Abstract: The design of the flexible pavement layers to be laid over the sub grade soil so the estimation of subgrade strength and traffic volume to be carried. The design of the various layers of pavement are dependent on the sub grade soil strength over which they are going to be laid. Sub grade strength is expressed in the terms of CBR value. weaker sub grade causes high amount of failures on surface of Flexible Pavement like Pot holes, various types of cracks and rut depth which is supposed to reduce ride quality of vehicles
In this study, we are making the use of solid waste is used in the construction of pavements and reducing the waste for land fill and making utilization of raw material in the embankments of pavements and also making the soil improvement by stabilisation process. Therefore, the present study will focus on literature work related to the field of soil improvement and solid waste related problems. Here an attempt has been made to lime stabilisation of black cotton (BC) soil with various percentage i.e 0%, 2%, 4%, 6% of waste Plastic bottle strips and study the engineering properties of soils MDD, OMC, Compaction, including CBR at different percentages plastic strips Keywords : Flexible Pavement, Sub Grade, Stabilisation, BC Soil, Lime, Plastic Strips, CBR. 1. INTRODUCTION waste management is still a challenge in Worldwide which is brought about by urbanization, increase population and industrial growth. The methods of disposing of solid wastes are in landfill, recycling and incineration. However, landfill spaces are reducing, incineration process emits hazardous gases, and recycling seem to be expensive and laborious. The current sustainable approach is to reduce, recycle and reuse. where it does not address properly the total waste which pollutes the nature and environment. There are several products which are manufactured from plastic according to growth of usage of plastic products these plastic products classifies in to plastic as follow: 1. Polyethylene Terephthalate (PET), 2. High-Density Polyethylene (HDPE), 3. Polyvinyl Chloride (PVC), Š 2017, IRJET

4. Low-Density Polyethylene (LDPE), 5. Polypropylene (PP), 6. Polystyrene (PS), and 7. Others (like polyester, polyamides, and polycarbonate). various use of plastic are packaging, furniture, automotive, agriculture, sport, electrical and electronics goods, health and safety, building and construction, and consumer and household appliances which Increase the uasge plastic products which makes increase in plastic waste, It has became a challenge to waste management authorities. 1.1
SUBGRADE
The crust of a pavement, whether flexible or rigid, rests on a foundation of the soil on an embankment or cutting, normally known as subgrade. Subgrade can be defined as a compacted layer, generally constructed with the avalibility of local material near to the project, assumed to be 500 or 300 mm in thickness, just beneath the pavement crust, providing a suitable foundation for the pavement. The subgrade in embankment is compacted in two or more layers based on the stability of foundation, usually to a higher standard than the lower part of the embankment .The soil in subgrade is normally stressed to certain minimum level of stresses due to the traffic loads and the subgrade soil should be of good quality and appropriately compacted so as to utilize its full strength to withstand the stresses due to traffic loads. This leads to reduce of the overall pavement thickness. On the other hand the subgrade soil is characterized for its strength for the purpose of analysis and design of pavement. 1.3 SUBGRADE PERFORMANCE Subgrade performance mainly depends on three of the basic characteristics, which are described as follows: 1. Load bearing capacity: The load carried by the surface of the pavements which are supposed to transfer load to the lower subgrade foundation of the pavement 2. Moisture content: Moisture is supposed to affect subgrade properties such as load bearing capacity, shrinkage and swelling. It also influence the drainage, groundwater table elevation, rain water infiltration, Generally, excessively wet subgrades will deform excessively due to load. 3. Shrinkage and/or swelling: Some of the soils shrink or swell depending up on their moisture content. Due to high ISO 9001:2008 Certified Journal
