TECHNICAL FEASIBILITY STUDY OF THE IMPLANTATION OF A DRAINAGE SYSTEM WITH THE USE OF PERMEABLE ASPHALT, AS AN ALTERNATIVE FOR FLOOD MITIGATION, IN URBAN AREAS OF MANAUS

Abstract

With the significant expansion of urbanization by man, as well as the growth of impermeable surfaces in cities, large urban centers begin to suffer high flow peaks through surface runoff and, consequently, an increasing frequency of flooding, causing environmental, social and economic damages. In Manaus, it is enough to arrive the period of intense rains, that these problems are evident in several points of the city. In view of this, the need arises to seek solutions for the mitigation of the problem, through the use of alternative recoating materials, such as permeable asphalt. The aim of the study was to carry out a bibliographic survey to identify the technical feasibility of implantation of the permeable asphalt. The method used to carry out this research was the deductive method. The type of research adopted covered three aspects: the objectives were an exploratory research; approach to the problem was qualitative; regarding technical procedures, was bibliographical. After carrying out this study, it is noted that the placement of a layer of geotextile blanket will increase the duration of the asphalt, causing any residue or water that flows in the cracks or holes to reach the geotextile blanket, diverting to the sides of the tracks where they will be drained.
