Abstract
Geogrid is used to develop a mechanically stabilized layer (MSL) in conjunction with the aggregate base below a flexible pavement, enhancing aggregate stiffness. The MSL improves pavement performance and reduces thickness requirements of conventional materials, lowering initial construction and life-cycle costs. This concept has been adopted by local agencies throughout Indiana. In this session we will discuss the quantification of geogrid benefits in terms of M-E and AASHTO 93 methodologies, field performance verification, and cost-benefit analysis.
