This specification (2012) and guidance notes outline the process for identifying sites where treatment to improve skid resistance may be justified and the process to be followed. In addition, previous versions of the T10 specification (1997, 1998, 1999, 2002 and 2010) and notes (1997, 1998, 1999 and 2002) are listed as historical references.
Note: Use is mandatory on state highways and may be appropriate for some sections of other road controlling authority roads.
These guidelines for surfacing treatment selection have been written for asset managers, surfacing engineers and pavement designers. They aim to guide the reader in the engineering decision making and processes that need to occur in selecting a road surfacing treatment.
This guide has been produced to inform roading practitioners, contractors and the public about how road surfaces affect noise levels and what low-noise road surfaces are available in different situations. Information is also provided on maintenance issues and basic engineering considerations.
Chipsealing in New Zealand is a distillation of information from at least 80 years experience in New Zealand, compiled by chipsealing experts from throughout New Zealand. Many years of experience based on research and backed up by references have contributed to this book.
By John Patrick, Joanna Towler, Peter Howe. Presented 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.
