Evaluation of Strength Characteristics on Black Cotton Soil–Stone Dust Mixtures Reinforced with Shredded Tyre Rubber

Disposal of waste materials is a big problem with exceptionally growing up country like India. Rapid industrialization, population explosion, an extensive repletion of natural resources produces large quantities of waste materials which cause serious geo-environmental problems. Expansive soil swells and shrinks with regular wetness variation make structures founded on it unhinged and in practical cause huge economic loss in transportation division. In this, find out the waste material stone dust as a stabilizer and shredded tyre rubber which acts as a reinforcing material is selected. In the present study, stone dust blend to black cotton soil in changeable percentages of 5, 10, 15 and 20% by dry weight and shredded tyre rubber in varying of 1, 2, 3 and 4% added to black cotton soil stabilized with optimum percentage of stone dust. The treated and untreated samples were subjected to compaction, CBR (soaked and unsoaked) and unconfined compressive strength tests. The experimental values proved that there is a significantly increase in strength parameters for the black cotton soil added with stone dust and shredded tyre rubber combination.
