Trends and changes in chipsealing in New Zealand

An analysis of the age of chipseals when they are resealed on New Zealand state highways shows that, despite increasing traffic stress, there has been no significant reduction in chipseal life. This paper presents data on chipseal lives, compared with changes in traffic volumes, over a 15 year period. Trends, including the date of the introduction of the different initiatives are analysed. Different initiatives covered include the change from single coat to predominantly two coat chipseals, changes in contract types from traditional to predominantly performance based maintenance contracts, and the introduction of a skid resistance policy. An analysis is made of reasons for resealing and other concepts that may have contributed to chipsealing life remaining substantially the same despite long term continued growth in traffic stress on the state highway network.
