Accelerated Performance-Related Tests for Asphalt-Aggregate Mixes and Their Usein Mix Design and Analysis Systems

摘要

One of the objectives of the SHRP Project A-003A has been the development of aseries of accelerated performance-related tests to define asphalt-aggregate interactions which affect pavement performance. Tests included those for fatigue, permanent deformation, thermal cracking, aging, and water sensitivity. This report provides a brief summary of the processes which lead to the selection of each of the tests. Inherent in this selection process was the emphasis on the ability of the test to measure fundamental material properties which, when incorporated into prediction models, will depend less on empirical correlations than has been traditionally the case. Also included are the results of validation studies for each of the tests and frameworks for the use of the tests in mix design and analysis. Several levels of design are provided for each distress, some of which incorporate reliability concepts. (Copyright (c) 1994 National Academy of Sciences.)
