10+ Years of Experience in Concrete Slabs with Optimized Geometry

In 2005, a new concept in concrete pavements was developed, Concrete Slabs with Optimized Geometry. This technology is based on designing the concrete slabs so that no more than one wheel or set of wheels will be loading the same slab at any time. This causes the slabs to work in a different way than usual, decreasing stresses and allowing a reduction in thickness, when compared to a traditional concrete pavement design. All without reducing its lifespan and increasing its fatigue resistance. Since 2005 there have been important developments of this technology. With more than 129 million square feet (12 million square meters) in application, 200 projects across 10 countries, the technology has been used in many different climates and loading conditions. All this information has helped to calibrate and understand the behavior of this new system. This paper shows the most important things we have learned in the last 10+ years, also explanation of the development and protection for the technology.
