Based on the results of the tests, we recommend that the concrete street subgrade be
stabilized with the addition of 6 percent hydrated lime (28 pounds per square yard for a
six -inch stabilized layer). The lime and the stabilization and compaction of the subgrade
should be performed in accordance with the applicable City specifications.
