Methodology used for identifying reseal projects in the Western Cape

The Western Cape Provincial Administration, South Africa, uses a pavement management system (PMS) to assist in managing their paved road network. Standardised visual assessments are carried out annually on each surfaced road segment to describe the condition of the road network and to identify the need for remedial action. The need for reseal and priority thereof are based on a calculated reseal condition index (RCI), making use of the degree and extent of observed distress. The RCI and the method for identifying recommended types of seal are given in the paper. This paper provides some background to the Western Cape Road Network, the Administration's Pavement Management System and the annual visual assessment methodology used. Thereafter, the principles and process of calculating the reseal need and the method used for selecting the most appropriate reseal type are discussed. Additional information is provided regarding the expected life of each seal type and the results of an in-depth study of the actual life obtained for seals based on historical data.
