Dependant on proposed
use of the highway would depend on the specification
of the construction of the roadway. The heavier
the traffic proposed, would depend on thicknesses
and specification of sub base.
As with sub bases the thickness
and specification of macadam’s would also
vary. The majority of roadways would need to be
constructed using a retaining curb or edging,
again dependant on traffic expected would depend
on specification of curbs and edgings. |
