Sensitivity Evaluation of Field Shear Test Using Improved Protocol and Indirect Tension Strength Test

摘要

There were two primary objectives for the research documented in this short report. One objective was to evaluate the sensitivity of complex modulus measurements made using the recently improved field shear test (FST), following a new and potentially more effective testing protocol. The other objective was to evaluate the sensitivity of the indirect tension (IDT) strength test, performed at high temperatures in order to evaluate mixture cohesion and rut resistance. Both of these tests are quick and simple especially the IDT strength test and are thus good candidates for use as field tests for quality control (QC) of asphalt concrete mixtures.
