Polished aggregate friction value (PAFV) tests are used by most jurisdictions in Australia to determine the resistance of aggregates to the polishing action of vehicle tyres on the road. Two versions of the PAFV test are used in Australia: the…

This report describes studies of the effects of test conditions on vertical polished aggregate friction value (PAFV) results and the results of a proficiency study which was conducted to determine a preliminary PAFV value for UK aggregate. The…

Cutting solvents have been traditionally added to binders used in sprayed sealing in Australia and New Zealand to ensure that effective adhesion occurs between binder and aggregate. Recent Polymer modified binder (PMB) sealing failures, which have…

The work described in this report determines updated cutter level recommendations for S10E and S20E binders. Studies were also conducted to investigate the relationship between the contact angle of water on films of bitumen and PMB binders, and…

This study looked into four on-road public transport (ORPT) priority treatments including: full bus lane (FBL), set back bus lane (SBBL), queue jump bus lane (QJBL) and no priority (NP). Microsimulation traffic modelling (MSTM) is a useful tool for…

Accessibility is broadly defined as the variety of opportunities provided to people through efficient arrangement of land use and various modes of transport. It measures the ease with which people are able to find and reach the best suited…

This paper considers how several recent pedestrian-oriented bridges, all on Auckland’s Western Ring Route, provide new connections or re-establish severed connections between communities. As the architect involved in these bridges, I will also…

Priorities in bridge engineering are changing. The imperative has shifted subtly from minimum cost to “more for less”, requiring a more holistic approach to sustainable delivery which offers best value to the economy and society as a whole over the…

The current practice of balancing traffic density or distributing traffic evenly in a road network is essentially subjective and is achieved manually through expert opinions. This report summarises these expert opinions and investigates whether…

This Pavement Work Tip is a practical guide for restoring texture to bleeding or flushed surfaces by applying additional aggregate with the assistance of chemical solvents.
