APPENDIX A
Survey Questionnaire and Results
NCHRP Synthesis Topic 41-12
Microsurfacing Best Practices
Questionnaire for Public Agencies and Others
PURPOSE OF THE SYNTHESIS:
The purpose of this synthesis is to capture the various ways federal, state and local transportation agencies are
utilizing microsurfacing as a preventive maintenance and/or pavement preservation treatment. The synthesis
will identify different approaches and effective practices recognizing the differences in each of the climatic
regions. The synthesis will also address how the agencies in the study utilize microsurfacing in high and low
volume traffic conditions. You have been identified as a knowledgeable source for this information and we
would like to synthesize your experience with other pavement maintenance professionals in the US and
overseas to determine those practices that have produced successful microsurfacing projects.
This questionnaire will take approximately 45 minutes to complete. The purpose of this questionnaire
is to collect specific information on microsurfacing practices from sources ranging from the municipal to the
international level. Additionally, those respondents that believe that they have a microsurfacing project that
would make a good case study to illustrate a particularly successful microsurfacing best practice are invited to
indicate their willingness to contribute detailed information about the project, and they will be contacted
individually by the researcher to obtain the case study information.
The results of this synthesis will be shared and distributed through AASHTO, the Federal Highway
Administration, Transportation Research Board, and others, with the goal of assisting in the development and
implementation of microsurfacing as a part of pavement preservation programs. I want to thank you in advance
for your support for this project. This project's results will furnish a means to disseminate the experience of
maintenance engineers from around the world in a very straightforward fashion. Thank you for your time and
information.
