The object of this study was to gather data on the levels of bitumen oxidation found in dense asphalt surfacings.

There have been a number of high-profile early failures in New Zealand pavements (rut depths greater than 20mm observed early in the pavement life) associated with ‘greenfield’ pavements (pavements not subjected to traffic during construction).

Investigations into the cohesive properties and oxidation resistance of an acid-cured, epoxy-modified open-graded porous asphalt (EMOGPA) were undertaken, and an associated field trial constructed on State Highway 1 in Christchurch in December 2007.

This research develops an assessment tool and provides initial findings of whether RCAs are meeting their obligations under the Civil Defence and Emergency Management (CDEM) Act 2002, which states that the road network, among the other lifelines util…
