Abstract
The capabilities of geographical system and their spatial analysis is considered the most appropriate tools to enhance pavement management operations, with features such as graphical display of pavement condition. In Iraq, most of transportation agencies do not have a tool that is used as a database for road deteriorations, so there is a need for road surveying and storing the collected information in GIS to know the condition of every road with details. Furthermore, these data can be used for maintenance process and estimation of prior cost. This research has been carried out to estimate of flexible pavement condition through visual surveys using the Pavement Condition Index (PCI) method; so it can provide an easy way to calculate the PCI based on GIS data with Micro PAVER software 5.2. Al-Amarah Street, which is internal road in Al-Kut city in the eastern part of Iraq, is used as a case study. The average pavement condition index of the selected case study is found to be “64” using Micro PAVER 5.2 software which mean “Fair” pavement condition. Arc Map 9.3 has been applied in this study to make an integrated maintenance system for each road in the region demonstrating the annual road deteriorations and the resulting change in the PCI values which occurs every year. The study provides an easy and simplified way of presentation the details of deteriorations on the satellite or the geographical map of the road in which each type of distress has been symbolized with specific sign and each PCI value has been represented with specific color.
Highlights
Objective of the researchThe aim of this research is to produce a thematic map for distress types in the city network with their completely information about severity, quantity, (x,y) coordinates for each distress type
The functions of highway facilities are to provide travel quickly, safely, and comfortably
Geographic Information System (GIS) based system was built, which provides information that can be used as a platform for all aspects of the Pavement Maintenance and Management System (PMMS) process. 23 sections were selected that distressed with PSI element to draw a map that connected between roadway and their values of PSI
Summary
The aim of this research is to produce a thematic map for distress types in the city network with their completely information about severity, quantity, (x,y) coordinates for each distress type. Taking advantage of the ability of GIS tools to store the data and display it in any time needed; it is useful to use GIS as a database to make a decision for maintenance and to achieve best results at lowest possible costs. Visual surveys are used to determine the Pavement Condition Index (PCI) of the selected roads according to ASTM D6433-07, 2016 [1]. Many road institutions in Iraq suffer from lack in road documentation and do not have a database program for storing; this reflects a poor system of maintenance. The use of GIS software can effectively solve that
