This paper presents the philosophy of the asphalt-aggregate mixture analysis system (AAMAS) concept and provides a brief discussion on those factors that must be included in the design of optimum paving mixtures based on performance-related criteria. Typically, the structural design of asphalt concrete pavements is based on assumed material Cited by: 3.
asphalt-aggregate mixture analysis system: aamas This manual presents the procedures for an Asphalt-Aggregate Mixture Analysis System (AAMAS) developed under NCHRP Research Project (1).
The procedures included in the manual are intended to be used for the design and evaluation of dense-graded hot-mixed asphalt concrete mixtures, based on Cited by: NCHRP Asphalt-Aggregate Mixture Analysis System HAROLD L.
VON QUINTUS, CHUCK s. HUGHES, AND }AMES A. ScHEROCMAN A summary of the procedures for an asphalt-aggregate mixture analysis system (AAMAS) developed under NCHRP Project (1) is provided. Most of the information is documented and reported in NCHRP Report Specific products resulting from this research effort will include improved specifications for asphalt binders and asphalt aggregate mixtures.
The mixture specifications will be supported by accelerated performance related tests that can be used in an asphalt-aggregate mixture analysis system, an example of Asphalt-Aggregate Mixture Analysis System book is shown in Fig.
A reliability based mix design and analysis system for thermal cracking in asphalt concrete pavements is described and demonstrated in this paper. Asphalt-aggregate mixture performance in terms of low temperature cracking and thermal fatigue is assessed independently for each type of cracking in the specified environment.

The compaction of an asphalt mixture is greatly important for ensuring durable pavement performance.
In the past decades, laboratory compaction methods have been widely used to produce the test specimens, which undergo testing to infer the behaviour of asphalt pavements in the field. 2. Mixture theory formulation for asphalt concrete as a two-constituent mixture. In the mixture theory formulation for asphalt concrete derived in the previous paper by the authors, the mixture of aggregate matrix, asphalt and air voids was considered to be a purely mechanical system in which thermal effects and chemical reactions were ignored.
Therefore, a test method performed directly on the asphalt-aggregate system can effectively evaluate the influence of water in both cohesive and adhesive failure types, leading to a better understanding of the moisture sensitivity of asphalt mixtures (5, 6, 7). / Y.R. Kim, S.L.

This research developed an asphalt-aggregate mixture analysis system (AAMAS) for the design of optimum paving mixtures based on performance-related criteria.
These criteria encompass a wide variety of failure modes, e.g., fatigue cracking, thermal cracking, permanent deformation, moisture damage, age. Asphalt concrete used in flexible highway pavement construction has 5–8 percent air voids immediately after laying of the roadway. Constitutive laws for asphalt concrete developed till now have modelled the mix as a linear elastic or viscoelastic material and have not taken into account the effect of void concentration on the mechanical behaviour of the material.
Superpave represents an improved system for specifying asphalt binders and mineral aggregates, developing asphalt mixture design, and analyzing and establishing pavement performance prediction.
The system includes an asphalt binder specification, a hot-mix asphalt (HMA) design and analysis system, and computer software that integrates the.
Anchor: #i Section 6: Hot-Mix Asphalt Pavement Mixtures Anchor: #i General. Hot-mix asphalt (HMA) is a generic term that includes many different types of mixtures of aggregate and asphalt cement (binder) produced at elevated temperatures (generally between.
The end result of the SHRP work was an overall asphalt/aggregate mixture design and analysis system called Superpave. The Superpave system proposes test procedures and criteria for asphalt binders, aggregates, mixes, designs, and performance prediction methods for HMA materials.

Those activities which do not contribute to the development of these specifications must be curtailed (figure ). Failure mechanism analysis of asphalt–aggregate systems subjected to direct shear loading.
These results show that the mixture manufactured with the aggregate with the highest shape (3) Mixture Evaluation--This group includes papers relating to the need for the design and evaluation of asphalt-aggregate mixtures.
New and improved laboratory and field methods and concepts for evaluation and control of mixtures are described.
