Evaluación superficial de algunas calles de la ciudad de Loja

Abstract

Preserving the existing highway patrimony in the City of Loja, for the Lojanos is of paramount importance and more than that, it is the responsibility of the engineers to provide methods that allow to fulfill this mission; It is in this way that the present investigation intends to show a method of quantification of the superficial deteriorations existing in some streets of the City of Loja; Being able to be applied to the majority of streets of the city, which will allow that it is possible to be implemented and to plan adequate policies of maintenance. Knowing the state of deterioration that has a track is a vital component in the system of maintenance of pavements, so that, through this can be achieved a future projection of the state of the pavement. There are a number of methods that allow for a future projection of the state of a pavement, some more precise than others, but all these agree that if you have a precise quantification of the current condition will get an accurate projection, Thus, after investigating several methodologies for the quantification of the current state of a pavement, it has been decided to apply the one that is standardized by means of ASTM D 6433, "Standart Practice for Roads and Parking Lots Pavement Condition Index Surveys" Or better known by its acronym PU (Present Condition Index). The Pavement Condition Index (PC¡), was developed between the years 1 974 to 1 976 by the United States Air Force Engineering Corps and executed by Engineers Messrs. Mohamed Y. Shahin, Michael L. Darter And Starr D. Kohn, in order to obtain a management system for the maintenance of rigid and flexible pavements through the PCI.
