Precast L-type retaining walls installed on the road receives the wheel load of the passing vehicle with a product extension of 2m through the backfill because the products are not rigidly connected. In this study, firstly, lateral pressures acting on the wall through backfill was measured by repetitive loading experiments using the wall of a box made of light gauge steels. Secondly, pseudo L-type retaining walls were fabricated, and static destructive tests were performed on the stems. Based on the results obtained from static destructive tests and lateral pressures acting on the wall of light gauge steels, wheel loads at which pseudo-L-type retaining walls break under repetitive loading was estimated. Finally, repetitive loading tests were performed with wheel loads around the estimated failure load on pseudo L-type retaining wall. As a result, It was confirmed that the number of loads that the stem breaks through the backfill soil on the back of the pseudo L-type retaining wall changes depending on the magnitude of the repeated load.
