Abstract: For pavement structure, geotextiles have been heavily suggested. However, there aren't enough fully-scaled, instrumented studies to look into how geotextile reinforcement affects pavement design. In this investigation, eight lanes of pavement test sections underwent full-scale expedited tests. Based on significant advancements in the studies regarding dry compaction on a sand base, design parameters, structure combination of subgrade and pavement, stabilization analysis of sand base strengthened with geotextile, and an entire set of construction techniques, several key technical issues in the construction of the Desert Highway have been satisfactorily solved. Over the past thirty years, it has become common practice to stabilize weak subgrades on minor roads using geotextiles. 2 designs to measure the benefits of employing geotextiles in pavements, many techniques were explored. To evaluate the advantages of employing geotextile in secondary road flexible pavement, however, it is urgently necessary to conduct a thorough life cycle cost analysis (LCCA), which takes into account both expenses to agencies and costs to users. To measure the benefits of employing geotextiles in pavements, two design methodologies were applied.In this study, a thorough life cycle cost analysis framework was created and utilized to calculate the current and future costs of 25 sample low-volume road design choices. The subgrade must be firm, stable, well-drained, and devoid of volume variations brought on by changes in moisture. If not, the pavement will eventually fail. Normally, there are ways to measure the benefits of utilizing geotextiles in pavements. However, from an economic standpoint, a pavement's entire life cycle shows that it fails for causes including structural, functional, or material failure, or a combination of these. However, it is noted that the pavement breakdown in the research region falls into the category of structural failure.
