Abstract

Transport plays an important role in the development of any country. Transportation has several modes of transportation such as road, rail, air and water etc. Among the following modes of transportation, road network is one of the important modes of transportation, it is used by every person in their daily life. Road network construction plays an important role in the development of any country. Roadways consist of several layers, these layers follow each other as base, subgrade, base and surface layer. The base layer is considered one of the most important layers. The construction of any engineering structure on weak subsoil or soil is considered dangerous to human life. Weak soil cannot withstand the high stresses coming from the structure. Therefore, stabilization of the subsoil is necessary for the construction of the engineering structure. The subsoil in the transportation system plays a very important role in transferring the loads originating from the superstructure to the existing ground surface, so it should have the capacity to bear this load.In this experimental study, our aim of work is to stabilize or improve the soil properties of Karnal using rubber tire waste. Waste rubber tires are a type of solid waste and are produced in large quantities in India. This experimental study involves different steps. In the first step of this experimental study, to find out the properties of the soil, we conducted various tests on the soil, such as wet sieve analysis, Atterberg limits, specific gravity, standard Proctor test and California bearing test, after analyzing the results of various tests, we come to the conclusion that the Karnal Soil was a silty soil with low plasticity index and had a lower CBR value of almost 3.4%-3.5%, which is not suitable for a transportation system. In the second step of this experimental study, we mixed rubber tire waste with soil at different percentages according to soil dry weight to improve soil stability. Mixing was done manually. In the third step of this study, we will again perform the standard Proctor test and the California bearing test on soil mixtures with different percentages of waste rubber tires and find out the value of the different result obtained from these two tests. Using these CBR values obtained from the tests, we determine the pavement thickness and also perform a cost analysis of the flexible pavement at 2 msa, 5 msa and 10 msa operation.
