Plastic is considered as the one of the biggest invention of the era. Being lightweight, non-toxic and easy to handle & transport found various applications in the todays world and widely used everywhere. With the heavy rise in the populations, the need of plastic also increases which consequently also leads to rise in the plastic waste. Plastic are derivative of hydrocarbon, HDPE being one of them, mainly are non-biodegradable therefore causes the problem to where to dump the waste. So the principle of recycling now playing a major role for tackling this situation. In this investigation, standard proctor test and in addition CBR test are performed to check how the fine-grained soil behaves with the addition of various proportions of HDPE strips along with the chemical gypsum. Experiments are done for various proportions and then compared with the parent soil. Positive results are shown with addition of gypsum and HDPE strips. There is a rise in the value of CBR with the increasing proportion of gypsum and in case of HDPE strips, the value rises till 0.75% thereafter the CBR value declines. From this examination it is determined that accumulation of HDPE strips and gypsum improves the strength of weak fine-grained soil and a cost-effective pavement can be made. Also, it reduces the problem of dumping plastics to some extent hence decreasing load on waste management.
