Areas of New Zealand are running out of premium aggregates that meet the demanding specifications used in unbound granular road construction.

Research Report 491 Factors influencing the decision to rehabilitate a pavement

Published:
Category: Activity management , Research programme , Research & reports | Audience: General

The objective of this research, undertaken in 2008–11, was the development of an improved method of modelling the decision to rehabilitate a typical New Zealand thin-surfaced unbound granular pavement.

Research report 470 Selection of aggregates for skid resistance

Published:
Category: Activity management , Research programme , Research & reports | Audience: General

Statistical modelling was undertaken to develop a means for reliably predicting the expected in-service skid resistance of any rural section of the New Zealand state highway network surfaced with chip seal.
