Abstract

In 2005, Chile introduced the technology for designing concrete pavements with optimized geometry slabs. This technology is based on reducing the size of the slabs so that there is at most one set of truck wheels loading a slab simultaneously. This reduction decreases the internal stresses within the slab, allowing for a reduction in slab thickness without affecting its lifespan or increasing its durability without changing the thickness.
This article presents an objective analysis of the performance of this pavement design technology in projects tendered by the Dirección de Vialidad of the Ministerio de Obras Públicas, totaling 262 km-lane of constructed road. Field measurements, such as the International Roughness Index (IRI) and Cracking, are compared with data generated or predicted by the design model, thus allowing for an evaluation of its performance over time. The results show compliance with the predictions in terms of the International Roughness Index and cracking, except for one cracking measurement that exceeded expectations. These measurements are also compared with those of a traditional concrete pavement contract as a control parameter, showing a favorable difference for the optimized geometry slab concrete pavement technology concerning cracking and the International Roughness Index.
