Innovative Surfacings: What's New in New Zealand

The paper discusses recent innovations, new technology and current projects that are specifically targeted at the next generation of pavements, for a wide range of areas covering environmental, developments in surfacing materials, maintenance and construction practices, data collection , and other related topic areas. Modern computer-controlled sprayers have been developed to apply bitumen at rates that vary transversely across the lane width and are being used when chipseal surfaces have insufficient macrotexture in the wheeltracks as well as a preventative measure for binder rise in the future. Ultra high-pressure watercutting has been adapted for use on road surfaces, to improve both macrotexture and microtexture of surfacings, to rejuvenate the surface to that of a near new surfacing. This paper presents results from initial research into these surfacing treatments as well as in-service performance results from up to 5 years monitoring of other innovative treatments discussed in the paper. In order to ensure the programme of treatments is always optimised, a holistic approach to solving skid and texture deficiencies on sealed roads has been developed, and this approach is described in the paper. The paper discusses the technical and environmental aspects of the treatments that make them sustainable, and the implications for the road authorities and contractors. The paper concludes with the author's vision of the next generation of cost effective, smarter pavements.
