ABILITY OF CLAY FILL TO SUPPORT CONSTRUCTION PLANT PART 2
CONSIDERATION IS GIVEN TO THE SUITABILITY OF USING SHEAR STRENGTH AS A CRITERION IN THE VARIOUS PHASES OF EARTHWORK DESIGN AND CONSTRUCTION. WHERE A LARGE AMOUNT OF MATERIAL IS RELATIVELY WEAK AND THE COMPACTED SHEAR STRENGTH IS INADEQUATE TO SUPPORT EARTHMOVING EQUIPMENT, THE POSSIBILITY OF USING LOWER TYRE PRESSURE SHOULD BE STUDIED AND THE OPERATING COST OF DOING THIS SHOULD BE RELATED TO THE CROSS SECTION DESIGN REQUIREMENTS FOR A STABLE FILL. LABORATORY TESTS SHOULD BE USED TO DETERMINE THE MINIMUM SHEAR STRENGTH OF THE FILL SOIL AFTER COMPACTION AT THE NATURAL MOISTURE CONTENT. TO CONTROL COMPACTION PROCEDURES, MINIMUM SHEAR STRENGTH OR THE COMPACTION PROCEDURE SHOULD BE SPECIFIED. IN PRACTICE, THE PRESSURE OF THE COMPACTION WHEELS SHOULD BE AT LEAST AS GREAT AS THE PRESSURE OF THE WHEELS OF EARTH- MOVING EQUIPMENT. SOME REMARKS ON PLANT REQUIREMENTS CONCLUDE THE ARTICLE. /RRL/
