This technical memorandum provides advice on the recommended practice for the mitigation of hazards associated with tubular handrails commonly installed for pedestrian/cyclist protection adjacent to roadways and on structures. This includes older tubular rail barrier systems on bridges with or without an adjacent footpath.
This report identifies possible methods and constraints on the use of waste tyre rubber in asphalt in New Zealand. There are two main methods: Wet process - ground tyre rubber (GTR) is first combined with the asphalt binder and can produce asphalt with superior properties; and dry process – the GTR is used to replace a fraction of the aggregate and does not appear to offer any performance enhancement.
The launches of the Safer Journey’s initiative and the Decade of Action for Road Safety have brought the way we design for safety into focus. The purpose of this document is to define the Safe System philosophy for dual carriageway roads and how this may vary with context. In particular these guidelines are intended for use on all the roads of national significance (RoNS) projects.
