Investigation of the Effect of Natural-Fiber Geogrids on the Bearing Ratio of the Subbase Layer of a Road
In this study, the suitability of developing and applying different types of geogrids to increase road-subbase bearing capacity was investigated. Textile products obtained from natural jute fibers were transformed into a geogrid and used in the road subbase. Studies have revealed that natural fibers, typically obtained from agricultural waste, can be spontaneously degraded via natural processes. Therefore, the jute textile geogrid surface was coated with bituminous materials. In addition, commercially available geogrid materials made using basalt fibers were included as a road-subbase reinforcement in the study for a comparative analyze. The study was performed on a subbase material used in the subbase of a road. The developed and commercial geogrids were classified into different sample groups and subjected to ground tests. In the first group, tests were conducted on the road subbase material without using a geogrid. Thus, the basic physical properties and the California bearing ratio (CBR) values were determined and used as a reference for the bearing strength parameters of the ground. The second group was tested using the basalt geogrid on the same subbase material. The third group was subjected to the same tests using an uncoated geogrid developed with natural jute fibers. Finally, the fourth group was exposed to the same tests after the surface of the jute-fiber geogrid was coated with bitumen. Thus, four sample groups, including a reference (control), were evaluated for comparison. Test results indicated that the bearing strength of geogrid samples with natural fibers increased by 39.7% and 48.5% compared to control samples for CBR values of 2.5 and 5 mm, respectively. In addition, the bearing capacity of bitumen-coated natural jute-fiber geogrid samples increased by 17.8% and 22.4% for CBR values of 2.5 and 5 mm, respectively. After analyzing the bearing capacity of basalt geogrid samples, increases of 6.68% and 5.05% were obtained for CBR values of 5 and 2.5 mm, respectively, compared with reference samples.
