Using Pavement Condition Index to Evaluate the Condition of Flexible and Rigid Pavements (A Case Study in Sulaimani)

Abstract
Pavement deterioration is a continuous problem that reduces the service life of the roads if they are note treated before they get worsen. Sometimes quality of the materials and construction are not the only reason, if so, still they can be controlled by periodic inspection and maintenance. Pavement condition index is one of the effective parameter which is necessary to be found out for every road and recommended to be updated every year. The objective of this study is to calculate PCI for two roads in Sulaimani city, including both flexible and rigid pavement. The procedure of ASTM D6433 was followed for visual observation of the defects and total station instrument used for locating the real coordinate of the defects on the roads for further actions to be taken. A 720m long Badinan Road surveyed for rigid pavement and it was found that due to lack periodic maintenances, transverse joints spalled and widened with some other defects which resulted an overall PCI of 41.1 (Fair). For flexible pavement a 1620m long HawaryShar road surveyed, although transverse and longitudinal cracking were major defects in the road with some other types of defects, but the road performed with a PCI of 95.5 (Excellent). Some maintenance procedure recommended for both pavement type based on the severity level of the defects.
