assessing relative risks to receiving waterbodies using estimates of copper and zinc from road traffic and nonroad (urban) sources. Risk levels are evaluated using contaminant strength and receiving environment sensitivity scores with streams/rivers

geotextile selection and usage. The uses of geotextiles in pavements of both sealed and unsealed permanent roads are discussed, as is the use of geotextiles in pavement construction, and in unsealed temporary roads. Filtration is covered in some

Stabilisation of pavement layers has a long history in New Zealand. Stabilisation is becoming more common as increasing traffic volumes and higher axle load limits are driving the need for pavements that are more robust than traditional unbound

Bridge health monitoring is a method of evaluating the ability of a bridge to perform its required task (also called fitness for purpose) by monitoring the response of the bridge to the traffic loads it has to withstand. This research project

Vehicular traffic on road asphalt generates a variety of inorganic and organic contaminants. These accumulate on the road surface in quantities that depend on the traffic and road conditions. During rainfall events, they are washed from the road

This report describes a New Zealand study of the effect of different binders on the rate of chipseal texture loss under traffic. Work to measure the adhesive and rheological (flow) properties of different binders is described. Several chipseal

Specialist surfacings such as highfriction and coloured trafficcalming surfaces have gained huge popularity since their introduction. However, the reputation of these specialist systems in New Zealand is also plagued by premature failures due to
