Dr. Md Ashrafuzzaman Khan, Dr. Anand Puppala, Dr. Nripojyoti Biswas, and Dr. Surya S C Congress are thrilled to share their latest publication, “Evaluation of the Structural Performance of the Geocell-Stabilized Flexible Pavement.” This paper delves into the world of geotechnical engineering and road construction, offering new insights that could revolutionize the way we build and maintain our roads.
This study explores the use of geocells in pavement infrastructure, offering a sustainable solution by allowing the use of reclaimed and inferior-quality base aggregate materials. Despite the recognized benefits of geocells, their field performance in flexible pavement design is not well understood, which has limited their adoption by transportation agencies. The results showed that geocells enhanced the performance of RAP material and allowed for its maximum usage. The confinement provided by the geocell increased the in-situ modulus by 8 to 20 psi, indicating an increase in resilient modulus. Geocells also helped to limit the differential movement of the subgrade, providing uniform support and resulting in a smoother road structure with less rutting and longitudinal cracking. This study thus highlights the potential of geocells in improving pavement performance and sustainability.
We invite you to read our paper and join the conversation on sustainable and efficient road construction. Your thoughts, questions, and insights are most welcome!
