| Summary, etc. |
This study aimed to determine the effectiveness of utilizing waste rubber tires with<br/>high-density polyethylene binder as a biaxial geogrid reinforcement material for subgrade<br/>soil based on its California-Bearing ratio. Powdered waste rubber tires were mixed with a<br/>binding material, shredded High-Density Polyethylene (HDPE), using a ratio of 65%<br/>rubber to 35% HDPE, 60% rubber to 40% HDPE, and 55% rubber to 45% HDPE. The<br/>mixture was processed under a roll mill machine and pressed in a compression molder to<br/>produce 8 inches by 8 inches sheet with 2mm thickness. An equally spaced 33-mm by 33-<br/>mm aperture was extruded from the sheet to form a grid. It was then tested for physical<br/>properties to determine rib thickness and aperture. Moreover, mechanical tests including<br/>tensile strength tested using a Multi-rib Tensile Method (ASTM 6637) and the California<br/>Bearing Ratio Test (ASTM D1883) performed on both commercially available geogrids<br/>and the waste rubber geogrid. Test specimens include unreinforced subgrade soil, a<br/>subgrade soil reinforced with commercially available geogrid, and a subgrade soil<br/>reinforced with the rubber geogrid. The results showed that among the variants of waste<br/>rubber tire geogrid that was made, the ratio of 65% rubber to 35% HDPE was the most<br/>viable mixture due to having the closest CBR value when compared to the commercially<br/>available geogrid. The researchers also concluded that the other mixtures of WRT geogrid<br/>were still competent enough due to having positive change/improvements. Therefore, it<br/>concludes that all design mix ratios have an effect in increasing the CBR value of<br/>unreinforced soil but only design mix ratio 60:40, 65:35, and commercially available<br/>geogrid shows a notable effect as supported by their strong significant difference. |
