~ Observed cracks in the facing were located at the expansion joints because the architectural finish coating was applied over the joints.
~ Some discussion on whether the concrete barrier rail protecting the retaining wall facing could be either integrated into the concrete facing or be elimninated. It was also noted that:
~~ Protecting areas where the facing begins and ends are of most concern.
~~ A vertical concrete barrier offers comparable protection to a slope-faced barrier.
~~ Integrating the barrier rail, vertical or sloped into the concrete facing is feasible.
~ Deck cracking:
~~ A correct pour sequence is very effective in mitigating deck cracking.
~~ Contractors should consider the viscosity of gravity flow crack repair products.
