Design approach for geocell reinforced flexible pavements

Geocell is a comparatively new reinforcing material in civil industry. The unique three dimensional confinement of this material separates it from other geosynthetic reinforcing material, such as woven geotextile, geogrids, etc. The local soil or granular material show better structural properties when confined in geocell with a proper manner. The incorporation of geocell in pavement layers facilitates a better load distribution and reduction in vertical stresses underneath the pavement structure. Hence a significant thickness reduction is possible by using this cellular confinement technology in flexible pavements. There has been a lot of literature published to incorporate the reinforcing effect of geotextile and geogrids in paved and unpaved pavements. However, for geocell the design implication is still in infancy and has not been standardized yet. This paper is intended to provide a mechanistic empirical design guideline for a geocell reinforced flexible pavement with its positive outcomes, as well as limitations. The design is aimed at following the basic rules of the Indian Roads Congress (IRC) guidelines.
