Pavement maintenance management in New Zealand: report from a brief visit in August, 1979

A brief outline of the management structure for road construction and maintenance in New Zealand is presented. Maintenance management and programming techniques in use by the Ministry of Works and Development are described. Two systems of pavement condition monitoring are used in New Zealand. A pavement structural rating system, recording 10 indicators of pavement condition, has been in use since 1969. A more detailed 'walkover' inspection technique is used by local supervisory staff to itemise and schedule work items for the incoming financial year. In addition the use of cost benefit analysis to confirm the validity of recommended 'major' works is utilised. Some significant points of discussion identified by the author at various sessions of the New Zealand roading symposium, 1979, are discussed. Several sessions recorded discussion on the increasing need for fund allocation in the roads section of the economy to be shown to be competitive with fund requirements in other sections. A recommendation that analysis of the nz pavement structural rating survey information for the past ten (10) years may be advantageous in supplementing Australian data is made. Although data collected in Australian surveys is generally more comprehensive than those obtained in nz, the identification of the rate of development of the different distress conditions may well be available from the nz data. This information is not yet available from Australian surveys due to their short term of operation (a).
