farm track

Cows should be encouraged to move away from the shed after milking, as accumulated manure will form a barrier to drainage off the edge of tracks and track breakdown can occur.

The track should be crowned to shed water, with an average cross fall between 3 and 6 percent and a suggested maximum of 10%.
The types of soils used in construction of these tracks (at Maffra in Victoria) have increased compressive strength (measured in the laboratory) when well compacted at optimum moisture content. The addition of only 3% cement or lime further increases compressive strength.

Even well constructed farm tracks require regular maintenance if they are continue to function effectively. As cows use tracks, it is common to see manure and track debris being carried onto the edge of the track and preventing water draining away from the track into the purpose constructed drains.
Cows walk considerable distances when grazing. In primarily pasture-fed dairy herds these distances increased significantly as herd size increases.
Another suggestion (Roger Wrigley) is that the width of track can be based on allowing one metre in width for each 20 cows up to a maximum 8 m in width.
The junction between a concrete apron extending from the milking yard and the farm track should be sloped so that the concrete runs back from the junction towards the milking yards and the track falls away from the junction between the concrete apron and track. The junction between the concrete apron and the farm track is then the highest point and water will drain away from this area
Moisture absorption, measured by soaking prepared specimens in the laboratory for 24 hours, generally increased when maximum density was not achieved.
