Are soil borings important to the design of a precast noise barrier?
Yes, soil properties are probably the single most important design aspect of a precast concrete noise barrier. Soil borings should be performed at least every 100 feet along the length of a noise barrier, especially when soil conditions are expected to vary. Borings should be taken along the proposed location of the noise barrier, not in the center of the proposed roadway or at bridge abutments located on the same project.
