Crash barrier on reinforced earth wall: Liverpool Parramatta Transitway

Reinforced earth walls are increasing being utilised for economic and aesthetic reasons as earth retaining structures on and around road traffic installations. Reinforced earth walls are often a very competitive solution for earth retaining structures, but when crash barriers have to be placed on top of them, it is difficult to carry the crash load forces back into the reinforced earth. A solution was required by Abigroup Contractors to comply with the specified barrier impact loadings without overloading the reinforced earth wall, while at the same time minimising the barrier concrete foundation costs. This paper shows how an economical and effective solution was achieved using designs to isolate the crash barrier lateral impact loads from the reinforced earth retaining walls and the method of allowing for thermal and shrinkage effects along the long slip-formed concrete barriers.
