Shotcrete design guideline : design guideline to improve the appearance of shotcrete in NSW / Urban Design Roads and Waterways ; Transport for NSW

"This was the third guideline published under the Beyond the Pavement initiative and addresses the issue of the visual impact of shotcrete. While shotcrete is a useful and cost effective means of stabilising or supporting cuttings if not designed well it can be particularly unsightly. It can obscure the underlying natural geology and prevent revegetation, both aspects of a road journey that customers find interesting and comforting. In terms of maintenance and long term stabilisation it would be better if the need for its use could be avoided by securing enough land to lay back cuttings to a stable gradient. This document recommends the best way to avoid the need for shotcrete is to consider the ramifications of the vertical and horizontal alignment very early on in the route selection and concept design stages. However this is a practical document and it is recognised that in certain situations there are sound reasons for shotcrete use. For these cases a number of measures are provided to minimise its extent and improve its appearance all with the aim to make the application as unobtrusive as possible." -- Page 2.
