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…

The majority of sprayed seal design methods around the world are based on the work of Hanson, published in 1935. However, there are growing weaknesses in current sprayed seal design models. Traffic loads have increased, particularly in both the…

Cooperative Intelligent transport systems (C-ITS) is an emerging platform that can be applied to motor vehicles and roadside infrastructure to enable direct two-way communication between them. Because C-ITS enables connectivity between road users…

The Cooperative Intelligent transport systems (C-ITS) platform is being designed to make a substantial contribution to moving people and goods safely and efficiently. This will be achieved by connecting road users in their vehicles to their road…

The purpose of this report is to identify new technologies that are potentially useful for asset managers and develop guidelines for the application of selected new technologies for asset/risk management. This report covers the first stage of the…

This report investigates the provision of facilities for bicycles on sealed roads with speed limits of 70 km/h or more. It outlines how to improve these roads for cyclists where off-road alternatives or on-road, lower speed, direct options are not…

This report has developed a new index, the Heavy Vehicle Roughness Band Index (HVRBI), as a measure of ride quality for heavy vehicles. The HVRBI is intended for use by road asset managers as a trigger to initiate pavement intervention works…

Bitumen is a major component used in the construction of roads in Australia and New Zealand. As it can only be manufactured from a small number of the crude oils in the world, the future supply and cost of bitumen will be directly linked to the…

This report develops approaches that estimate the marginal cost (MC) of bridge wear for heavy vehicle usage and estimates the availability and reliability of the data needed to use these approaches. Two approaches were examined. The first was an…
