                    • Request for information on prevalence coal tar

                      WasteMINZ is looking at developing a guide around management and disposal of coal tar in the road corridor. The guide is intended to provide direction on identifying coal tar embedded in asphalt or sub-base materials within the road corridor, options for managing it and disposal. From the work AT has done in Auckland (and presented at the RCA Forum a couple of years ago), we know that AT rarely finds coal tar during road corridor works.  We also know that Christchurch does identify coal tar more frequently as a result of the earthquakes, and management/disposal of the material is a concern.


                      What we don’t know is the prevalence of coal tar in the road corridor across NZ and whether other RCA members have an issue with it – either as an asphaltic material or in sub-base layers. The working group is keen to understand the prevalence and whether the proposed guide is likely to be useful to NZ RCAs.

                      Waka Kotahi has published an updated version of the Standard Safety Intervention toolkit.  This toolkit provides guidance for road safety practitioners on the effectiveness and value-for-money cost range of proven safety interventions to reduce the number of people killed and seriously injured on Aotearoa roads.




                    RCA Forums enable members to exchange information and provide updates on sector working group activities, proposed legislation, new standards and guidelines, highway and procurement strategies and other issues relevant to road controlling authorities and the other member organisations. A full index of forum resources is here.

                    Working Groups

                    The RCA Forum establishes specialised working groups to resolve issues that require a coordinated approach from the sector. These working groups continue as long as the issues require attention. The full list of resources for each working group includes references, past research, and coroner’s recommendations.
