Technical advice note
Road controlling authorities,
Road traffic engineers & consultants,
The Austroads Guide to pavement technology part 2: pavement structural design and the associated New Zealand supplement (Transit 2007) are used to design pavements in New Zealand. These documents consider the effect of vertical stresses at the pavement surface, and the impact on the tensile strains at the bottom bound layers (asphalt or cemented materials) and compressive strains at the subgrade level.
