Modulus Improvement Factor-Based Design Coefficients for Geogrid- and Geocell-Reinforced Bases

Mathematical Modeling of a Corrugated Geogrid and Geocell Reinforced Flexible Pavement Base with Interlayer Shear Performance Analysis

“…Saride et al [28], used monotonic loading tests to determine the installation depth of geogrid-and geocell-reinforced base courses for flexible pavements. The Modulus Improvement Factor (MIF), which ranges for both geogrid and geocell-reinforced bases, was used in this research to quantify structural support.…”

“…Overall from this literature study, it is understood that [16] did not consider the axial loading effect on the bonding between the geogrid and pavement layer, [17] the long-term performance also needs to be evaluated for the proper analysis, [18] a field monitoring of a railway section reinforced with geosynthetics is needed, [19] the properties of the filling material in the geocell need to be further studied, [20] the development of standardized testing methods is necessary, [21] the load transfer mechanisms between the geosynthetic and pavement layers also need to be studied, [22] the vehicle speed increases and the reinforcing effect reduces in asphalt layer, [23] instability in any of the layers will cause the paving system to fail, and in [25] the effect of encasement is directly affected by the stiffness of the fabric and in [26] it is not possible to use it in actual calculations. In [27] the need to improve the system's longevity and dependability, [28] more testing in various scenarios was likely needed, [29] requirement for additional validation used more widely, [30] interference effect causes potential challenges in specific situations, requiring further research, [31] necessary to validate geocell reinforcement's wider efficacy. Therefore, there is a need for a novel flexible pavement design using geosynthetic material with proper mathematical analysis to eliminate these limitations.…”
