Density Based Experimental Analysis of Geosynthetic Materials in Application of Road Construction

Haroon Latief Khan

Abstract: This study was primarily concerned with the use of geotextiles, a geosynthetic membrane to strengthen the foundation of a flexible pavement. Three soil samples were collected from FUTA environs and all of the samples underwent primary soil tests such as natural moisture content, sieve analysis, compaction and California bearing ratio (CBR) test to determine the geotechnical properties of the samples. The relative advantages of placing different reinforcing materials like geotextile, biaxial or uniaxial geogrid, geocell layer and tire shreds at the interface of subgrade and base course are studied in terms of increase in load carrying capacity and reduction in rut depth. The rut depths measured in three different test sections when subjected to moving vehicle load simulated by the passage of a scooter on the road at uniform speed for a maximum of 250 passes are compared to understand the relative efficiency of each of these reinforcing materials in reducing the rut formation in unpaved roads. Traffic benefit ratios were also compared for different reinforced test sections.
