Presented by John Patrick, Joanna Towler, and Peter Howe at the 2nd International Sprayed Sealing Conference – sustaining sprayed sealing practice, Melbourne, Australia 2010. 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.
