Guide to Pavement Technology Part 4J: Aggregate and Source Rock
Part 4J of the Guide to Pavement Technology provides information and guidance on: the classification and description of source rocks
The Development and Evaluation of Protocols for the Laboratory Characterisation of Cemented Materials
The study involved a laboratory assessment of two cemented materials to assess their strength, modulus and fatigue properties. The cemented materials consisted of a hornfels crushed rock and a quartzite siltstone bound with general purpose cement at…
Relative Pavement Wear of an Unbound Granular Pavement due to Dual Tyres and Single Tyres
This report presents the results of testing conducted on an unbound granular pavement with a thin bituminous surfacing using a variety of tyre types and half-axle loads applied using the Accelerated Loading Facility. It was found that the reference…
Fatigue Performance of Cemented Materials under Accelerated Loading: Influence of Vertical Loading on the Performance of Unbound and Cemented Materials
This research involved a performance assessment of two cemented pavement materials using the Accelerated Loading Facility (ALF) to simulate heavy axle loading. The assessment involved a number of axle loads from a standard half axle load of 40 kN to…
Development of HDM-4 Road Deterioration (RD) Model Calibrations for Sealed Granular and Asphalt Roads

Improved RD models for sealed granular and asphalt pavements are needed. Pavement performance history data from state road authorities and New Zealand (SRAs) were used for calibrating RD models. The calibration and refinement of RD models is…

Optimum Use of Granular Bases: Construction of Test Pavements

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…
