Geologic Inventory of North Island Aggregate Resources: Influences on Engineering Materials Properties, by Prof. Philippa Black, Geology, School of the Environment, University of Auckland.
This report was prepared in conjunction with a working group consisting of members of Roading New Zealand’s Pavements Committee and representatives from the NZ Aggregates & Quarries Association. It was funded by the Foundation for Research Science and Technology (FRST) under the Optimising Physical Resource Use and Infrastructure Portfolio.
Prof. Black’s report discusses the major geological types of North Island aggregates, their locations, and the indicative ranges of their engineering properties. The findings will increase engineers’ knowledge and appreciation of the geological considerations of aggregate performance. The report includes a critical review of current test procedures.
As well as enabling the development of a consumer-oriented aggregate inventory, the knowledge gained through this project should have environmental benefits by strengthening interest in marginal aggregates, thereby conserving a non-renewable total aggregate resource. A second objective of the project is to determine the relationships between geological material properties and aggregate production properties.
A South Island inventory is underway and due for completion later this year.
