Effect of Addition of Scrap Tire Chips in Stabilization of Clayey Sand
As existing highways are continuously upgraded by adding extra lanes to cater to the needs of developing counties, demand for suitable construction materials for highway embankments is increasing day by day. As it is desirable to make the construction with locally available soils to minimize construction cost, efforts are required to stabilize such soils if they are inferior for use as construction material. Also, clayey sand with excess fines (more than 30%) possesses low CBR values in soaked conditions. Hence, in the present study, locally available clayey sand is stabilized with scrap tire chips of size 10 and 20 mm size in varying proportions of 0–20% by weight. The optimum percentage of tire chips by weight for the stabilization of clayey sand is determined as 15%, with 10 mm size tire chips exhibiting a better stabilizing effect than 20 mm size tire chips. The permeability and soaked CBR of clay sand are increased by about 85% and 65% respectively. Clayey sand under study stabilized with 15% of 10 mm size scrap tire chips indicated the potential for use in the construction of high embankments. Furthermore, improved stiffness of stabilized soil with tire chips in terms of coefficient of elastic uniform compression is observed from small-scale cyclic load tests.
