K - 1 APPENDIX K â Useful Product Life Guidance
2004 AASHTO RAC Meeting Survey Form â The Number of Responses Received for Each Category of Useful Research Product Life Is Indicated Please check the box that in your opinion best represents the useful life of most research products in that category. Useful life is the period of time before the product is either significantly improved by later research or in some way becomes obsolete. There can be considerable variation in useful life between individual products within each category. The purpose of this exercise is to determine the usual or most frequent useful life occurrence for each general category of product. Useful Life Estimate Categories of Research Products â Products may be entirely new approaches or may be an improvement to existing methods or standards < 3 Years 3-6 Years 7-10 Years 11-15 Years 16-20 Years > 20 Years Optional Comment Laboratory Test Methods 1 6 3 3 1 Field Test Methods for Pavements 1 1 7 3 1 1 Pavement Design Methods 1 5 3 3 2 Geometric Roadway Design Standards 3 5 4 1 Structural Bridge Element Design Standards 4 5 2 2 Standard Construction and Maintenance Specifications 6 5 1 2 Quality Control - Quality Assurance Methods 1 6 5 1 1 Equipment Purchase Specifications 7 1 4 1 Inspection Training Videos 1 9 4 On-line or CD-Rom Inspection Training Courses 3 10 1

This National RAC Meeting workshop provides a wonderful opportunity to determine consensus opinions from R&D professionals on this subject. This information will be used in the performance measurement tool box to be developed. This work sheet may be left on the handout table or may be given to the researchers after the workshop.
