In conclusion, thin maintenance surfaces can be cost effective if the following recommendations are followed: 1) Equipment calibration is desired to ensure that the target material quantities are applied during construction, 2) the sampling of the test sections for performance evaluation to ensure that the number of sample units taken is representative of the entire section, 3) the design of the seal coat application rates, and 4) the type of the aggregate and the binder used for the seal coat mix design. However, the short-term data availability from this project prevents a thorough analysis on the impact of the surface treatments to the pavement surface. Therefore, continuous performance assessment is desired to validate and verify the results of this study.
