Analysis of the environmental temperature according to the type of soil surface in the city of Manaus

Abstract

The pavement is a structure conditioned to numerous factors capable of altering its physical and chemical form, being able to contribute or not to its good performance. The traffic, the climate, the characteristics of the materials that make up the pavement and the maintenance processes used, are preponderant for the determination and dimensioning of surface layers that are increasingly resistant to the elements of the day-to-day. The asphalt mixtures are composed of petroleum residues and present with dark pigmentation, which contributes to the absorption of solar radiation, being able to be determined by the Albedo index. It is valid the understanding of the relation between surface temperature and ambient temperature, since Manaus is one of the cities of the country that suffers most solar incidence, because it is near the equator. For the above, in this study, it is intended to demonstrate through temperature surveys in five different types of paved surfaces: Concrete, Asphalt Sand Machined to the Hot, Asphalt Concrete Machined to the Hot. Unpaved: grass and soil area, with distinct locations, these measures 1.5m from the ground. Data were collected at three different times, namely at 8 am, 12 a.m. and 5 p.m.
