Avaliação da aderência de revestimentos asfálticos em locais de maior incidência de acidentes de trânsito na cidade de Campo Mourão - PR

Abstract

The combination of factors such as recklessness, weather conditions, lack of signage, road conservation, human and vehicular failures, are related to traffic accidents. Therefore, it is extremely important to maintain the quality of the pavements, not only in terms of irregularities and pathologies, but also in less apparent factors such as friction and a surface texture. These are responsible for ensuring a more gripping and safer surface, directly influencing the time of braking, acceleration and changes of direction of vehicles. This study aims to analyze the surface textures of the asphalt pavement in places with a high rate of traffic accidents in the city of Campo Mourão / PR. In order to verify if there is a correlation with the local tire¬pavement adhesion and the number of accidents. For this it is necessary to study a microtexture and macrotexture of the surface of the asphalt pavement, the compounds generally used for this purpose are the British Pendulum and Sand Spot, which are low cost and easy to handle. The study found that some chosen points had a macro texture to the recommended value, but for a more indepth assessment it would be necessary to jointly analyze the characteristics of the roads and other factors that are important for the occurrence of traffic accidents. It was also analyzed that as the value of macrotexture increased, there was a tendency to increase the number of traffic accidents.
