Performance Monitoring of Preservation Treatments in Honolulu

This project will monitor the performance of different preservation treatments in Honolulu, Hawaii. The condition of the treated and control sections will be surveyed prior to the treatment application and then regularly at intervals between 3 and 4 months with the goal of quantifying the benefits of pavement preservation (PP). The treatments considered are fog seal, slurry seal, asphalt seal coat treatments currently available in Honolulu, thin lift overlay, and crack sealing. In addition, pavement temperature with depth will be monitored on one section to validate whether moduli may increase with depth for the Honolulu environment; a situation that is believed to result in high tensile strains near the surface of the pavement and thus affect the performance of pavement preservation treatments. Finally, the materials used for pavement preservation will be tested in the laboratory. Specifically, binders (including emulsion residues) will be tested with a Dynamic Shear Rheometer and a Viscometer, the Wet Track Abrasion will be used for slurry seals, and several performance tests will be carried out for thin lift overlay. The test results will be used to help in writing guidelines and potentially help explaining any unexpected behavior of the treatments.
