DEVELOPMENT OF PAVEMENT MAINTENANCE MANAGEMENT SYSTEM IN KHARTOUM

Abstract

The thesis is concerned with Pavement Maintenance Management System of road for the Khartoum State Paved Network. In this study a street classification system is assessed, comprehensive road inventory, Pavement Visual Condition Survey for the Pavement distresses types’ severity, density and prevent an each road were determined. The study is also includes a complete pavement condition survey and assessment of (30km) from the paved street, the study ranks the project according to its pavement condition index (PCI) to set initial priorities based on “the worst first” concept. It also includes carrying of dynamic cone penetration (DCP) on selected representative sample units from some section of the roads and a correlation between CBR(DCP) and CBR laboratory was found to be 0.62 and also The DCP data were analyzed by the transport road laboratory (TRL) U.K software version 3.1. The Non destructive equipment includes the skid resistance device was carried out. Correlated with PCI and also level of service is carried out for paved road was found that only one street has level of service A, and four of them has level of service B and the rest six street are having level of service C, which will need more access and grade separation for the junctions and to some extent some maintenance is needed for some of them. the study shows that about 17% of the road pavement one in fair condition, 33% of roads are in satisfactory condition,25% are very good, 25% excellent and the average PCI of all the road was found to be 57%.
