Evaluación superficial del pavimento de la vía c22 desde la Avenida Panamericana norte hasta el sitio Santa Cruz en el cantón El Guabo.

Abstract

The present research work is framed in a problem linked to society, being an inadequate road service on the C22 road between Panamericana Norte and Santa Cruz. Considering that the pavement shows defects in the asphalt layer, the objective was to perform a superficial evaluation of the pavement using normative methodologies for the analysis of the asphalt pavement, to know its stability value, percentage of asphalt, granulometry and the PCI method to determine the state of the pavement and, depending on the result, to propose a rehabilitation or maintenance intervention. For the asphalt analysis, a sample was extracted to perform the corresponding tests, adding the visual inspection, which was the technique used to complement the evaluation, investing two days of data collection to improve the consistency and quality of the result. As results obtained we can indicate that the average percentage of Marshall's stability was 850 lbf, the average percentage of asphalt was 4.06% and it also has an average PCI of 35, based on this and according to the ASTM D6433 Standard, it is considered as BAD in the study section. Having analyzed the data on the condition of the road, it was determined that milling would be the ideal alternative for rehabilitation treatment. Before milling is carried out, it is established that a technical estimate should be made of the condition of the road.
