Plan de mantenimiento para la estructura de pavimento flexible de la avenida Catama (Calle 35) en el tramo entre la carrera 20d hasta la carrera 5, Villavicencio

Abstract

Catama Avenue is a very important road corridor in the city of Villavicencio, where the pavement structure has been deteriorating, affecting the users who travel on the road. For this reason, it was necessary to carry out a detailed survey of the pavement pathologies and propose a maintenance plan for the pavement structure, specifically on 35th Street in the municipality of Villavicencio - Meta, in the area from 20d to 5, taking into account the most affected areas.

A vehicle count, taking into account the peak hours and analyzing the TPD (average daily traffic) was one of the first steps to evidence the percentage of heavy vehicles that travel on the road causing possible damage to the pavement. Subsequently, two methods were used to record and analyze the damage, the first being a visual inspection of the section, The second method calculates the PCI (Pavement Condition Index) to detail more precisely the damage to the pavement, taking into account the selected sampling units and thus identify the degree of impairment for each type of damage, density and level of severity on the condition of the pavement.

With the identification of the problem, data and sample collection, a maintenance plan is proposed that is based on the possible causes of the damage presented and on alternative maintenance that can be applied based on existing specifications, taking into account improving the structural capacity of the road and reducing maintenance and construction costs.
