Kerb and channel practices - use of machines and standardisation

Mechanical kerb and channel extrusion machines have improved to the extent that the machines are now capable of producing large lengths of accurately formed kerbing using a minimum of labour. The machines, although being more sophisticated, are relatively simple to operate and the speed of production relies to a large extent on the accuracy of the subbase upon which the concrete is to be laid. The machines are most applicable for large scale work such as on freeways or arterial roads as the initial cost and high rates of production would preclude their use in other circumstances. In addition the width of the machine would make its use difficult in situations where an existing road pavement was to be retained, and the delays due to having to stop for vehicle driveways and side entry pits would severely cut production rates.
