Modelo para la evaluación de la durabilidad proyectada en mezclas asfálticas Tipo Md-19: aplicación puente Av Boyacá con calle 127, Bogotá D.C.

Abstract

The durability of asphalt mixtures is a determining factor in the preservation and functional performance of road infrastructure. In the urban context of Bogotá, variable climatic conditions, high traffic volume, and construction deficiencies lead to accelerated deterioration of flexible pavements, especially those made with hot-mix asphalt (MD-19). This work proposes the development of a predictive model for evaluating the projected durability of this mixture, integrating mechanical, physical, and environmental parameters that influence its service life. The model combines the characterization of properties such as roughness, slip resistance, and pavement macrotexture. Statistical tools and regression models will be applied to correlate the observed deterioration with performance variables, seeking to estimate the remaining service life of the pavement. The expected results will support decision-making for the maintenance and rehabilitation of the road network, optimizing the allocation of public resources and promoting predictive and sustainable management of urban pavements in Bogotá D.C.
