by 50%.
