Soil Modification with Shredded Rubber Tires
In California, rubber tires pose a major fire hazard and therefore, there is an increasing demand for the safe disposal or use of waste rubber tires. The geotechnical community has been trying to incorporate shredded rubber tires in various applications such as in the pavements of roadways and highways, the backfill of retaining walls, etc. Thus, the study of the compaction characteristics of soils modified with shredded rubber tires is essential to geotechnical engineering. Commercially available shredded rubber tires coarser than 2.75 mm were obtained from Home Depot. Different types of soils were mixed with these shredded rubber tires in three different proportions-10%, 20%, and 30% of the soil mass by weight. In this research, the testing was conducted on the following soil types: SP, SW, SM, SC, SP-SM, and CH, based on the USCS system. Each of the soil-tire mixtures were then tested using the Modified Proctor Compaction Test strictly following the procedure outlined by ASTM D 1557. Based on the results, the percent of shredded rubber tires required to in order obtain a reasonably good maximum dry density at a lower moisture content was determined for each of the soil types tested. The use of shredded rubber tires, therefore, reduces the amount of water required for the compaction effort, while maintaining a reasonably good maximum dry density as well as providing a solution for the disposal of used rubber tires.
