Chipsealing in New Zealand

Published: | Category: Manuals , Pavement design | Audiences: Road traffic engineers & consultants, Roading contractors

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. In New Zealand extremes of climate and landscape impose many constraints on road surface performance and present challenges to be overcome. Chipsealing techniques differ from the north to the south of New Zealand and there is therefore no 'correct' or only way for a chipsealing operation to be carried out. Experience and research are presented in this book so the reader can make their own informed decisions when using chipsealing technology. This book is intended for those studying road engineering at polytechnic or university level and for those already in the chipsealing industry who want to broaden their knowledge, or those from another line of engineering to...

Specification for the manufacture and construction of plant mixed bound sub-base pavement layers

Published: | Category: Specifications , Pavement & surfacing | Audiences: Road traffic engineers & consultants, Roading contractors

Stabilisation of pavement layers has a long history in New Zealand. Stabilisation is becoming more common as increasing traffic volumes and higher axle load limits are driving the need for pavements that are more robust than traditional unbound pavements. Equally in areas where top quality aggregates are hard to justify/find – these processes can provide economically viable alternatives.

Unsealed pavements: digout repairs

Published: | Category: Specifications , Maintenance | Audiences: Road traffic engineers & consultants, Roading contractors
