A comprehensive analysis of geotextile reinforcement in pavement design

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. 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.
