Asphalt-Aggregate Mixture Analysis System: AAMAS
The report presents the results of a study to develop an Asphalt-Aggregate Mixture Analysis System (AAMAS) for the evaluation of paving mixtures based on performance-related criteria. Part I of the report presents the guidelines and criteria recommended for selecting the mixture components. It also presents the mixture design procedure, and discusses the test procedures that are required for AAMAS, and discusses the mechanical-empirical procedures used to predict mixture behavior under traffic and environmental loads. Part II discusses development of the different factors that were included in AAMAS. Specific items addressed include compaction of laboratory mixtures to simulate the characteristics of mixtures placed in the field, preparation and mixing of materials in the laboratory to simulate the asphalt concrete plant production process, simulation of the long-term effects of traffic and the environment (this includes accelerated aging and densification of the mixes caused by traffic), and the conditioning of laboratory samples to simulate the effects of moisture induced damage and hardening of the asphalt. The AAMAS methodology as it currently exists is applicable to hot mixed asphaltic concrete, and includes mixture variables such as binders, aggregates and fillers used in the construction of asphalt concrete pavements.
