Development of Performance Criteria for Korean Pavement Warranty Specification
Existing road pavement specifications require that contractors meet only certain material and construction conditions regardless of pavement life. However, performance-based warranty specifications guarantee preservation of the product and designate responsibility for repair of defects to contractors. The warranty contracts and specifications for pavements used since the 1960s in Europe have been adopted in several states of the United States based on state-specific needs, and they have also been used in construction projects. In this study, the performance criteria of warranty specifications in Europe and the United States were investigated to develop performance criteria appropriate for Korea. Automated pavement survey equipment was used to inspect and evaluate indicators of pavement performance with regard to certain performance criteria. Each area of pavement was divided into 2-km sections, which were then subdivided into four 500-m segments. Among the numerous possible indicators, cracking, rutting, international roughness index (IRI), and surface defects (e.g., raveling, bleeding, and microcracking) were selected as performance indicators of asphalt pavement, whereas cracking, IRI, spalling, and D-cracking were selected for concrete pavement. Pavement management system (PMS) data from expressways and national highways were collected and analyzed at a 95th percentile confidence level to determine threshold values of the performance indicators. Warranty periods were also determined for newly constructed asphalt and concrete pavements, as well as asphalt overlay pavement. Remedial actions for the performance indicators were also suggested. Performance indicators and threshold values were evaluated by examining the asphalt overlay sections of national highways constructed between 2005 and 2007. As a result, conclusions were drawn about reasonable performance criteria appropriate for Korea.
