Tire Rubber Modified Asphalt Emulsion for Effective Pavement Preservation

SPONSOR: MICHIGAN DEPARTMENT OF ENVIRONMENTAL QUALITY

PI:  Zhanping You

This project will evaluate the feasibility of GTR-emulsion and activated rubber for pavement chip seal. The feasibility study includes the emulsification and performance evaluation of GTR-emulsions, and trial field sections of chip seals for GTR-emulsions and/or activated rubber. The project will be considered successful if the following results are obtained:

(1) GTR-emulsion and ARMA is successfully prepared and its performance is evaluated in laboratory. Its properties meet the requirements of each standard. The comparison between regular-emulsion and modified emulsions is made for performance evaluation.
(2) GTR-emulsion and activated rubber chip seals are successfully prepared and the performance is evaluated through the laboratory paving of chip seals. The life cycle cost analysis of chip seals is used to evaluate the ROI and the comparison between GTR-emulsion chip seal and others will be made.
(3) The road trial sections of GTR-emulsion and activated rubber chip seals are successfully implemented.
