ASSESSMENT OF HIGHWAY PAVEMENT DISTRESSES SUBJECTED TO OVERLOADING IN HILLA CITY: A ROAD NO. 80 CASE STUDY

Abstract

Roadway pavements constitute a vital component of transportation infrastructure, and their effective maintenance and rehabilitation are paramount to ensure optimal functionality. Efficient road management systems save time and resources and rely on accurate pavement condition surveys. To ensure optimal functionality, it is crucial to establish a pavement management system (PMS) that involves assessing the current state of the road network and predicting future conditions. In this research, we assessed the effectiveness of asphalt pavements using two well-known approaches: The Present Serviceability Index and The Pavement Condition Index (PCI). The PCI, a numerical index, is a reliable indicator to assess the operational condition and structural reliability of pavements based on visual assessments of distress type, severity, and quantity. We aimed to classify the various types of distress observed on Road No.80 and estimate the pavement condition index. We identified nine out of nineteen distress problems in the pavement section under study through a comprehensive pavement distress condition rating approach. The most prevalent distress types included longitudinal and transverse cracking, rutting, potholes, edge cracking, alligator cracking ,patching and weathering and raveling.
