Evaluation of the Optimum Mixing Ratio of a Sand-Tire Chips Mixture for Geoengineering Applications
TLDR
In this paper, the optimum mixing ratio of sand-tire chips (STC) mixtures based on void ratio and shear strength properties was evaluated and the results showed that the addition of tire chips up to 40% by weight showed significant decrease of void ratio by 43%.Abstract:
This paper presents the evaluation of the optimum mixing ratio of sand-tire chips (STC) mixtures based on void ratio and shear-strength properties. Locally available sand and tire chips of 20×10 mm size are adopted. Different STC mixtures, in the range 10–70% by weight of tire chips (TC), are considered, along with pure sand (0% TC) and pure tire chips (100% TC). Specific gravity, density, and large direct shear tests were conducted for various samples. The volume of voids and weight-volume relations were determined from the dry unit weight and specific gravity values obtained for various mixtures. The results showed that the addition of tire chips up to 40% by weight showed significant decrease of void ratio by 43%. Shear-strength properties, like angle of internal friction values, are increased with TC contents up to 30%. Based on experimental results, the optimum percentage of tire chips of the selected size is in the range of 30–40% by weight, which is the equivalent of 50–60% by volume. Furt...read more
