The triaxial compression test is one of the most common standard tests for determining the stress-strain behavior and strength parameters of soils under drained and undrained conditions. The use of the test method in asphaltic mixtures is less well known and seldom practiced. This paper describes the use of the triaxial compression test for asphaltic mixtures for determining their engineering properties such as the friction angle ?, the cohesion, c, and the elastic compression modulus, E. Effects of test temperatures, strain rate, and confining pressures on the compressive behavior of asphalt concrete were studied. The results showed that the friction angle is primarily a function of aggregate friction and interlocking, being independent of test temperature and strain rate. The cohesion, on the other hand, is largely dependent on the binder and fines mixture being sensitive to both test temperature and strain rate changes. The confining pressures have no influence on c and ?, but have significant influence on the compression modulus. E. The tests can be conducted at controlled temperatures, constant strain-rate, and confining pressures so as to allow the determination of the basic engineering stress-strain and strength properties of these materials under controlled environmental conditions. Using these properties, a constitutive plasticity model based on the Drucker-Prager yield condition can then be applied in an axisymmetric finite element model to describe the mechanical behavior of the asphaltic material in triaxial compression. Analysis shows that the plasticity model is able to describe the stress-strain behavior of the triaxial specimen to failure, predicting both the failure strain and the failure stress fairly accurately. Comparison of analysis with measured lateral deformation at failure also show good agreement. Thus it seems that a simple idealized elastic-perfectly-plastic constitutive model, whose parameters can be determined from a triaxial compression test at constant strain-rate, is adequate to describe the behavior of asphaltic mixtures, loaded in compression to failure.

The mix design procedure for asphalt mixtures by the Mrshall method does not furnish material property parameters that can be used analytically for structural thickness design and performance analysis of pavements. This research illustrates that this missing link can be bridged by the use of laboratory triaxial test-determined properties to characterize asphalt mixtures. By means of finite element analysis using triaxial test-determined properties as input, it is illustrated that the stress-strain behavior of asphalt specimens up to failure can be simulated for the following three loading conditions: triaxial test, Marshall test, and indirect tension test. Laboratory tests involving four different asphalt mixtures are performed to provide the verification data.

Structural Behavior of Asphalt Pavements provides engineers and researchers with a detailed guide to the structural behavioral dynamics of asphalt pavement including: pavement temperature distribution, mechanistic response of pavement structure under the application of heavy vehicles, distress mechanism of pavement, and pavement deterioration performance and dynamic equations. An authoritative guide for understanding the key mechanisms for creating longer lasting pavements, Structural Behavior of Asphalt Pavements describes the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performances, and demonstrates the process of pavement analyses and designs, approaching science from empirical analyses. Analyzes the external and internal factors influencing pavement temperature field, and provide a review of existing pavement temperature prediction models Introduces a “Bridge Principle through which pavement performance and fatigue properties are consolidated Defines the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performance Summaries the mechanistic response of pavement structure under the application of heavy vehicle, distress mechanism of pavement, pavement deterioration performance and dynamic equations, and life cycle analysis of pavement
