Research Report 113 Lead-based paint management on roading structures: Section I – Results of surveys

Published: | Category: Environmental impacts of land transport , Research programme , Research & reports | Audience: General

This report is Section I of four 'stand alone' documents that can be used by road controlling authorities, maintenance engineers, and industrial painting contractors when carrying out removal or maintenance of lead-based paints on steel roading structures, to comply with their statutory obligations and minimise effects on the environment and risks to workers and public health. Section I contains the results of a survey of local and regional authorities to determine their requirements when issuing a consent for this work. The number of roading structures in New Zealand that are coated with lead-based paint are quantified. Report series

Section II - Code of conduct
Section III - Guidelines
Section IV - Model specification

Research Report 180 Cycle audit and cycle review: a scoping study

Published: | Category: Safety, security and public health , Research programme , Research & reports | Audience: General

This study was an investigation to see whether the process of cycle audit and cycle review developed by the Institution of Highways and Transportation in the United Kingdom should be introduced in New Zealand. The researchers interviewed traffic engineers and planners, road safety coordinators and cycle officers in nine local authorities, as well as cycle advocates, regional authority staff and Transit New Zealand staff. The results include: information on the safety audit processes currently used, how cyclists are considered in the design process, whether cycling is encouraged, whether cyclist safety is provided for, and whether road controlling authorities would be likely to use the process of cycle audit and cycle review. Information on how the process is being used in Britain is included. The study identifies the gaps in providing for cycling in the current design processes and makes recommendations for improvements.

Research Report 112 Use of melter slag as aggregate in open-graded emulsion mixes

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

Melter slag is a major by-product of the steel manufacturing process, and its potential for use as an aggregate in open-graded emulsion mixes (OGEMs), is the topic of this report. Crushed melter slag was first tested in 1991 for use in constructing access roads within a steel mill complex in New Zealand. Its performance was later trialled on a state highway intersection for about 4 years (1994–1997). The report details the results of the monitoring and evaluates its use as aggregate. Keywords: aggregate, bitumen, emulsion, melter slag, New Zealand, OGEM, overlay, pavement, roads, trials

Research Report 181 Riprap protection of bridge abutments

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

Criteria for selecting riprap to protect bridge abutments against scour were investigated. Experiments were conducted with a spill-through abutment under both clear-water and live bed conditions in a laboratory flume. The riprap size and apron size and extent were varied. The data were compiled graphically, with dimensionless variables representing riprap size and apron extent on the axes. A useful relationship was found, with a clear zone of partial failure. Keywords: bridge scour, riprap, protection, hydraulic modelling, abutment, live bed, mobile bed, riprap apron

Research Report 244 Road surfaces & loss of skid resistance caused by frost and thin ice in New Zealand

Published: | Category: Safety, security and public health , Research programme , Research & reports | Audience: General

The effects of frost and ice on the skid resistance of a range of road surface types used in New Zealand were examined in a laboratory-based study, carried out in 2001-02. Frost and ice were formed on samples in controlled climate test rooms. In addition the same range of road samples was exposed to natural frost. Road surface types tested included dense and open-graded asphalts, and both fine and coarse textured chipseals. Comparisons were made with actual roads in frost conditions. Fine textured road surfaces were found to be very vulnerable to loss of skid resistance in frost and ice conditions. Coarse textured surfaces appeared to retain more of their skid resistance in frost and ice although the increase in skid resistance is small. The implications for road management are examined.

Research Report 245 Assessment of rural road simulation modelling tools

Published: | Category: Integrated land use and transport systems , Research programme , Research & reports | Audience: General

This research investigated the relative merits of various simulation packages (in particular TRARR, TWOPAS and PARAMICS) for modelling vehicle interactions on rural highways. It assessed their suitability for use as tools for evaluating crash risk and travel efficiency, particularly in the prediction of vehicle speeds and bunching in typical highway situations.  All were found to have some strengths over the others for particular project applications. A review was also made of recent or developing models of rural crash risks (including IHSDM) and their potential application in New Zealand considered. Although the underlying methodologies appear promising, most would requre further adaptation for the New Zealand environment.
