Improved Conditioning Procedure for Predicting the Moisture Susceptibility of HMA Pavements

The objective of this research is to develop an improved conditioning procedure based on the environmental conditioning system (ECS) for evaluating the moisture susceptibility of compacted HMA in combination with the simpler performance test (SPT) validated in NCHRP Project 9-19. When combined with the SPT for mix design, or with the SPT or other appropriate tests for field quality control and acceptance (QC/QA), the improved conditioning procedure will be sensitive to the effects of normal variability in material and mix properties expected during laboratory mix design and field construction, and will exhibit acceptable levels of repeatability and reproducibility.
