    Compaction of soil is commonly used in earthwork construction like soil sub grades for pavements, embankments/dams, backfills etc. The main purpose of compaction is to accomplish higher quality, lower compressibility, and lower penetrability of soil. Soils behave differently for the different combinations of unit weight and moisture content. While there can be positive impacts of compaction, compacted clayey soils can cause serious problems when they are in contact with water, e.g. soil swelling etc. Compaction control is the most economical way to avoid undesirable effects on the construction characteristics of soil and to get more quality of soil. Soil properties vary due to variation of soil parameters in the field. Therefore, it is exceptionally basic to examine the behavior of clay under changing parameters. This study is basically on placement conditions of plastic waste material (PWM) on varying percentages. This research work included the compaction of clayey soils and the performance of unconfined compression test of soil and California bearing ratio test. The laboratory testing on the sample of Narowal clay included particle size analysis, moisture content determination, specific gravity, Atterberg limits, compaction test, unconfined compression test and California bearing ratio test. All these tests were performed according to the applicable ASTM standards CBR value at 0% of PWM was 5 unconfined compressive strength was 202kpa after adding 0.5% PWM then CBR value was 6 and unconfined compressive strength was 300kpa, at 1% of PWM CBR value was 8 and unconfined compressive strength was 352kpa and after adding 1.5% PWM CBR value was more increased up to 10. So it’s also shows that addition of plastic waste material in clayey soil increases the value of CBR and unconfined compressive strength
