Abstract
Highways are of essential importance, since they are the main mode of transportation in the country, with a vast territorial extension of roads. However, many of these highways present some kind of alteration in their initial shape. The concept of paving, pathologies and their causes, as well as their recovery, are thus constituted. These problems were visually evaluated according to the Asphalt Pavement Restoration Manual of the DNIT (National Department of Transportation Infrastructure) in accordance with the TER 005/2003 and PRO 009/2003 standards, in a different area of the city of Manaus, namely the South Zone, consisting of the roads of the Industrial Complex, which allows the transportation of containerized cargo to the ports. The results, based on the visual surveys carried out and the current serviceability values, indicated roads with a concept between bad and regular.
Highlights
Today, the growth rate of the commercial vehicle fleet is increasing considerably, much more than was predicted when most of our highways were designed and built, and the effect of this is early deterioration of sidewalks with a wide variety of pathologies
The procedure was done by walking along the stretch of road, where the pathologies were visualized according to those exemplified by the classification, and photographic and written records were made describing such pathology (Figure 1)
The other pathologies in this group had a small sample, when compared to the above-mentioned, they have their degree of criticality, when analyzing the effect of aging, temperature variation, execution, water action, among other factors that affect the good behavior of the sidewalk throughout its service life
Summary
The growth rate of the commercial vehicle fleet is increasing considerably, much more than was predicted when most of our highways were designed and built, and the effect of this is early deterioration of sidewalks with a wide variety of pathologies. This is the main reason that worries those responsible for the maintenance of these roads. The main function of the sidewalk is to allow safe and satisfactory traffic throughout its life cycle The main function of the sidewalk is to allow safe and satisfactory traffic throughout its life cycle (BRITO, 2007, p. 34)
