Findings: The researcher did establish that spray injection is an effective method for better utilizing personnel to make pothole patches that last considerably longer than those using manual methods. Because of manpower savings and better patching, the method is cost-effective.
Regarding training, the researcher did not recommend a course outline, but discussed how manufacturers and users of spray injection equipment can successfully train operators. Hands-on training is preferable to classroom training.
Overall, the panel felt the research produced an effective report that will be helpful to the Department regarding spray injection applications.
