Resumen

In this document analytical equations for the prediction of the rigid pavement slab thickness according to the method of PCA (Portland Cement Association) are proposed. The research was performed using the statistical technique of experimental design, for which the input data was determined by an analysis of the equations, tables, graphs and nomograms proposed by the PCA. A computer program was implemented in MATLAB to analyze various parameters in an efficient manner, allowing the selection of viable solutions. The proposed models allow the analysis of the slab thickness in a simpler way without having to incur the subjectivity of using nomograms, figures and tables. The derived equations have a significant reliability expressed through the correlation coefficients that are higher than 0.9750. Analysis of the models revealed that the use or not use of concrete berms largely influences the slab thickness, while the use or not use of dowels have a smaller effect. Independent of the use of berms, in the case of using dowels, the proposed models were the simplest and the most influential variable was the concrete rupture modulus. If dowels are not used, the reaction module of the subgrade was the parameter with the highest incidence. Examination of the most relevant parameters enabled optimization of the slab thickness, and definition of the design with best cost-benefit.
