The report covers a thermoviscoelastic characterization of two types of asphaltic concrete tested in uniaxial compression and tension at various strain rates and temperatures. The first mixture was preheated, mixed, and compacted at 300 F. The second mixture was preheated, mixed, and compacted at 450 F. The data reduction and results for 55 tests are given in this report. The test conditions were constant strain rate loading over 5 decades of rate and a temperature range of -50 to 150 F. Fundamental material properties (ultimate strain, ultimate stress, ultimate secant modulus, and initial tangent modulus) were obtained in two of the fundamental loading modes, namely, uniaxial tension and uniaxial compression. Ultimate stress does not seem to be a suitable failure criteria for flexible concrete due to the evidence and facts presented. For practical purposes, ultimate strain appears to be a suitable failure criteria for flexible concrete. (Author)
