Followed by thin layer of 5mm fine chippings. This is in contrast to the design value ofesa over a ten year design life. Consequently there is a need for a 2t2cn of rural road design standards based on the actual and anticipated tasks they will be asked to perform in terms of vehicles, axle loads and traffic volumes, rather than being based on an administrative classification.
