This report reviewed overseas and Australian experience in using bitumen emulsions. Increasing economic and environmental pressures have induced an increase in demand for the use of bitumen emulsions overseas. However, emulsion sprayed seals are…

A review of bleeding or flushed seals was undertaken to determine what physical changes had taken place within the seal that had resulted in the binder lying at or close to the surface. The evaluation process used a visual appraisal and a digital…

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…

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…

This document provides advice for users designing asphalt mixes using the Austroads mix design procedures. The advice given should enable users to produce repeatable and valid results. The tests covered in this document are

This report documents the assessment of RSL of pavements where the RSL is confined in its estimation to the occurrence of the next major intervention either by rehabilitation or replacement. There are many measurable surface distress conditions,…

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…

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…

This document provides some guidelines on the estimation of measurement uncertainty and sampling variation. The procedures are demonstrated through a worked example based on a soil moisture content test. Estimation of the standard deviation for each…

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…
