Design of Flexible Pavement by Group Index method

The design of flexible pavements plays a crucial role in ensuring the longevity, safety, and cost-effectiveness of transportation infrastructure.Among the various methodologies available for pavement design, the Group Index method stands out as a widely used approach due to its simplicity and practicality.This research aims to provide a comprehensive analysis of the design process of flexible pavements utilizing the Group Index method.This study explores the use of the Group Index (GI) method for determining flexible pavement thickness.The GI method considers soil properties, traffic loading, and environmental factors to estimate pavement structural adequacy.Modern technologies like GIS and pavement performance models enhance the accuracy of this approach.Case studies or simulations illustrate the method's effectiveness in optimizing pavement thickness.The findings contribute to pavement engineering by offering a reliable method for designing flexible pavements suited to local conditions.Adoption of the GI method supports the construction of resilient transportation infrastructure, promoting socioeconomic development and safer mobility.
