This is the first session in a series of three webinars to present the findings of the report Prolonging the Life of Road Assets Under Increasing Demand: A Framework and Tools for Informing the Development and Justification of Asset Preservation and…

This report provides an evaluation framework, practices and supporting tools for evaluating road preservation and renewal treatment options for predominantly sprayed seal flexible pavements. It includes a compilation of case studies based on a…

This report details the experimental program, analysis and findings of the assessment of the impacts of axle mass increases on road deterioration for sprayed seal surfaced unbound granular pavements. Load-damage exponents ranged between two and four…

This document describes the results of field trials held in Christchurch, New Zealand in May 2005. The objective of the trials was to gain further understanding of the complex relationship between the various test devices currently utilised to…

Selection of maintenance techniques is always a balance between the administering authority costs and social and environmental costs and outcomes. This project provides practical information and a methodology (including a worked example) for…

A general literature survey and a user survey was conducted to obtain information on existing data aggregation methods and their status in Australia and New Zealand. The responses to the survey indicated that all agencies use or are close to…

An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…

An existing model predicted maximum seal life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters and binder durability (resistance to hardening).…
