Influência da qualidade do revestimento asfáltico na emissão de poluentes de um veículos leve em Fortaleza

Abstract

In view of the debate on air pollutant emissions and their effects on human health and the environment, this paper evaluates the relationship between the asphalt quality coating in urban centers and their influence on CO2 and NO2 emitions in the environment. air from the city of Fortaleza, Ceara. It was used a methodology that compared International Roughness Index (IRI) data and pollutant emissions emitted by incomplete fuel combustion in passenger car exhaust. In addition, a Continuous Visual Survey (LVC) was performed, the results of which were used to classify the roads studied for the degree of pavement deterioration. It is noteworthy the use of High Definition (HD) camcorder for filming the roads. Also a smartphone was applied to survey the stretches studied by calculating the IRI. The routes were chosen according to their potential for generating and attracting trips. Emissions were collected as close as possible to the pollutant source. With the obtained results, it is not discarded the relationship between asphalt quality coating and its direct influence on air emissions. However, the proposed method of calculation was validated in regards to the degree of deterioration the roadway lining have similar characteristics, such as wear, patches and cracks. The studied roads were: Vicente Linhares Street, Tibúrcio Cavalcante Street, Érico Mota Street, 13 de Maio Avenue, Jovita Feitosa Avenue and Senador Virgílio Távora Avenue.
