Pavimento das rodovias federais interioranas - estudo de caso: trecho da BR 226 - Pereiro - CE

Abstract

The most used mode of transportation in Brazil is the road, where, according to Lizot (2016), 76% of the goods are transported by trucks or trucks. The E - Commerce News (2017) complements that when the transportation is done on a bad highway, the value of the freight grows around 25% and when it is done on a road in very poor condition, this increase can reach up to 92%. With the economic crisis that the country is going through, cuts have been made in all sectors, including in the construction, maintenance and maintenance of highways, which contributed to the worsening of the state of Brazilian highways. The present work analyzes the current situation of a section of BR 226 connecting the municipality of Pereiro - CE to BR 116, with the objective of characterizing the study, identifying the existing pathologies and the condition or existence of essential elements traffic safety. In order to do so, a volumetric and traffic volume counting survey was carried out, a bibliographic review of the pertinent themes for the evaluation and recovery of highways and a photographic record of the defects found in the section that marked the subjective evaluation of the pavement. Finally, based on the results obtained, suggestions were made to remedy the problems encountered and to improve pavement conditions. By going through the section under study it can be verified that it has holes along its entire length, allowing water to seep into the pavement structure, degrading it. It was also verified the occurrence of localized sinking. These pathologies, besides causing discomfort to the user, favor the occurrence of accidents, even with fatal victims. Another serious problem was the obstruction of the drainage elements present in the stretch. Gutters are obstructed by garbage or other vegetation, diverting rainwater to the surface of the pavement, thus increasing the risk of slippage and aquaplaning. Therefore, it is possible to conclude that the highway in question needs recovery / restoration as quickly as possible to prevent problems from evolving and causing more misfortune to the public who use it, as well as greater expenses in the execution of pavement restoration services.
