Asphalt concrete, AC, is a heterogeneous material that is modeled as a homogeneous material. The disparity between material structure and theory presents issue with performance testing with test sample geometries, resulting in variability. The purpose of this research is to develop appropriate sample geometry for AMPT test for accurate characterization of asphalt mix and ease of testing.
Four sample geometries were fabricated for three mix types. All specimens are fabricated at 7%0.5% air voids and tested for AMPT tests. The effect of sample geometry was statistically analyzed using laboratory test results and performance predictions using FlexPAVE. For ranking analysis all …
