The use
of
shotcrete has recently come under scrutiny. Although it is cost
effective and useful, when used in its natural, untreated state, it is
visually intrusive, particularly in highly sensitive urban or rural
areas. Due to its poor visual qualities there is often a call to
restrict its use. However, this is not possible as it is a valuable
engineering technique, useful for stabilising and providing structural
support for problematic slopes. This has unnecessarily caused a
difference of opinion within road design teams because if considered at
the outset, in the route selection and concept design stages, designers
and engineers can agree on a common goal to avoid the need for slope
stabilisation for visual as well as cost and maintenance reasons.
Therefore this document addresses the need to consider unstable slopes
early on in the road development process and sets down a strategy and
recommendations to avoid or minimise the eventual need for shotcrete.
However it also recognises that there will be circumstances where
shotcrete is inevitably required and addresses the real practical
problem of what is an acceptable appearance
