Quality Acceptance Plan for PG Graded Asphalt Binders (With Discussion)
The Superpave Performance-Graded binder specification is based upon material properties that are related to field performance. The test results for these material properties are intended to be used for acceptance and payment purposes. The conformance or non conformance of the material to the specification is decided through the procedure documented in the quality assurance plan that forms a part of the contract agreement for the construction of the pavement. The quality assurance plan is a component of the overall quality management system that needs to be enforced in order to achieve the intended performance of the pavement. This paper presents the essential components of a quality management system for Performance Graded (PG) binders, and a payment protocol developed to a stage that it can be incorporated into the specifications for the PG binders. The overall process of binder acceptance and payment is very complicated due to the potential involvement of a number of different parties including the producer, brokers, terminals and shippers, the supplier (often the HMAC contractor), and the user agency. Acceptance of the asphalt binder is dependent upon the test results from the supplier and user. The potential effects of the variability and bias in these test results must be carefully considered in the acceptance and payment protocol. These considerations led the authors to the development of a statistically based acceptance and payment plan which considers laboratory specific testing variability and bias. This is a different approach than the traditional percent within limit (PWL) method, which requires a large number of samples and testing. The proposed scheme is intended to be reasonable to all the parties by balancing their individual risks. In the future, this payment schedule, contingent upon field verification, can be integrated with performance prediction models as they are developed and verified. In this way, payment for the asphalt binder can be related to the expected performance of the pavement.
