Research report 401 Rationalisation of the structural capacity definition and quantification of roads based on falling weight deflectometer tests

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

Pavement performance modelling for New Zealand roading networks, currently relies on an adjusted structural number (SNP) which is a single parameter intended to describe the performance of a multi-layered pavement structure in terms of its rate of de…

Research Report 384 Tyre/road contact stresses measured and modelled in three coordinate directions

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

To enable the improvement of the modelling of pavement response and performance, the measurement of full-scale tyre surface contact stress distributions in all three of the coordinate directions was undertaken.

Research Report 372 Resealing strategies to increase seal life and prevent seal layer instability

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

A study of cores from multilayer chipseals shows that fine solid materials (passing 4.75 mm) fill a significant proportion of the chipseal volume that would otherwise be available for bitumen.

Research Report 175 Effects of multiple presence & monitoring period on bridge health monitoring

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

Bridge health monitoring is a method of evaluating the ability of a bridge to perform its required task (also called fitness for purpose) by monitoring the response of the bridge to the traffic loads it has to withstand.
