    WK46655

    1. Rationale

    Incorporation of the Uniform Soil Groups for Pipe Installation for each bedding class of vitrified clay pipe for use as both bedding material and initial backfill. Referencing the Uniform Soils Groups as modified for pipe installation brings this standard in conformity with normal industry practices. Also, corrects reference to CLSM compressive test method; adds text reference to figure 1 in terminology section; clarification on foundation improvement, compacted bedding, initial shovel slicing of the pipe haunch, and backfilling. Removed reference to puddling which was determined to be infrequently used terminology.
