This project will investigate the extent of HMA pavement damage due to moisture in New England and develop recommendations for test procedures that correlate well with actual field performance.
Tasks could include:
- Identify several pavements or mixes from each state that appear to be prone to moisture damage as well as mixes that perform well.
- Document the moisture testing already being conducted by New England state DOT’s and relevant studies that support this testing.
- Obtain samples and compare the effectiveness of T 283 (the most widely used test) with T 324 (Hamburg) and the method developed using MIST-conditioned specimens in the AMPT. See which method correlates best with observed field performance.
- Recommend best practices for moisture testing of HMA pavements for New England mixes.
- Conduct testing on mixes with lime additive and liquid anti-strip to compare performance.
