    Development of an undisturbed method to measure density of improved municipal solid waste using heavy tamping
    (Department of Civil Engineering, University of Moratuwa, 2016-12) Basnayake, ABMRS; Nawagamuwa, UP; Hettiarachchi, MTP
    The core-cutter method can disturb a sensitive municipal solid waste (MSW) sample when measuring dry density of the soil. A mechanism has been developed to reduce this disturbance significantly, thus trying to obtain an accurate value for the dry density. The “resistance to the penetration” parameter of the soil was used as the theoretical background to develop graphical solution. An instrument was developed to measure penetration per blow value and it was calibrated with actual dry densities using Proctor compaction test. This mechanism was used to measure the compaction effect of heavy dynamic compaction, used in a predetermined grid pattern on a prepared MSW sample.
