APPENDIX H
COST AND BENEFIT SURVEY QUESTIONAIRE

The ASR Lead Team is in the process of assessing costs / benefits of Implementation of SHRP the ASR Technologies and improvements developed in cooperation with the Lead States since conclusion of the SHRP projects. The following survey was designed to provide needed information from AASHTO members in order to make this assessment. Your cooperation in filling out this survey, or asking the appropriate personnel in your department to fill it out, would be greatly appreciated. It is understood that some of the information being requested may not be readily available or easily discernible from existing databases. In these cases your best estimate would be appreciated. Please make sure to mark these areas as "est."

The scope of this project goes beyond, and is planned to be more detailed than, the initial FHWA-sponsored study "Summary of SHRP Research and Economic Benefits of Concrete and Structures" outlined in Research Report Number 96-2 and available through the "RoadSavers" program. The data generated through this survey will be made available to all respondents.

The survey has been subdivided in two sections : 1 ) New Construction, and 2 ) Rehabilitation / Repair / Maintenance of existing ASR affected Pavements and Structures.
