Reliable estimates of the service life and cost of typical maintenance and rehabilitation (M&R) treatments are very important in the implementation of pavement management systems. The primary objective of this project was twofold: (a) to develop and test a survey questionnaire that may be used to obtain reliable estimates of service lives and costs of maintenance and rehabilitation treatments commonly used on local roads in Massachusetts and other parts of New England, and (b) to use the survey questionnaire to estimate the service lives and costs of such treatments in Massachusetts. Sixty-eight cities and towns in Massachusetts were surveyed. The data were analyzed to estimate the service life and cost of thin overlays, chip seals, and sand seals; they were also used as a basis for developing performance curves. (A)
