Análisis Comparativo de las Metodologías Empleadas para Diseño de Pavimentos Asfálticos en Colombia y Australia

Abstract

This monograph focused on conducting a detailed investigation of the current flexible pavement design methodologies in Australia and Colombia, specifically the INVIAS " Manual de diseño de pavimentos flexibles para vías con medios y altos volúmenes de tránsito " and the "Guide to Pavement Technology Part 2:Pavement Structural Design" by AUSTROADS. The aim was to find divergences and convergences in both methodologies, in order to analyze possible areas of improvement and whose purpose is to contribute effectively to the optimization of the design of more sustainable and efficient flexible pavements in Colombia. A significant variation in vehicular configurations between the analyzed documents was evident, emphasizing the importance of considering these classifications in pavement design to influence pavement strength, lifespan, and traffic management. Ultimately, it was observed that both manuals lacked information on sustainability and sustainable materials. It was noted that the "Guide to Pavement Technology Part 2: Pavement Structural Design" from AUSTROADS includes an economic comparison, whereas the "Manual de diseño de pavimentos flexibles para vías con medios y altos volúmenes de tránsito" from INVIAS does not address this analysis. Both methodologies implement the mechanistic-empirical method, combining mechanistic design based on pavement response to loads through mathematical modeling with an empirical approach that relates responses to performance, relying on experimental results and professional knowledge. Each pavement deterioration is linked to a specific critical response, emphasizing the importance of understanding and addressing these responses for effective flexible pavement design.
