FRAMEWORK FOR THE DEVELOPMENT OF A SOUTH AFRICAN PRODUCT PERFORMANCE GUARANTEE SYSTEM FOR THE ASPHALT INDUSTRY

The paper deals with the development and implementation of a Product Performance Guarantee System (PPGS) in the South African asphalt industry. The proposed system comprises the formal management of product performance guarantees, in which acceptance criteria are based on the performance of products rather than on their compliance with current prescribed specifications. The system supports aspects such as innovation in materials and design, conditions for acceptance based on performance indicators, as well as formal quality management systems and their development and implementation in the industry. The development and implementation of PPGS are currently proceeding incrementally.
