Research Objective
This proposed research aims to achieve three primary objectives: (1) develop a large-scale track wheel (LSTW) test with multiple non-destructive testing sensors to assess the performance of geosynthetic-reinforced pavement, (2) evaluate the benefits of using geosynthetics to reinforce the surface, base layer and/or stabilize weak subgrade soil in a flexible pavement application, and (3) suggest the design parameters for geosynthetic-reinforced pavement based on the testing results.
Potential Benefits
These studies will be used to develop, investigate, and refine the understanding of underlying the mechanical behavior and performance of the geosynthetic-reinforced pavement system. The end results of this research project will suggest a performance chart of geosynthetic-reinforced roadway pavement systems with the selected sets of soil conditions, aggregate types, and the types and locations of geosynthetics.
Brief Description of Research Project
This study will evaluate the mechanical performance of a geosynthetic-reinforced pavement system at different layers of the pavement by using a large-scale wheel track (LSTW) test installed with various innovative sensors such as fiber optic cables, ultrasonic sensors, LVDTs, pressure cells. Also, the numerical simulation will be conducted for a full-scale roadway pavement reinforced with geosynthetics at the different layers.
