Popis: The main purpose of soils compaction ratio computing is to check the compaction ratio of soil fill with respect to maximum soil dry unit weight.This study produces compacting soil ratio calculation based on reading of the soil pocket penetrometer. The pocket value within certain procedure contains testing the same point location selected to test soil layer that adopted in standard normal compaction ratio determination. The four to five points pocket penetrometer tool tested at the compacted topsoil layer surface. The results of (130) points indicated that there is a good agreement between compaction ratio and pocket penetrometer readings with the linear interpolating relationship. The study also predicts linear relationships design equations for predicting compaction ratio and modulus of sub-grade reaction with acceptable regression (R2) values but with certain limitations.
