Abstract:

Ramps leading, for example, to overpasses or bridges are usually constructed using

mechanically stabilized earth (MSE) walls, earthworks retained by concrete walls. Because

MSE walls are reinforced with steel embedded in the fill, their fill is carefully chosen for its

electrical and chemical properties, to minimize corrosion. Voids that form in MSE walls due to

settling are repaired with controlled low-strength

material (CLSM), mostly made of cement, which

is highly alkaline and can affect the pH of the

fill, leading to more corrosion and accelerated

deterioration of MSE wall reinforcement.
