Evaluación de la estructura del pavimento en el tramo del malecón de Puerto Bolívar

Abstract

Road infrastructure is said to be of great importance, as it facilitates the quality of life of the population, because it is a fundamental and essential tool for the social and sustainable development of a population that seeks to expand through trade. Over the years, roads have evolved and have had a crucial impact on society, since it can be emphasized that roads have been built with the purpose of connecting places, with the objective of exchanging goods, products and food between neighboring places. Likewise, it can be mentioned that currently the roads in our country do not have the adequate road system. For this reason, it has been determined to carry out the structural study of the road section of the Puerto Bolívar boardwalk, in order to know the current state of the road and thus generate a thickness proposal in accordance with the established regulations, generating an adequate study of the pavement structure. The Puerto Bolívar boardwalk road has an extension of 0.95 kilometers in length. It should be mentioned that this road has an asphalt pavement as a tread layer. In addition, it is considered that the study carried out on the subgrade at a depth of 1.50 m obtained a CBR of 6.01%, which is why it was determined that according to the AASSHTO 93 standard it is classified as a POOR subgrade. On the other hand, the granular bases of the samples extracted at a depth of 0.5 m and 1 m were analyzed. They present inconsistencies in these layers, since its soil is SAND (SP), which means poorly graded sand, where the lack of compaction and cohesion of this material affected the capacity of the soil to support existing loads. In addition, the determination of the structural package is 80 cm, and there is also a sub-base of 60 cm, that is, it is indicated to propose 30 cm of improvement and 20 cm of class II sub-base in order to reduce the costs for our design.
