Most Extensive Research Program on NPA Tough-Cells in World Validates its Performance

The following is partial list of the moving wheel tests, static and dynamic loading tests, numerical analyses and field trials conducted at the University of Kansas, under Professor Dr. Jie Han, et al since 2006. These studies investigated and demonstrated how Neoloy-based Tough-Cells and their 'beam-effect' increase layer stiffness, soil bearing capacity, distribute vertical stresses, reduce permanent deformation, and extend road life compared to unreinforced and HDPE Soft-Cells road bases.
