SUBSURFACE INVESTIGATION, SECTION A014 ROCKVILLE ROUTE
Results are summarized of 58 test borings made at selected locations along the line of Section A014 of Rockville Route, generally following Rockville Pike north of Strathmore Avenue to Station 764+40 of the Washington Metropolitan Area METRO system where the METRO adjoins the B and O Railroad right-of-way. Five of these test borings were made with a large-size hollow-stem auger to assess the difficulty of excavation in the subsurface materials. The report includes a continuous geological section along the centerline of the METRO structures, special cross-sections at the location of the subway station and parking lots, logs of the test borings, results of laboratory tests on soil samples and comments on potential design and construction problems.
