Análisis comparativo de costo - beneficio entre pavimentos de hormigón con fibras de acero y asfalto en frío aplicado sobre empedrados, mediante simulación en el software Kenlayer

Abstract

This work develops a comparative cost-benefit analysis between two types of pavements, rigid using concrete with steel fibers and flexible using cold-placed bituminous asphalt, applied on existing cobblestones.

The empirical method of AASHTO-93 was used for the design of the flexible pavement, and for the design of the rigid pavement the Portland Cement Association (PCA) method. To support the design, the “Geometric Design Standards of the MTOP” have been taken, which are those that govern Ecuador.

By means of the simulation that represents the structure of each pavement, in the KENLAYER computer package, a comparison of the deformation and stresses in each layer of the structure and damage range was made, by applying a load of 8.2 tons of a standard design axis, which represents the passage of daily traffic in the study area. For the cost analysis, a budget was made for each type of pavement for a kilometer of track length, using the unit price analysis for each item.
