Abstract: The preparation of the undisturbed peat sample at the site must be conducted to understand its characteristics. However, the sampling process becoming difficult due to the condition of peat soils itself. Due to the limitation in gaining undisturbed sample, a study on reconstitution sample becoming more popular in term of investigating the properties of soil that represent the real site condition. The main purpose of this paper was to investigate the physical properties of undisturbed and reconstituted peat RS3.350, RS2.360, RS1.000 and RS0.425. In this study, the segregation of peat and expulsion water with the aids pre-consolidation pressure was applied to the reconstituted sample. The range value of the physical properties of reconstituted peat was varied from each type of peat classification which affected by the segregation fiber and pre-consolidation pressure effect method. The entire reconstituted peat samples were recons passing the opening sieve size 3.350mm, 2.360mm, 1.000mm and 0.425 mm and were subjected with the 50 kPa, 80 kPa and 100 kPa pre-consolidation pressures. As a result, the natural Parit Nipah peat soil was classified as hemic peat (H5). The percentage of water content, liquid limit, organic content and fiber content for the reconstituted sample is lower compared to the undisturbed peat sample; but differed from specific gravity where the percentage for the reconstituted sample was higher than the undisturbed sample. Conclusively, the segregation of peat fiber and pre-consolidation pressure methods greatly affect and change the physical properties of peat samples.
