Areas of New Zealand are running out of premium aggregates that meet the demanding specifications used in unbound granular road construction. Stabilising aggregate provides a viable alternative to using premium aggregates.
The objective of this project was to improve the sustainability of New Zealand roads via a combination of accelerated pavement tests at the Canterbury accelerated pavement testing indoor facility (CAPTIF) in 2007/08 and 2008/09, and a limited field review of the performance of bound stabilised pavements.
A number of recommendations have resulted from this research concerning the design, testing and construction of modified and bound pavement layers.
