Soil and Aggregate Compaction

CHAPTER 1: TEST DESCRIPTIONS SOIL AND Aggregate Compaction OVERVIEW OF TEST METHODS MARTCP ROUNDING PROCEDURE, MARTCP METHOD This method addresses rounding-off of numbers from test results and calculations. AASHTO T 99 THE MOISTURE-DENSITY RELATIONS OF SOILS USING A kg ( lb) RAMMER AND A 305 mm (12 inch) DROP This is a laboratory run test that determines the maximum theoretical dry density of soils utilizing a lb. hammer dropped at a height of 12 inches to compact layers of soil in a standard mold. The test is used to define the optimum level of soil or Aggregate that can be compacted into a unit volume with a level of compactive energy that is similar to that obtained by standard construction equipment. Fig T 99/T 180 Test Apparatus 1-1 AASHTO T 180 MOISTURE-DENSITY RELATIONS OF SOILS USING A kg (10 lb) RAMMER AND A 457 mm (18 inch) DROP This is a method of determining the maximum theoretical dry density of soils.
